Testing the inverse-Compton catastrophe scenario in the intra-day variable blazar S5 0716+71, III. Rapid and correlated flux density variability from radio to sub-mm bands
L. Fuhrmann, T. P. Krichbaum, A. Witzel +22
The BL Lac object S5 0716+71 was observed in a global multi-frequency campaign to search for rapid and correlated flux density variability and signatures of an inverse-Compton (IC)…
A transient radio jet in an erupting dwarf nova
Elmar Koerding, Michael Rupen, Christian Knigge +4
Astrophysical jets seem to occur in nearly all types of accreting objects: from supermassive black holes to young stellar objects. Based on X-ray binaries, a unified scenario descr…
Studying the X-ray hysteresis in GX 339-4: the disc and iron line over one decade
R. J. H. Dunn, R. P. Fender, E. G. Koerding +2
We report on a comprehensive and consistent investigation into the X-ray emission from GX 339-4. All public observations in the 11 year RXTE archive were analysed. Three different…
Testing the inverse-Compton catastrophe scenario in the intra-day variable blazar S5 0716+71. I. Simultaneous broadband observations during November 2003
L. Ostorero, S. J. Wagner, J. Gracia +6
Some intra-day variable, compact extra-galactic radio sources show brightness temperatures severely exceeding 10^{12} K, the limit set by catastrophic inverse-Compton (IC) cooling…
Why the fundamental plane of black hole activity is not simply a distance driven artifact
A. Merloni, E. Koerding, S. Heinz +3
The fundamental plane of black hole activity is a non-linear correlation among radio core luminosity, X-ray luminosity and mass of all accreting black holes, both of stellar mass a…
A Radio Monitoring Survey of Ultra-Luminous X-Ray Sources
E. Koerding, E. Colbert, H. Falcke
We present the results of a radio monitoring campaign to search for radio emission from nearby ultra-luminous X-ray sources (ULXs). These sources are bright off-nuclear X-ray point…
