Speaker: Dr. Eric Perlman
Title: Active Galactic Nuclei
Abstract:
About the Speaker:
Dr. Perlman came to Florida Tech in 2007 after postdoctoral fellowships at Goddard Space Flight Center and the Space Telescope Science Institute, as well as research staff and research faculty positions at the Johns Hopkins University and the University of Maryland, Baltimore County.
Dr. Perlman is an observational astrophysicist whose research concentrates on the nuclei of galaxies, their physics and evolution, particularly those in which the central black hole has a large rate of accretion and is abnormally active (the so-called active galactic nuclei). He was a member of the AGN science team for CanariCam, a first-light instrument for the Gran Telescopio Canarias, and is now a science team member for MIRADAS, one of the GTC's third-generation instruments.
Research Interests:
Dr. Perlman specializes in the structure and physics of high-velocity outflows from compact objects and AGN, particularly, jets. He has a strong interest in clusters of galaxies, galactic activity in clusters and observational cosmology. He has taken an active interest in the intersection of quantum gravity and astrophysics. He takes a multiwaveband approach to these subjects, and has worked in virtually every energy range from the radio through gamma-rays. He is interested in the process of accretion, including events that can temporarily make black holes active (tidal disruption events). He pursues interests in astrobiology, particularly the impact of active black holes on habitable planets.
The Far Out Journal Club invites you to join us for an online conversation with Dennis Kois, Executive Director of Yerkes Observatory
From the outer limits of the Milky Way, the Alachua Astronomy Club has started the Far Out Journal Club. Produced by Rich Russin and hosted by past president Terry Smiljanich, the goal is to have a personal, in-depth visit with the authors, artists, musicians, curators, and other cultural icons who bring us the vast world of cultural science and science fiction.
Have you wondered what it would be like to run an observatory? In this episode we welcome Dennis Kois, Executive Director of Yerkes Observatory. Learn about the future of Yerkes Observatory and what is involved in managing it.
Dennis Kois
Executive Director
Yerkes Observatory / Yerkes Future Foundation
Biography:
Dennis Kois is the Executive Director of Wisconsin’s Yerkes Observatory.
When the University of Chicago closed the observatory and transferred ownership to the newly-created Yerkes Future Foundation in 2020, Dennis became the first—and for a year, only—employee.
In the years since Dennis and the non-profit Foundation have raised more than $30 million to begin reimagining and restoring the 1897 observatory and fifty-acre Olmsted-designed landscape. That project is expected to take more than a decade, and some $87 million, to complete.
The observatory, still undergoing restoration, opened to the public in 2022 with a new mission and vision for the institution’s role in the future of astronomy. It has already attracted more than 100,000 visitors for programs, events and tours that bring together science, art and landscape in unexpected and thought-provoking ways.
Also in 2022 the observatory recruited Dr. Amanda Bauer from the Vera Rubin Observatory to become Deputy Director and Head of Science; the first woman to lead astronomy in Yerkes’ 128-year history. Today Yerkes has a full-time staff of 17.

Title: UV Emissions Surrounding Galaxies
The circumgalactic medium (CGM) and intergalactic medium (IGM), the tenuous gas surrounding galaxies represent a significant portion of matter in the universe as indicated by both theoretical and observational studies. This faint and diffuse gas is not well studied since it is very challenging to observe. Studying the CGM is essential for understanding astrophysical principles that govern the formation and evolution of stars and galaxies throughout the universe. It is believed to be the reservoir of gas and material that is both the source and regulator of star-forming fuel, controlling the exchange between the intergalactic medium (IGM) between galaxies and interstellar medium (ISM) within galaxies. We advance our understanding of these processes through ultraviolet (UV) spectroscopic CGM emission line observations in high redshift galaxies in addition to instrumentation work for balloon-borne and space telescopes that target low redshift galaxies. I present four distinct but interrelated projects that combine observational astronomy, instrument building, and technology development. This includes quasar observations from the Palomar Cosmic Web Imager (PCWI), instrument work on FIREBall-2 (Faint Intergalactic-medium Redshifted Balloon) telescope and Aspera SmallSat mission, and technology development of UV reflective gratings.

The Far Out Journal Club invites you to join us for an online conversation with esteemed author Dava Sobel
Get ready for a special evening as we host Dava Sobel for an online conversation about her career and the critically acclaimed books she has written. Her stories take readers on a trip back in time, placing you squarely in the center of major discoveries as they unfold. Backed by masterful research, she brings you the story behind the story.
Dava Sobel
Author | Historian | Biographer
Self Portrait:
"I have spent my entire professional life writing, including two years as a staff reporter in the Science News department of The New York Times.
New York City born and raised, I grew up within walking distance of the Bronx Zoo and the Botanical Gardens, and attended the Bronx High School of Science (class of 1964). I was a lost soul in college (several changes of majors at three different schools). Fortunately for me, no one around me thought it odd or ill-fated for a girl to be interested in science.
Working freelance for a variety of magazines kept me busily employed until the publication of Longitude in 1995—and its unexpected success—allowed me to write books that require years of research. (I should add that I enjoy that part.)"
Dava Sobel is the author of Longitude (Walker 1995, Bloomsbury 2005), Galileo's Daughter (Walker 1999 and 2011), The Planets (Viking 2005, Penguin 2006), A More Perfect Heaven (Walker/Bloomsbury 2011 and 2012), And the Sun Stood Still (Bloomsbury 2016), The Glass Universe (Viking 2016, Penguin 2017) and The elements of Marie Curie (Grove/Atlantic 2024). She has also co-authored six books, including Is Anyone Out There? with astronomer Frank Drake, and currently edits the “Meter” poetry column in Scientific American.
Awards:
2001 Individual Public Service Award from the National Science Board “for fostering awareness of science and technology among broad segments of the general public.”
2001 Bradford Washburn Award from the Boston Museum of Science for her “outstanding contribution toward public understanding of science, appreciation of its fascination, and the vital roles it plays in all our lives.”
2004 Harrison Medal from the Worshipful Company of Clockmakers, London, in recognition of her contribution to increasing awareness of the science of horology by the general public.
2008 Klumpke-Roberts Award from the Astronomical Society of the Pacific for “increasing the public understanding and appreciation of astronomy.”
2014 Cultural Award from the Eduard Rhein Foundation of Germany “for using her profound scientific knowledge and literary talent to combine facts with fiction by merging scientific adventures and human stories in order to give the history of science a human face.”
Books:
The Far Out Journal Club highly recommends you check out one of her excellent books to further enhance your enjoyment of the episode.

“There is a very short list of biographers whose books you’ll read regardless of who the subject happens to be. And there is, perhaps, an even shorter list of brilliant science communicators who can make complex subjects both accessible and fascinating. At the center of that Venn diagram is Dava Sobel. The Elements of Marie Curie may be her best book yet. I am absolutely scandalized by how little I actually knew about this extraordinary, accomplished, and inspiring woman. What a deeply satisfying read!”

Title: Dark Energy
Originally from Fairfield, Connecticut, an early interest in philosophy led to his current interest in cosmology. He attended public high school, received a BA summa cum laude from Princeton (2011), working with J. Richard Gott, III on his senior thesis, an MSt in philosophy of physics at Oxford (2012), and a PhD in Astrophysics (2016) from Harvard, advised by Daniel J. Eisenstein. During his PhD, he focused on Baryon Acoustic Oscillations (BAO) in the 2-point and 3-point correlation function (3PCF) of galaxies, constraining a possible systematic sourced by high-redshift baryon-dark matter relative velocities using the 3PCF. This entailed developing a transformatively fast 3PCF algorithm, enabling the first high-significance detection of BAO in the 3PCF and a measurement of the cosmic distance scale six billion years ago to percent precision. Post-PhD, he spent one year as a Chamberlain Fellow and one year as an Einstein Fellow at Lawrence Berkeley National Laboratory, where highlights included an implementation of the 3PCF algorithm capable of computing the 3PCF for the entire observable Universe in 20-hours on NERSC’s Cori supercomputer, application of the 3PCF to MHD turbulence, and novel analytic solutions for the Friedmann equation in the presence of neutrinos or warm dark matter.
Dark energy, dark matter, structure formation, large surveys, analytic methods, star formation. His current research follows three broad paths: creating theoretical models for large-scale structure, designing fast algorithms to measure it, and applying them to datasets such as BOSS, eBOSS, and DESI. Cutting across these areas are a strong attraction to analytic methods and excitement about effective use of high-performance computing.
