Sgr A* in context: daily flares as a probe of the fundamental X-ray emission process in accreting black holes
Sera Markoff
Our central Galactic supermassive black hole, Sgr A*, exists mostly in a very stable, extremely low-luminosity (~10^{-9} L_Edd), thermal quiescent state, which is interrupted rough…
Exploring the Jet/Accretion Flow Relationship in Low Disk Luminosity Sources
Sera Markoff
Astrophysical jets seem to gain strength disproportionate to the power of their associated accretion flow, making low-luminosity sources ideal targets for studies of the role of ou…
Long term variability of Cygnus X-1, III. Radio-X-ray correlations
T. Gleissner, J. Wilms, G. G. Pooley +7
Long time scale radio-X-ray correlations in black holes during the hard state have been found in many sources and there seems to emerge a universal underlying relationship which qu…
Constraining X-ray Binary Jet Models via Reflection
Sera Markoff, Michael A. Nowak
Although thermal disk emission is suppressed or absent in the hard state of X-ray binaries, the presence of a cold, thin disk can be inferred from signatures of reprocessing in the…
Further Clues to the Nature of Composite LINER/HII Galaxies
M. E. Filho, F. Fraternali, S. Markoff +4
We have analyzed new, archival and published high resolution radio and X-ray observations of a sample of composite LINER/HII galaxies known to exhibit AGN-like properties. Five of…
