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 >…
A formal method for identifying distinct states of variability in time-varying sources: SgrA* as an example
L. Meyer, G. Witzel, F. A. Longstaff +1
Continuously time variable sources are often characterized by their power spectral density and flux distribution. These quantities can undergo dramatic changes over time if the und…
Modeling mm- to X-ray flare emission from SgrA*
A. Eckart, F. K. Baganoff, M. R. Morris +17
We report on new modeling results based on the mm- to X-ray emission of the SgrA* counterpart associated with the massive black hole at the Galactic Center. Our modeling is based o…
Coordinated mm/sub-mm observations of Sagittarius A* in May 2007
D. Kunneriath, A. Eckart, S. Vogel +26
At the center of the Milky Way, with a distance of ~8 kpc, the compact source Sagittarius A* (SgrA*) can be associated with a super massive black hole of ~4x10^6 solar masses. SgrA…
An evolving hot spot orbiting around Sgr A*
M. Zamaninasab, A. Eckart, L. Meyer +9
Here we report on recent near-infrared observations of the Sgr A* counterpart associated with the super-massive ~ 4x10^6 M_sun black hole at the Galactic Center. We find that the M…
