General Relativistic effects and the NIR variability of Sgr A* II: A systematic approach to temporal asymmetry
Sebastiano D. von Fellenberg, Gunther Witzel, Michi Bauboeck +20
A systematic study, based on the third-moment structure function, of Sgr A*'s variability finds an exponential rise time and de…
Sgr A* near-infrared flares from reconnection events in a magnetically arrested disc
J. Dexter, A. Tchekhovskoy, A. Jiménez-Rosales +14
Large-amplitude Sgr A* near-infrared flares result from energy injection into electrons near the black hole event horizon. Astrometry data show continuous rotation of the emission…
A powerful flare from Sgr A* confirms the synchrotron nature of the X-ray emission
G. Ponti, E. George, S. Scaringi +21
We present the first fully simultaneous fits to the NIR and X-ray spectral slope (and its evolution) during a very bright flare from Sgr A*, the supermassive black hole at the Milk…
An Inverse Compton Scattering Origin of X-ray Flares from Sgr A*
F. Yusef-Zadeh, M. Wardle, K. Dodds-Eden +6
The X-ray and near-IR emission from Sgr A* is dominated by flaring, while a quiescent component dominates the emission at radio and sub-mm wavelengths. The spectral energy distribu…
Soft gamma-ray constraints on a bright flare from the Galactic Center supermassive black hole
G. Trap, A. Goldwurm, R. Terrier +11
Sagittarius A* (Sgr A*) is the supermassive black hole residing at the center of the Milky Way. It has been the main target of an extensive multiwavelength campaign we carried out…
