Scientists have tested the hypothesis of blazars as sources of high-energy neutrinos
Researchers from St Petersburg University, the Institute of Astrophysics (FORTH) and the University of Crete analyzeddata from the Fermi space gamma-ray observatory and the IceCube neutrinoobservatory and confirmed the theoretically predicted possibility that the radial jetstructure of blazars contributes to the formation of neutrinos in them. Massive black holes, whose mass exceeds millions of solar …

B2 1420+32 is in high optical and polarization state
Astronomer’s Telegram #14819 S. S. Savchenko, M. I. Chazov, A. E. Nazarova, E. V. Shishkina, E. G. Larionova We perform optical photometric and polarimetric monitoring of a sample of gamma-bright blazars using 0.7-m AZT-8 telescope (Crimean Astrophysical Observatory), within the frames of GASP/WEBT project. We report that the blazar B21420+32 (z=0.681) is active in optical, …
