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)"

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 mergers detected in gravitational waves (GW) by LIGO-VIRGO-KAGRA. Current observed mergers show distinct properties that may only be explained by this AGN channel, with a … 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"
