Radio Imaging of the Very-High-Energy Gamma-Ray Emission Region in the Central Engine of a Radio Galaxy

The VERITAS Collaboration, the VLBA 43 GHz M 87 Monitoring Team, the H. E. S. S. Collaboration +1

The accretion of matter onto a massive black hole is believed to feed the relativistic plasma jets found in many active galactic nuclei (AGN). Although some AGN accelerate particle…

Monitoring of bright blazars with MAGIC telescope

C. C. Hsu, K. Satalecka, M. Thom +9

Blazars, a class of Active Galactic Nuclei (AGN) characterized by a close orientation of their relativistic outflows (jets) towards the line of sight, are a well established extrag…

Monitoring of Bright Blazars with MAGIC in the 2007/2008 Season

Konstancja Satalecka, Ching-Cheng Hsu, Elisa Bernardini +7

Because of the short duty-cycles and observation-time constraints, studies of bright TeV (E>100 GeV) blazars are mostly restricted to flaring episodes or rather short (days to few…
