Abstract content

In September 2017, the IceCube neutrino observatory revealed an event designated IceCube-170922A with a high probability of being of astrophysical origin. The event was detected in spatial coincidence with the BL Lac object TXS 0506+056 during a period of enhanced GeV gamma-ray activity. We monitored the object in the very-high-energy (VHE; E>100 GeV) band with the MAGIC telescopes, clearly detecting the object. This result marks the first time that VHE gamma rays have been measured from a direction consistent with a neutrino event. In this talk, we interpret MAGIC results on TXS 0506+056 in a multi-wavelength and multi-messenger context and we discuss some implications.
