Title: Tidal disruption events in active galactic nuclei Abstract: A fraction of tidal disruption events (TDEs) occur in active galactic nuclei (AGNs); distinguishing TDE flares in these hosts from common AGN variability is an unsolved challenge. We took the first step toward characterizing the appearance of TDEs in AGNs with the help of hydrodynamic simulations. … Continue reading "CRA Seminar: Dr. Edwin Chan (CRA)"

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 understood. The variation of the cosmic ray flux with energy is referred to as the "Energy Spectrum.” The measurement of the cosmic ray energy spectrum … 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 evidence for one source, a flaring blazar known as TXS 0506+056. However, the sources responsible for the majority of the astrophysical neutrino flux remain elusive. … 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 of the intergalactic medium (IGM) during the epoch of reionization thanks to the resonant nature of Lyman-alpha scattering with HI. Initial Lyman-alpha studies of multi-object … Continue reading "CRA Seminar: Intae Jung, PhD"
