Near-Infrared Flux Distribution of Sgr A* from 2005-2022: Evidence for an Enhanced Accretion Episode in 2019
Grant C. Weldon, Tuan Do, Gunther Witzel +10
Sgr A* is the variable electromagnetic source associated with accretion onto the Galactic center supermassive black hole. While the near-infrared (NIR) variability of Sgr A* was sh…
The Swansong of the Galactic Center Source X7: An Extreme Example of Tidal Evolution near the Supermassive Black Hole
Anna Ciurlo, Randall D. Campbell, Mark R. Morris +14
We present two decades of new high-angular-resolution near-infrared data from the W. M. Keck Observatory that reveal extreme evolution in X7, an elongated dust and gas feature, pre…
Measuring the Orbits of the Arches and Quintuplet Clusters using HST and Gaia: Exploring Scenarios for Star Formation Near the Galactic Center
Matthew W. Hosek, Tuan Do, Jessica R. Lu +4
We present new absolute proper motion measurements for the Arches and Quintuplet clusters, two young massive star clusters near the Galactic center. Using multi-epoch HST observati…
Kinematics and Feedback in H II regions in the Dwarf Starburst Galaxy IC 10
Maren Cosens, Shelley A. Wright, Norman Murray +8
We present a survey of the central region of the nearest starburst galaxy, IC 10, using the W. M. Keck Observatory Keck Cosmic Web Imager (KCWI) at high spectral and spatial resolu…
Revealing the Formation of the Milky Way Nuclear Star Cluster via Chemo-Dynamical Modeling
Tuan Do, Gregory David Martinez, Wolfgang Kerzendorf +4
The Milky Way nuclear star cluster (MW NSC) has been used as a template to understand the origin and evolution of galactic nuclei and the interaction of nuclear star clusters with…
A population of dust-enshrouded objects orbiting the Galactic black hole
Anna Ciurlo, Randall D. Campbell, Mark R. Morris +9
The central 0.1 parsecs of the Milky Way host a supermassive black hole identified with the position of the radio and infrared source Sagittarius A*, a cluster of young, massive st…
