Search for steady point-like sources in the astrophysical muon neutrino flux with 8 years of IceCube data

Understand

The IceCube Collaboration has observed a high-energy astrophysical neutrino flux and recently found evidence for neutrino emission from the blazar TXS 0506+056.

• These results open a new window into the high-energy universe.
• However, the source or sources of most of the observed flux of astrophysical neutrinos remains uncertain.
• Here, a search for steady point-like neutrino sources is performed using an unbinned likelihood analysis.
