As a successful astronomer, I have had the good fortune to observe at some of the world’s largest telescopes -- the Magellan Telescopes in Chile, the Canada-France-Hawaii Telescope and the Keck Observatory atop Mauna Kea, Hawaii. I have also travelled around the world to present my research at conferences. Inevitably, on every plane trip, the person sitting next to me would ask where I am going and what I do. I have noticed that if I say I am an “astronomer”, their eyes get wide and I am peppered with question after question regarding science discoveries that they have read about, heard about, or seen on TV. I have always found these conversations heartening because it demonstrates that the public at-large is really interested in science, our perspective of the Universe, and wants to learn more about it. However, if I mention to my neighbor that I am an “astro-physicist”, I get “Physics? You must be so smart to spend your life studying that subject. I hated that subject in school.” While this may be a momentary ego boost, I have come to realize that what these intelligent, educated, articulate people are really telling me is that they all have had a frustrating, intimidating experience with a subject that I love. Must physics teaching be like this? My goal as a science educator is to not only share my knowledge and passion for science, but to also convey to my students the dynamic nature and excitement of science and why it should also matter to them.
Physics is not simply a collection of facts and formulas although our students want to see it that way. Science is a mode of thought that allows us to critically engage our world and attempt to understand why things work the way they do. I want my students, motivated by curiosity and creativity, to see science at work in their everyday lives, to have the ability and confidence to know that they, too, can understand how the Universe works.
I am an experienced instructor who has taught a wide diversity of classes; from Astronomy and Physics, to Mathematics and Science Education. I have created, organized, prepared, and led courses from 10--100 participants. I have taught students, from pre-K to college seniors, with a broad range of backgrounds, preparation, and learning abilities. I take considerable pride in that I have consistently earned excellent teaching evaluations from my students.
Starry Nights is a week-long series of events designed to raise awareness about light pollution and the steps we can take to end it in our community. Light pollution — the overuse and misuse of artificial light at night — wastes money, wastes energy, endangers our physical, mental, and spiritual health, takes a tremendous environmental toll, and erases the stars from our skies. Worst of all, we have bought into the idea that more light makes us safe. Smarter use of light makes us safe, saves cities/universities/homeowners money, is better for our health and our environment. We can have responsible lighting that ensures our safety and security without polluting our nights. Please join us in celebrating the night and learning how we can implement solutions right here, right now!
Starry Nights, launched in 2014, was created by Dr. Paul Bogard, acclaimed author of The End of Night: Searching for Natural Darkness in an Age of Artificial Light, and Shanil Virani.
Shanil Virani's research has primarily focussed on three distinct areas: science education & communication, fundamental research related to astrophysical phenomena, and spacecraft science operations. An extensive and detailed bibliography can be found by clicking on the Publications tab.
Science Education & Communication
Science may be "under attack" by some politicians in the United States but the problem is really much deeper. Nearly 1 in 2 Americans think there is no evidence for climate change or think it is due to natural causes. Approximately 1 in 4 Americans (and 1 out of 3 Europeans) think the Sun revolves around the Earth. Nine out of 10 Americans can't explain basic phenomena like the cause of the seasons nor the phases of the Moon (yes, even at Harvard). ~5 decades ago we sent 12 men to the Moon. Then we stopped going. Many Americans now think that the Moon landings are a Hollywood hoax. July 20, 2019 will be the 50th Anniversary of Neil Armstrong and Buzz Aldrin walking on the Moon. There is more technology and computational power in our smartphones than was in the computers used to put those 2 men on the Moon. It is a terrible irony that at a time of great scientific and technological advancements, that scientific illiteracy is at an all time high.
We teach science poorly, our kids are not learning science, and therefore, we produce fewer and fewer scientists and engineers. At 5 years of age, every kid is a scientist! They are asking questions about the world around them and why things work the way they do. Then something happens. We spend the next ~20 years beating their innate curiosity and inquisitiveness about their world out of them. In fact, almost twice as many bachelor’s degrees were awarded in physics the year before Sputnik, deemed a time of dangerous educational neglect, than in 2007! The launch of Sputnik was a galvanizing moment in the history of our country and you can trace the start of the “Space Race” to that singular event. It started an enormous investment in science, in engineering, and in education by our government. Yet today we are doing worse than the year before Sputnik was launched.
What does it mean to our country if our society is scientifically illiterate? Does it matter? What does it mean for our country's future prosperity and economic growth? Will American leadership in science and engineering be maintained in the coming years? What about our future capacity for innovation and entrepreneurship? And what does attacks on science mean for the future of our planet? Americans two generations ago walked on the Moon. What is our legacy? These are some the questions I’ve thought about and spoken about within my community. I think we are at an important crossroads in the United States. We need to engage and have deep, meaningful conversations with the American public about the nature and role of science in our country, how we teach it, and why it is critically important that we encourage many more young Americans to consider careers in science and engineering.
I host a weekly, 90-second series on my local NPR station entitled Our Island Universe. This weekly series is a look at all things space — how what goes on “up there” affects us “down here”. While topics generally cover how our ancestors viewed the night sky, to new discoveries in astrophysics, it really is an opportunity for me to share my passion for science and why science matters. It is also an opportunity to talk about how science is done and how we know what we know. Astronomy is a shared cultural connection and by telling stories of our past and present, I hope to inspire the future.
Science is constantly changing, constantly uncovering new clues about our place within the Cosmos. Even more incredible, there are actually people who get paid to figure out why the Universe is the way it is and not some other way! I think it is important for the public to see science "in action", to see people engaged in the discipline, advancing our understanding of our address in the cosmos, and just as importantly, sharing their passion and their enthusiasm for their research. Beginning in Fall 2012, I created and have curated a series of special Planetarium Public Science Talks that is intended for a general audience to see the scientist at play in their sandbox -- the Universe. These are speakers I have intentionally sought and invited because I think the science they are doing is really cool AND also because I think they will give a dynamic public presentation. Billed as "intellectual nourishment" for the mind, these presentations now routinely draw upwards of 300 people to a large auditorium to hear "cutting edge" science. Every presentation is presented on Facebook live but is also recorded and available via the Planetarium's YouTube channel. Past speakers include Dr. Scott Ransom (Pulsars, Magnetars, Black Holes, Oh My! The Wickedly Cool Stellar Undead), Dr. Heidi Hammel (Pluto: Planet or Pretender?), Dr. Jason Kalirai (Telescopes as Time Machines: The Hubble Space Telescope's Outrageous Legacy & the Future to Come with the James Webb Space Telescope), and former Chief Engineer and now Manager of the NESC Integration Office at NASA/Langley, Ms. Jill Prince (Journey to Mars: NASA's Path to the Red Planet)! My personal highlight was hearing JMU colleague and Professor of Mathematics & Statistics, Dr. Caroline Lubert, discuss her acoustic research at NASA's Wallops Island Flight Facility (When I Grow Up, I Want to be a Rocket Scientist)!
In order to reach impressionable young Americans at a time when they are thinking of what they want to pursue when they grow up, I created three, week-long Space Explorers summer camps that take place at the John C. Wells Planetarium. Each camp is broken by grade level. I created and lead a half-day camp for rising 2nd to 4th grade students, a full-day camp for rising 5th to 8th grade students, and a residential camp at JMU for rising 8th to 10th graders! Via these camps housed at a state-of-the-art planetarium, I seek to inspire and excite the next generation of scientists and engineers. These engaging, hands-on, inquiry-based camps demonstrate to students that science is constantly changing, constantly uncovering new clues about why our universe is the way it is and not some other way. We ask basic questions about the natural world and then use the scientific method to try to answer them. For example, we investigate the size and scale of our solar system, learn about the robotic exploration of it, and learn about our own planet Earth and our fragile environment. Each summer I try to arrange special Space Explorers camp visitors that may include JMU science professors, engineers working at NASA on new missions, and perhaps even a NASA astronaut!
How do you become something you don't see? We've long known that the lack of diversity in STEM (science, technology, engineering, and mathematics) fields has been a persistent problem for decades. When we asked our Space Explorers to describe what they think a scientist looks like, we see traditional stereotypes of "white", "male", and "old" year after year in their illustrations. Are scientists really different from everyone else? Are they "six sigma deviants" on some Bell curve?! We say science is for everyone but our caricatures of scientists, our words, and our actions say something else. We cannot continue to exclude from our classrooms and labs roughly half of our population. By doing so, we are not only limiting the conversation but we are also excluding bright minds that can bring their talent to bear on some really tough problems.
A recent NSF study shows that white men currently make up 51 percent of all STEM jobs despite making up only 31 percent of the population — which means women and most minority groups are underrepresented and underserved. Not only does this contribute to race and gender wage gaps — STEM workers typically have higher salaries and currently enjoy a lower rate of unemployment than the general working population — but it also critically shortchanges the STEM community, since it means there are talented minds that haven’t been reached and important perspectives that are missing. Science Sunday for Girls is my small contribution in encouraging young American girls in the Valley to consider careers in science & engineering. Science is for everyone and its important that young girls know that and see that in action!
We have submitted several papers now on what we have learned first-hand about the kinds of hands-on, engaging, inquiry-based activities that lead to the largest gains in deep student learning. In addition to reaching young Americans, our summer Space Explorers camps and Science Sunday for Girls events provide JMU pre-service students and physics majors interested in teaching with real, hands-on teaching experience, learning how to differentiate their instruction for the various students that attend our camps and events, as well as how to teach science that naturally stokes a student's own curiosity about the natural world.
It is now recognized that every galaxy likely hosts a supermassive black hole that lurks at its center. Supermassive black holes that show signs of devouring material in its immediate vicinity are called "Active Galactic Nuclei" (AGN). Much of my astrophysical research has involved carrying out surveys and studies to better understand the AGN phenomenon and to understand the relationship between the supermassive black hole at the center and its host galaxy. In order to understand the nature of activity in galactic nuclei, in particular how it is initiated and maintained, it is reasonable to begin with the question, how do active galaxies compare with non-active galaxies? But any such statistical comparison is fraught with difficulty since this, at least ideally, requires an understanding of the biases in the samples selected. Moreover, it is not clear just which parameter(s) should be compared. Could an active nucleus, especially in the more luminous members of the active galactic nuclei (AGN) family, have a significant effect on "macroscopic" scales; that is, not only on the immediate circum-nuclear environment, but even on the structural parameters of the host galaxy? For these reasons, a comparison of the environments of AGN has been of particular interest in the past three decades, motivated largely by the widely held hypothesis that interactions and mergers play a significant role in initiating activity of the supermassive black hole.
My specific research goals have been to probe hidden populations of supermassive black holes heretofore missed in previous surveys of active galactic nuclei in both the nearby and distance Universe. Using the Chandra X-ray Observatory, a space-based, NASA "Great Observatory", we stared at what we thought was a blank region of the sky at least as it appears to be as seen by the eye. This "blank" area on the sky has now been imaged by the Hubble Space Telescope, the Spitzer Space Telescope, the Chandra X-ray Observatory, and virtually every major telescope on the ground. Using 250,000 second exposures of 4 flanking fields -- called the Extended Chandra Deep Field-South -- this is one of the largest and deepest surveys ever performed with this Observatory. As the Chandra X-ray image embedded in the text shows, this area is anything but blank! In fact, MOST of the sources you see in this image are active supermassive black holes in the centers of galaxies betrayed by the gas swirling around it! These sources have been extensively followed up from the ground using some of the largest ground-based telescopes located in Hawaii and Chile.
In addition to my research related to the Extended Chandra Deep Field-South, I was also responsible for carrying out one of the deepest surveys of the hard X-ray sky ever done. We obtained 3 million seconds of time with the space-based International Gamma-Ray Astrophysical Laboratory (INTEGRAL) to find so heavily obscured AGNs in the nearby universe that they don't appear in traditional AGN surveys. I was also awarded time for follow-up observations with the Chandra X-ray Observatory and with Japan's Suzaku space observatory. One of my more exciting results was finding a "precocious" supermassive black hole in the early Universe. Using the Chandra X-ray Observatory, we imaged and characterized the X-ray spectrum of an AGN found at a redshift of 6, i.e., at a time when the Universe was only ~800 million years old. Our results for the energy index and α_ox are consistent with no strong evolution in the active galactic nucleus emission mechanism with redshift out to z~6 and therefore with the picture that massive black holes have already formed less than 1 Gyr after the Big Bang. The background image to this page shows an artistic creation of what the central engine of an AGN may look like. This research result was the subject of a NASA/Chandra press release and was also highlighted as a "High Energy Astrophysics Picture of the Week" entitled "Black Hole Too Young?". To understand how AGN activity may have impact on their host galaxies on "macroscopic" scales, I developed a technique that permitted the robust decomposition of the bulge and disk components of a local sample of Seyfert galaxies (i.e., in the nearby Universe), as well as a (control) sample of nonactive galaxies matched to the Seyferts in the distributions of redshift, luminosity, and morphological classification. The structural parameters of the host galaxies in both samples were measured. No statistically significant differences at greater than the 95% level are found in these parameters according to a Kolmogorov-Smirnov test. Similarly, I found no statistically significant differences between the control and active sample host galaxies in terms of light asymmetries-bars, rings, isophotal twisting, etc. Since AGN were first discovered some 50 years ago, much work still remains in attempting to resolve these enigmatic objects and the role they play in the formation and evolution of galaxies.
Spacecraft Science Operations
The Chandra X-ray Observatory is a space-based, "Great Observatory" that has revolutionized our view of the X-ray universe. It is NASA's flagship X-ray observatory, just like the Hubble Space Telescope is NASA's flagship optical observatory. Launched in 1999 onboard the space shuttle Columbia, the Chandra X-ray Observatory's unprecedented resolution allows high energy astrophysicists like me to find extreme objects in the Universe. In order to image the high energy universe at a sharp focus, the mirrors on the Chandra X-ray Observatory are exquisitely polished. If the state of Colorado was as smooth as Chandra's mirrors, Pikes Peak would be less than one inch tall! We new immediately what an incredible research facility this observatory was to become. The image below shows "Leon X-1", named after the Chandra Telescope scientist Dr. Leon VanSpeybroeck who designed the mirrors. It was detected in the very first image that was taken right after the Observatory opened its sunshade door to the X-ray universe. This new X-ray source was found to be an unobscured active galactic nucleus at redshift z=0.3207 and had not been detected before. I will never forget that day when we commanded the Observatory door to open and the very first X-ray photons from the Universe began collecting on our instrument. It is a highlight of my life. Designed for a mission lifetime of 5 years, in 2001 NASA extended Chandra's lifetime to 10 years "based on the observatory's outstanding results." In 2014, NASA's Senior Review committee reviewed the Chandra X-ray Observatory, the Hubble Space Telescope, and all other NASA missions. In reviewing the scientific productivity of the Observatory, the committee once again endorsed an extension of the mission stating "Chandra is the most powerful facility for X-ray astrophysics, and its unique capabilities have no likely successor in the foreseeable future."
The Smithsonian Astrophysical Observatory, half of the Harvard-Smithsonian Center for Astrophysics located in Cambridge, MA, is charged with operating and carrying out its mission on behalf of NASA. For 5+ years, I was part of the Science Operations Team responsible for monitoring the health and safety of the Observatory and its instruments, as well as scheduling the Observatory to maximize its science return. The primary instrument onboard the Chandra X-ray Observatory, responsible for carrying out more than two-thirds of all observations is the Advanced CCD Imaging Spectrometer (ACIS). I was part of the ACIS Operations team at the Harvard-Smithsonian Center for Astrophysics and worked closely with the instrument teams at MIT and PSU. Specifically, since the Observatory only makes contact with the ground once every ~8 hours via NASA's Deep Space Network, I wrote several software programs that monitored the health and safety of the ACIS during every real-time contact with the Observatory. I also wrote software that automated the review and checks of the mission command schedule that would be uploaded every week to be executed by the Observatory autonomously to carry out its science observation schedule. One of the key contributions I made to operating and maintaining the Observatory happened very early after launch. One month into the mission, we noticed that the instrument was suffering radiation damage. We quickly figured out that during perigee passage through the Earth's Van Allen belts, the mirrors on the Chandra X-ray Observatory were not only incredible at focussing X-ray photons from the Universe, they were also very good at focussing low energy protons from the Van Allen belts onto the instrument, causing "charge transfer inefficiency" (or CTI), which meant our spectral resolution was rapidly disappearing. Working with scientists at NASA's Marshall Space Flight Center, we quickly developed a brand new radiation model suitable for Chandra's elongated, elliptical orbit and used it to schedule science observations as well as when to shutdown for perigee passage through the Van Allen Belts. Not only did this new radiation model limit further degradation to the instrument, we also realized that we can more efficiently schedule the observatory such that we could regain up to 250,000 seconds of additional science time per year!
Working for a world-class research facility like the Chandra X-ray Observatory, I quickly learned that the images one typically sees in the press is literally the tip of the iceberg of what has to happen to make that observation possible. I also learned first-hand how incredibly smart, approachable, and dedicated the team of scientists and analysts responsible for the Observatory are in carrying out its mission. I was truly fortunate to have spent 5 years with such an outstanding team and my time at the CfA is definitely a highlight of my life!

Our Island Universe
Shanil created and hosts a series called Our Island Universe produced in partnership between WMRA, the Shenandoah Valley's NPR station, and the John C. Wells Planetarium. All episodes are written and presented by Planetarium Director Shanil Virani, and produced by Matt Bingay. Shanil Virani is the Director of the John C. Wells Planetarium and an instructor in the Department of Physics & Astronomy at James Madison University. Matt Bingay is the Assistant General Manager and Program Director for WMRA.
Our Island Universe is a weekly, 90-second look at all things space -- how what goes on ``up there'' affects our life ``down here''. The central themes are to promote the public understanding of science, our exploration of the natural world, and how modern science is really a continuation of our species natural desire to understand the cosmos and our perspective within it. Topics cover how our Ancestors viewed the night sky to new discoveries in astrophysics. Astronomy is a shared cultural connection and by telling stories of our past and present, we hope to inspire the future.
