Pinpointing the location of the gamma-ray emitting region in the FSRQ 4C+01.28
F. Rösch, M. Kadler, E. Ros +5
The FSRQ 4C+01.28 is a bright and highly variable radio and -ray emitter. We aim to pinpoint the location of the -ray emitting region within its jet in order to derive stro…

A gamma-ray flare from TXS 1508+572: characterizing the jet of a blazar in the early Universe
Andrea Gokus, Markus Böttcher, Manel Errando +13
Blazars can be detected from very large distances due to their high luminosity. However, the detection of -ray emission of blazars beyond has only been confirmed for a sm…
