StreamGen: Connecting Populations of Streams and Shells to Their Host Galaxies

Kavli Affiliate: Lina Necib | First 5 Authors: Adriana Dropulic, Nora Shipp, Stacy Kim, Zeineb Mezghanni, Lina Necib | Summary: In this work, we study how the abundance and dynamics of populations of disrupting satellite galaxies change systematically as a function of host galaxy properties. We apply a theoretical model of the phase-mixing process to […]

Revealing the state transition of Cen X-3 at high spectral resolution with Chandra

Kavli Affiliate: Norbert Schulz | First 5 Authors: Graciela Sanjurjo-Ferrín, Jose Miguel Torrejón, Lida Oskinova, Konstantin Postnov, Jose Joaquín Rodes-Roca | Summary: Cen X-3 is a compact, high-mass X-ray binary (HMXRB), likely powered by Roche lobe overflow. We present a phase-resolved X-ray spectral and timing analysis of a target of opportunity textit{Chandra} observation made during […]

A search for persistent radio sources toward repeating fast radio bursts discovered by CHIME/FRB

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Adaeze L. Ibik, Maria R. Drout, Bryan M. Gaensler, Paul Scholz, Navin Sridhar | Summary: The identification of persistent radio sources (PRSs) coincident with two repeating fast radio bursts (FRBs) supports FRB theories requiring a compact central engine. However, deep non-detections in other cases highlight the […]

Possible anti-correlations between pulsation amplitudes and the disk growth of Be stars in giant-outbursting Be X-ray binaries

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Masafumi Niwano, Michael M. Fausnaugh, Ryan M. Lau, Kishalay De, Roberto Soria | Summary: The mechanism of X-ray outbursts in Be X-ray binaries remains a mystery, and understanding their circumstellar disks is crucial for a solution of the mass-transfer problem. In particular, it is important to identify […]
