OP 313, the blazar roars again – Media INAF

On January 14, the Magic telescopes detected a very high-energy gamma-ray flare from a source called OP 313. On January 28, it happened again. The estimated flux is above 80 GeV and has reached a level comparable to that of the Crab Nebula. Media Inaf interviewed our researcher Giacomo Bonnoli who helped coordinate the observation campaign – Read the full story on Media INAF

A composite image of the radio galaxy Hercules A, with the radio image obtained by Vla (New Mexico, USA) superimposed on the field photographed in optical by the orbiting Hubble Space Telescope. The optical image of the host galaxy is clearly visible in the center, and the two collimated radio jets emerging from the nuclear region. Blazars are sources of this type but fortuitously oriented with the axis of the relativistic jet in a direction close, within a few degrees, to the line of sight. Credits: NASA, ESA, S. Baum and C.
