Relativistic Jets in Active Galactic Nuclei
Roger Blandford, David Meier, Anthony Readhead
The nuclei of most normal galaxies contain supermassive black holes, which can accrete gas through a disk and become active. These Active Galactic Nuclei, AGN, can form jets which…
Constraining the limiting brightness temperature and Doppler factors for the largest sample of radio bright blazars
I. Liodakis, T. Hovatta, D. Huppenkothen +3
Relativistic effects dominate the emission of blazar jets complicating our understanding of their intrinsic properties. Although many methods have been proposed to account for them…
The extreme HBL behaviour of Markarian 501 during 2012
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +276
A multiwavelength campaign was organized to take place between March and July of 2012. Excellent temporal coverage was obtained with more than 25 instruments, including the MAGIC,…
Multi-wavelength characterization of the blazar S5~0716+714 during an unprecedented outburst phase
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +187
The BL Lac object S5~0716+714, a highly variable blazar, underwent an impressive outburst in January 2015 (Phase A), followed by minor activity in February (Phase B). The MAGIC obs…
