Title: Ultra-High Energy Cosmic Ray Energy Spectrum using Hybrid Analysis with TAx4 Abstract: Cosmic rays are subatomic particles of extraterrestrial origin and at the highest energies, they are not well … Continue reading "CRA Seminar: Mathew Potts (University of Utah)"
Title: Search for Southern Sky Neutrino Sources with IceCube Abstract: The IceCube Neutrino Observatory has measured a flux of astrophysical neutrinos. More recently, it has used muon-neutrino datasets to present … Continue reading "CRA Seminar: Steve Sclafani"
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 … 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) 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)"
