Looking to the future: using IR interferometry to study microquasars
Sera Markoff
Infrared interferometry is currently in a rapid development phase, with new instrumentation soon achieving milliarcsecond spatial resolutions for faint sources and astrometry on th…
Catching Up on State Transitions in Cygnus X-1
Moritz Boeck, Manfred Hanke, Joern Wilms +6
In 2005 February we observed Cygnus X-1 over a period of 10 days quasi-continuously with the Rossi X-ray Timing Explorer and the Ryle telescope. We present the results of the spect…
Results from an extensive simultaneous broadband campaign on the underluminous active nucleus M81*: further evidence for mass-scaling accretion in black holes
S. Markoff, M. Nowak, A. Young +13
We present the results of a broadband simultaneous campaign on the nearby low-luminosity active galactic nucleus M81*. From February through August 2005, we observed M81* five time…
Broadband X-ray Spectra of GX 339-4 and the Geometry of Accreting Black Holes in the Hard State
John A. Tomsick, Emrah Kalemci, Philip Kaaret +6
A major question in the study of black hole binaries involves our understanding of the accretion geometry when the sources are in the hard state. In this state, the X-ray energy sp…
