First detection of VHE gamma-ray signal from the FSRQ TON 0599
MAGIC Collaboration, K. Abe, S. Abe +245
TON\,0599 (z=0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, \,GeV) gamma-ray band. Its redshift makes it currently o…

MAD accretion and AGN jets -- an observational perspective
Tuomas Savolainen, Wara Chamani
One of the major open questions related to the production of jets by accreting black holes is: why do sources with similar accretion powers produce so vastly different jet powers?…

The polarisation behaviour of OJ 287 viewed through radio, millimetre and optical observations between 2015 and 2017
J. Jormanainen, T. Hovatta, E. Lindfors +13
OJ 287 is a bright blazar with century-long observations, and one of the strongest candidates to host a supermassive black hole binary. Its polarisation behaviour between 2015 and…
