Description
The gamma-ray blazar TXS 0506+056 was discovered in very high energy (>100 GeV) gamma-rays by the MAGIC telescopes in 2017 in a coincidence with a high energy neutrino event IC-170922A. Subsequent multiwavelength (MWL) observations and theoretical modeling suggest that this source could be a cosmic ray and neutrino emitter. So far, this is the most significant association between a high-energy neutrino and an astrophysical source emitting gamma rays and X-rays. Through accurate and contemporaneous MWL spectral measurements of TXS 0506+056, we can test the connection between the high-energy neutrinos and blazars. We present the light curves and simultaneous spectral energy distributions from the MAGIC and MWL monitoring of this source, from November 2017 till February 2019, together with the theoretical interpretation of these observations. We discuss their implications on cosmic-ray accelerations in AGN and on the physics of relativistic jets from supermassive black holes.
