Multi-messenger Astronomy with IceCube Neutrinos
Anna Franckowiak (Humboldt University, Berlin)
Description :

The recent discovery of high-energy astrophysical neutrinos has opened a new window to the Universe. Identifying the sources of those neutrinos is the most pressing question in the new field of neutrino astronomy. Combining neutrino data with electromagnetic measurements in a multi-messenger approach increases the sensitivity to identify the neutrino sources and helps to solve long-standing problems in astrophysics such as the origin of cosmic rays.

A first compelling candidate was identified on September 22, 2017, when the IceCube Neutrino Observatory observed an extremely high-energy neutrino, IceCube-170922, in spatial and temporal coincidence with a gamma-ray flaring blazar, TXS 0506+056, monitored by the Fermi Large Area Telescope. The coincidence triggered a large follow-up campaign in a broad wavelength band.

In this talk I will review the recent progress in multi-messenger astronomy using neutrino data with a focus on the candidate source, TXS 0506+056.


Anna Franckowiak is researcher in DESY in the IceCube collaboration specialized on the multi-messenger astronomy. She is involved since a long time in the electromagnetic follow-up of the high-energy neutrinos. She had also a leading role in the neutrino association with TXS 0506+056.
