The 3 Ms Chandra Campaign on Sgr A*: A Census of X-ray Flaring Activity from the Galactic Center
J. Neilsen, M. A. Nowak, C. Gammie +14
Over the last decade, X-ray observations of Sgr A* have revealed a black hole in a deep sleep, punctuated roughly once per day by brief flares. The extreme X-ray faintness of this…
A Chandra/HETGS Census of X-ray Variability From Sgr A* During 2012
J. Neilsen, M. A. Nowak, C. Gammie +13
We present the first systematic analysis of the X-ray variability of Sgr A* during the Chandra X-ray Observatory's 2012 Sgr A* X-ray Visionary Project (XVP). With 38 High Energy Tr…
Tilted black hole accretion disc models of Sagittarius A*: time-variable millimetre to near-infrared emission
Jason Dexter, P. Chris Fragile
High-resolution, multi-wavelength, and time-domain observations of the Galactic centre black hole candidate, Sgr A*, allow for a direct test of contemporary accretion theory. To da…
Observational Signatures of Tilted Black Hole Accretion Disks from Simulations
Jason Dexter, P. Chris Fragile
Geometrically thick accretion flows may be present in black hole X-ray binaries observed in the low/hard state and in low-luminosity active galactic nuclei. Unlike in geometrically…
