In order to establish the exact role that supermassive black holes play for galaxy evolution, we need to determine accurately the mass of the … Continue reading "CRA Seminar by Prof. Marianne Vestergaard (Niels Bohr Institute, Univ. of Copenhagen)"

Abstract: With energies greater than a PeV, cosmic rays from galactic (and extra-galactic) sources are too rare to detect directly.  Instead, large ground-based detector arrays catch the secondary particles from the extensive air showers that cosmic rays produce in the atmosphere, and attempt to determine … Continue reading "CRA Seminar by Prof. Katherine Rawlins (U. Alaska)"

Title: Gravitational Wave Sources at the Hearts of Galaxies Abstract: The recent gravitational-wave detections by LIGO/Virgo revolutionized the way we sense our Universe. However, it remains challenging to explain the formation channels of these sources. Motivated by these challenges, recent studies have emphasized the significant contribution of dynamical formation channels in dense stellar environments to … Continue reading "CRA Seminar: Prof. Smadar Naoz"

Title: Halo-Bar Coupling: How Dark Matter Defines Galaxies Abstract: The coupling of a host dark matter halo to a stellar bar can have huge effects on galaxy dynamics and evolution. … Continue reading "CRA Seminar: Angela Collier"

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 … 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 … Continue reading "CRA Seminar: Mathew Potts (University of Utah)"
