TXS 0506+056 with Updated IceCube Data

Past results from the IceCube Collaboration have suggested that the blazar TXS 0506+056 is a potential source of astrophysical neutrinos. However, in the years since there have been numerous updates to event processing and reconstruction, as well as improvements to the statistical methods used to search for astrophysical neutrino sources. These improvements in combination with additional years of data have resulted in the identification of NGC 1068 as a second neutrino source candidate. This talk will re-examine neutrino emission from TXS 0506+056 using many of the techniques that were developed as part of the analysis of NGC 1068. Using these improved techniques, we calculate a new significance and flux fit for the 2014 TXS 0506+056 "untriggered" neutrino flare candidate that was originally identified in the 2017 IceCube analysis.
