Web:https://phys.washington.edu/people/sanjay-reddy Title: Neutron stars in the multi-messenger era Abstract: About 50 years after their discovery, neutron stars are poised to take center stage in this era of multi-messenger astrophysics.  I will highlight advances in theory and key observations including GW170817 that have provided fundamental new insights about neutron star properties and their central role in … Continue reading "CRA seminar by Dr. Sanjay Reddy (University of Washington)"

Web: https://sites.google.com/view/jcbecker/ Title: Forming hot Jupiters: observational constraints on gas giant formation and migration Abstract: The three commonly considered pathways for hot Jupiter formation are in situ formation, runaway accretion in the outer disk followed by disk migration, and tidal migration (occurring after the disk has dissipated). None of these explains the entire observed sample … Continue reading "CRA Seminar by Dr. Juliette Becker (Caltech)"

Web: https://dark.nbi.ku.dk/people/marianne/ Title: Determining black hole masses of active galactic nuclei across cosmic time Abstract: Observations show that supermassive black holes can affect their environment through outflows and other feedback processes. 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"
