Integral and Rxte/Asm Observations on Igr J17098-3628
Yu-Peng Chen, Shu Zhang, Nick Schurch +5
To probe further the possible nature of the unidentified source IGR J17098-3628, we have carried out a detailed analysis of its long-term time variability as monitored by RXTE/ASM,…
High energy properties of PKS 1830-211
Shu Zhang, Yu-peng Chen, Werner Collmar +4
We report on an analysis of X- and -ray observations of PKS 1830-211, based on the long-term campaigns carried out by \emph{INTEGRAL} and COMPTEL. The \emph{INTEGRAL} data curre…
Spins of the supermassive black hole in M87: new constraints from TeV observations
Jian-Min Wang, Yan-Rong Li, Jain-Cheng Li +1
The rapid TeV ray variability detected in the well-known nearby radio galaxy M87 implies an extremely compact emission region (5-10 Schwarzschild radii) near the horizon of the…
