Learn more about Dr. Intae Jung Title: Probing the Era of Reionization with Lyman-alpha Observations Abstract: Lyman-alpha emission has played a pivotal role in constraining the neutral hydrogen (HI) fraction … Continue reading "CRA Seminar: Intae Jung, PhD"
There will be an in-person viewing of the online seminar held in the CRA Visualization Lab (Boggs 1-44). Title: Astrometric Methods for Star-Based Navigation Abstract: Humans have used stars for navigation since antiquity. It should come as no surprise, therefore, that star sightings were amongst the first observables used to navigate exploration spacecraft (both crewed … Continue reading "CRA Seminar: Dr. John Christian"
Title: Tilted Planets: Exciting Exoplanetary Obliquities via Spin-Orbit Resonances Abstract: The obliquity of a planet, the tilt between its spin and orbital axes, reflects the evolutionary history of the planet. … Continue reading "CRA Seminar: Yubo Su (Princeton University)"
Title: Black hole mergers in AGN disks and Few-body code SpaceHub Abstract: Active galactic nucleus (AGN) disks may be important sites for stellar mass binary black hole (BBH) mergers, but … Continue reading "CRA Seminar: Yihan Wang (Nevada Center for Astrophysics)"
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)"
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)"
