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…
General relativistic MHD simulations of non-thermal flaring in Sagittarius A*
Koushik Chatterjee, Sera Markoff, Joseph Neilsen +10
Sagittarius A* exhibits regular variability in its multiwavelength emission, including daily X-ray flares and roughly continuous near-infrared (NIR) flickering. The origin of this…
Kinematic Structure of the Galactic Center S-cluster
Basel Ali, Daria Paul, Andreas Eckart +7
We present a detailed analysis of the kinematics of 112 stars that mostly comprise the high velocity S-cluster and orbit the super massive black hole SgrA* at the center of the Mil…
