Title: Multi-messenger observations of a flaring blazar coincident with high-energy neutrino IceCube-170922AAuthors: The IceCube, Fermi-LAT, MAGIC, AGILE, ASAS-SN, HAWC, H.E.S.S., INTEGRAL, Kanata, Kiso, Kapteyn, Liverpool Telescope, Subaru, Swift/NuSTAR, VERITAS, and VLA/17B-403 teamsStatus: Published in Science.
Multiple Astrobites over the years have focused on papers exploring the mysterious origin of IceCube’s astrophysical neutrinos. The first detection of astrophysical neutrinos in 2013 inspired significant effort towards identifying their progenitors. To aid in the rapid multi-messenger followup of their highest energy neutrinos, a real-time alert program was set up to immediately notify the community and allow astronomers around the world to possibly identify the sources of these neutrinos. As of September 2017, nine such real-time alerts had been distributed to the general astrophysical community; none resulted in the detection of an electromagnetic counterpart.

That was until September 22, 2017, when a high energy astrophysical neutrino (IC170922) zipped through the cold Antarctic ice. However, unlike the many millions of its brethren who zoomed right on through and out the other side of the Earth, continuing their journey through space, this neutrino collided with an atomic nucleus deep in the ice near the IceCube Neutrino Observatory located at the South Pole. This interaction ...
