During the last decade a third window for ground-based astronomy was opened and high energy astrophysics now enables studies up to photon energies of 100 TeV. A wide range of objects were discovered to emit significant amounts of energy in the high-energy gamma-ray regime, including star-forming regions, pulsars, supernova remnants, massive binaries, the diffuse interstellar medium, the Galactic Centre, AGN, etc. ...

... Seminar archive . ... The structure of the X-ray sources in the hard spectral state of accreting black-hole binaries has been a subject of intense debate. The paradigm dominant for many years postulated that the accretion disc in the hard state is truncated at some radius >> the innermost stable orbit (ISCO) whereas the disc reaches the ISCO in the soft state. ... On the other hand, there have been numerous claims in recent years that the disc extends to the ISCO in the hard state. ...
