First mid-infrared detection and modeling of a flare from Sgr A*
Sebastiano D. von Fellenberg, Tamojeet Roychowdhury, Joseph M. Michail +24
The time-variable emission from the accretion flow of Sgr A*, the supermassive black hole at the Galactic Center, has long been examined in the radio-to-mm, near-infrared (NIR), an…

New Evidence for a Flux-independent Spectral Index of Sgr A* in the Near-infrared
Hadrien Paugnat, Tuan Do, Abhimat K. Gautam +11
In this work, we measure the spectral index of Sagittarius A* (Sgr A*) between the (1.6 m) and (2.2 m) broadband filters in the near-infrared (NIR), sampling…
