Exploring the case for hard-X-ray beaming in NGC 6946 X-1
Tobias Beuchert, Matthew J. Middleton, Roberto Soria +5
In order to understand the nature of super-Eddington accretion we must explore both the emission emerging directly from the inflow and its impact on the surroundings. In this paper…
Rapid Variability of Mrk 421 During Extreme Flaring as Seen Through the Eyes of XMM-Newton
A. Gokus, J. Wilms, M. Kadler +31
By studying the variability of blazars across the electromagnetic spectrum, it is possible to resolve the underlying processes responsible for rapid flux increases, so-called flare…
Potential origin of the state-dependent high-energy tail in the black hole microquasar Cygnus X-1 as seen with INTEGRAL
F. Cangemi, T. Beuchert, T. Siegert +8
0.1-10 MeV observations of the black hole microquasar Cygnus X-1 have shown the presence of a spectral feature in the form of a power law in addition to the standard black body and…
Sub-milliarcsecond imaging of a bright flare and ejection event in the extragalactic jet 3C 111
R. Schulz, M. Kadler, E. Ros +8
Flares in radio-loud AGN are thought to be associated with the injection of fresh plasma into the compact jet base. Such flares are usually strongest and appear earlier at shorter…
Long-term spectral study of the black hole Cygnus X-1 using INTEGRAL
F. Cangemi, T. Beuchert, T. Siegert +6
We utilize the joint capabilities of IBIS and SPI to perform a state-resolved 20--2000\,keV analysis of the microquasar Cygnus X-1. In both LHS and HSS, the spectral analysis revea…
The Soft-Excess in Mrk 509: Warm Corona or Relativistic Reflection?
Javier A. Garcia, Erin Kara, Dominic Walton +15
We present the analysis of the first NuSTAR observations ( ks), simultaneous with the last SUZAKU observations ( ks), of the active galactic nucleus of the brigh…
