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 with no conclusive evidence for their existence. While the classical approach to detect them based on the use of optical and infrared data is limited … 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. … 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 … Continue reading "CRA Seminar: ChongChong He (U. of Maryland)"

Title: Hydrodynamical Evolution of Binary Black Holes Embedded in AGN Disks Abstract: Stellar-mass binary black holes (BBHs) embedded in active galactic nucleus (AGN) disks are promising progenitors of black hole … Continue reading "CRA Seminar: Rixin Li (Cornell)"

Title: Neutrino astronomy with IceCube Connecting Photoelectrons to Supermassive Black Holes Abstract: The IceCube Neutrino Observatory, deployed beneath the South Pole, is the largest optical neutrino telescope in the World. IceCube has been studying a diffuse flux of high-energy (>TeV) astrophysical neutrinos, ever since it reported the first evidence in 2013. However, the sources of … Continue reading "CRA Seminar: Hans Niederhausen"

Title: High accuracy waveform models for high precision gravitational wave astronomy Abstract: Characterization of gravitational wave (GW) signals from the merger of binary black holes (BBHs) heavily rely on accurate … Continue reading "CRA Seminar: Tousif Islam (UMass-Dartmouth)"

Title: Glitches get stitches: The effect non-transient noise in LIGO detectors on astrophysical inference, and what to do about it Abstract: Ground-based gravitational-wave detector networks have detected a deluge of … Continue reading "CRA Seminar: Sophie Hourihane (Caltech)"

Title: Hunting extragalactic tau neutrinos in mountains, canyons, and volcanoes Abstract: The IceCube neutrino observatory discovered a high energy astrophysical neutrino flux extending to ~10PeV in energy. A first generation extragalactic … Continue reading "CRA Seminar: Ibrahim Safa (Columbia)"
