Title: Intermediate-mass black holes: past, present, future Abstract: Despite their key importance from stellar to cosmological scales, intermediate-mass black holes (IMBHs) are one of the unsolved puzzles of modern astronomy … Continue reading "CRA Seminar: Giacomo Fragione (Northwestern)"

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 … 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) … 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)"
