Astrophysical Sciences and Technology Colloquium
Binary Massive Black Holes, Active Galactic Nuclei, and Gravitational Waves
Dr. Luke Kelley

Assistant Adjunct Professor at UC Berkeley

We are viewing in person in 1125 Carlson Hall, but there is a Zoom Link for those unable to attend in person.

Massive black holes (MBHs) are the brightest, most massive, and most energetic sources in the Universe. How they form and grow in the early Universe, and how they can transform their host galaxies, remains a mystery. Following galaxy mergers, pairs of MBHs can form binaries which produce low-frequency gravitational waves (GWs) that will soon be detectable by pulsar timing arrays, like NANOGrav. In this talk, Dr. Kelley will describe his efforts to develop the most advanced and comprehensive simulations available for studying MBH binaries. He will share predictions for both GW and electromagnetic signatures and highlight the unique discovery space opened upby low-frequency multimessengerastrophysics. In addition to constraining the co-evolution of MBHs and galaxies over cosmic time, NANOGravwill also serve as a crucial test-bed for the future space-based LISA mission.

Speaker Bio:
Luke Kelley is an assistant adjunct professor at UC Berkeley, where he started just this year after being a CIERA, Lindheimerand Cottrell postdoctoral fellow at Northwestern University. He is a broad astrophysical theorist working at the interface of high-energy transients, gravitational waves, and galaxy evolution. Luke completed his PhD in Astronomy & Astrophysics at Harvard University in 2018 working with Lars Hernquist, after completing undergraduate degrees in Physics and Biology at the University of California at Santa Cruz.

Intended Audience:
