Infrared Line Diagnostics Fail to Constrain Sgr A*'s UV Output
Mayura Balakrishnan, Sebastiano D. von Fellenberg, Daryl Haggard +11
Sgr A*, the 4 x supermassive black hole at the Galactic Center, exhibits frequent flaring with X-ray luminosities of erg s, while i…
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…
Light and shadow in the Galactic Center - On the detection of the relativistic periastron shift of star S2 in the Galactic Center
A. Eckart, M. Parsa, E. Mossoux +11
We report on the nature of prominent sources of light and shadow in the Galactic Center. With respect to the Bremsstrahlung X-ray emission of the hot plasma in that region the Gala…
The Multifrequency Behavior of Sagittarius A*
A. Eckart, M. Zajacek, M. Parsa +15
The Galactic Center is the closest galactic nucleus that allows us to determine the multi-frequency behavior of the supermassive black hole counterpart Sagittarius A* in great deta…
Source-intrinsic near-infrared properties of Sgr A*: Total intensity measurements
G. Witzel, A. Eckart, M. Bremer +12
We present a comprehensive data description for Ks-band measurements of Sgr A*. We characterize the statistical properties of the variability of Sgr A* in the near-infrared, which…
Near-infrared polarimetry as a tool for testing properties of accreting super-massive black holes
M. Zamaninasab, A. Eckart, M. Dovciak +10
Several massive black holes exhibit flux variability on time scales that correspond to source sizes of the order of few Schwarzschild radii. We survey the potential of near-infrare…
