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…
SOFIA/HAWC+ Far-InfraRed Polarimetric Large Area CMZ Exploration (FIREPLACE) Survey I: General Results from the Pilot Program
Natalie O. Butterfield, David T. Chuss, Jordan A. Guerra +9
We present the first data release (DR1) of the Far-Infrared Polarimetric Large Area CMZ Exploration (FIREPLACE) survey. The survey was taken using the 214-micron band of the HAWC+…
A 3D model for the stellar populations in the nuclei of NGC 1433,NGC 1566, and NGC 1808
P. Vermot, J. Palouš, B. Barna +3
Aims. We aim to characterize the properties of the stellar populations in the central few hundred parsecs of nearby galactic nuclei; specifically their age, mass, and 3D geometry.…
Chandra X-ray Measurement of Gas-phase Heavy Element Abundances in the Central Parsec of the Galaxy
Ziqian Hua, Zhiyuan Li, Mengfei Zhang +2
Elemental abundances are key to our understanding of star formation and evolution in the Galactic center. Previous work on this topic has been based on infrared (IR) observations,…
Stellar Populations in the Central 0.5 pc of Our Galaxy III: The Dynamical Sub-structures
Siyao Jia, Ningyuan Xu, Jessica R. Lu +12
We measure the 3D kinematic structures of the young stars within the central 0.5 parsec of our Galactic Center using the 10 m telescopes of the W.~M.~Keck Observatory over a time s…
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…
