Watch a Bulletin virtual program featuring members of the LIGO/Virgo collaboration, Daniel Holz and Vicky Kalogera, as they discuss how their work will change the way scientists think about astrophysics and the Universe.

In this conversation moderated by Bulletin governing board member Cyndi Conn, you’ll learn how LIGO and Virgo detectors are able to “hear” in gravitational-waves the collisions of neutron stars and black holes – confirming Einstein’s predictions from a century ago. As noted in a New York Times article published earlier this month, the ability to listen to gravitational waves opens up an entirely new and exciting window and “rewrites what we know about our universe.”

Daniel Holz is a professor at the University of Chicago in the Departments of Physics, Astronomy & Astrophysics, the Enrico Fermi Institute, and the Kavli Institute for Cosmological Physics and is a member of the Bulletin of the Atomic Scientists’ Science and Security Board. His research focuses on general relativity in the context of astrophysics and cosmology. He is a member of the Laser Interferometer Gravitational-Wave Observatory (LIGO) collaboration, and was part of the team that announced the first detection of gravitational waves in early 2016 and the first multi-messenger detection of a binary neutron star in 2017. He received a 2012 National Science Foundation CAREER Award, the 2015 Quantrell Award for Excellence in Undergraduate Teaching, and the Breakthrough Prize in Fundamental Physics in 2016. Holz was selected as a Kavli Fellow of the National Academy of Sciences and is a Fellow of the American Physical Society. He received his PhD in physics from the University of Chicago and his AB in physics from Princeton University.

Vicky Kalogera is the co-founder and the current director of the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) and the Daniel I. Linzer Distinguished University Professor in the Department of Physics and Astronomy in the Weinberg College of Arts and Sciences at Northwestern. Kalogera is a leading astrophysicist in the LIGO Scientific Collaboration (LSC), LIGO being the telescopes that first detected gravitational waves in 2015. An expert in the astrophysics of black holes and neutron stars and in LIGO data analysis, Kalogera has been a member of the LSC for more than 15 years, and was elected a member of the US National Academy of Sciences in 2018. Kalogera’s astrophysics research involves methods from applied mathematics, statistics and computer science, with extensive use of high-performance computing. In parallel to her gravitational-wave source studies, Kalogera also studies the formation and evolution of stars and their remnants detectable as gamma-ray, X-ray, and radio pulsar sources in the electromagneticspectrum in a wide range of stellar environments. For her research she has been recognized by numerous awards; most recently she was awarded the 2018 Heineman Prize for Astrophysics by the American Institute for Physics and the American Astronomical Society.
