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…
Evidence of a Decreased Binary Fraction for Massive Stars Within 20 Milliparsecs of the Supermassive Black Hole at the Galactic Center
Devin S. Chu, Tuan Do, Andrea Ghez +12
We present the results of the first systematic search for spectroscopic binaries within the central 2 x 3 arcsec around the supermassive black hole at the center of the Milky W…
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…
Rapid Variability of Sgr A* across the Electromagnetic Spectrum
G. Witzel, G. Martinez, S. P. Willner +17
Sagittarius A* (Sgr A*) is the variable radio, near-infrared (NIR), and X-ray source associated with accretion onto the Galactic center black hole. We have analyzed a comprehensive…
Probing Interstellar Grain Growth Through Polarimetry in the Taurus Cloud Complex
John E. Vaillancourt, B-G Andersson, Dan P. Clemens +4
The optical and near-infrared (OIR) polarization of starlight is typically understood to arise from the dichroic extinction of that light by dust grains whose axes are aligned with…
A Survey of 3 to 5.4 Micron Emission From Planetary Nebulae using SOFIA/FLITECAM
Erin C. Smith, Sarah E. Logsdon, Ian S. McLean +7
Here we present the results of an airborne 3-5.4m spectroscopic study of three young, Carbon-rich planetary nebulae IC 5117, PNG 093.9-00.1, and BD 30 3639. These observation…
