Title: Formation of Black Hole Binaries in AGN disks through Close Encounters Abstract: The possibility of binary black hole (BH) mergers in active galactic nucleus (AGN) accretion disks has recently received much attention. The community has studied the evolution of pre-existing BH binaries in AGN disks. However, how to form these BH binaries initially remains … Continue reading "CRA Seminar: Jiaru Li (Cornell)"
Title: The role of AGN accretion disks in the formation of characteristic, low-frequency GW sources Accretion disks in active galactic nuclei (AGN) can enhance the formation of gravitational wave (GW) sources via the interaction of embedded stars and BHs with the surrounding gas. This can produce a substantial population of ‘gas-embedded’ GW sources across a range … Continue reading "CRA Seminar: Andrea Derdzinski (U. of Zurich)"
Title: Searches for gravitational-waves beyond compact binary coalescences Abstract: The Advanced LIGO and Virgo detectors have now completed three observing runs, and reported dozens of detections form compact binary mergers. As we observe more of the gravitational-wave universe, we may detect signals from novel sources. For example, core-collapse supernovae or cosmic string cusps may produce … Continue reading "CRA Seminar: Meg Millhouse (GaTech)"
Title: Multiscale Simulations of Star Formation from Molecular Clouds Abstract: Star formation lies at the center of many fundamental topics in astrophysics. No comprehensive, quantitative theory of star formation has been established due to the complex physics involved and the huge dynamic range of the problem. Using a series of MHD simulations of star formation … Continue reading "CRA Seminar: ChongChong He (U. of Maryland)"
