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 o…
Simultaneous multicolour optical and near-IR transit photometry of GJ 1214b with SOFIA
D. Angerhausen, C. Dreyer, B. Placek +24
The benchmark exoplanet GJ 1214b is one of the best studied transiting planets in the transition zone between rocky Earth-sized planets and gas or ice giants. This class of super-E…
Observations of Type Ia Supernova 2014J with FLITECAM/SOFIA
William D. Vacca, Ryan T. Hamilton, Maureen Savage +9
We present medium resolution near-infrared (NIR) spectra, covering 1.1 to 3.4 microns, of the normal Type Ia supernova (SN Ia) SN 2014J in M82 obtained with the FLITECAM instrument…
Spitzer/IRAC Observations of the Variability of Sgr A* and the Object G2 at 4.5 microns
J. L. Hora, G. Witzel, M. L. N. Ashby +9
We present the first detection from the Spitzer Space Telescope of 4.5 micron variability from Sgr A*, the emitting source associated with the Milky Way's central black hole. The >…
The Keplerian orbit of G2
L. Meyer, A. M. Ghez, G. Witzel +8
We give an update of the observations and analysis of G2 - the gaseous red emission-line object that is on a very eccentric orbit around the Galaxy's central black hole and predict…
