In 2012 the IceCube detector observed the first clear detection of a diffuse astrophysical high energy
neutrino flux, however, the sources for these neutrinos have yet to be found. Hadronic interactions around
cosmic ray accelerators result in both high energy gamma and neutrino fluxes from the decay of neutral
and charged pion respectively.
Observing gamma ray sources with neutrinos provides unique evidence of the hadronic nature of these
sources. These searches involve looking for a significant clustering of neutrinos from any
direction or a correlation with a known source observed by other messengers also expected to emit a neutrino
flux. These searches range from stacking populations of similar sources such as active galactic
nuclei, to time-dependent searches targeting individual sources when they are in flaring states. We present here
the most recent updates in the search for sources of extraterrestrial neutrinos using the latest methods and
source information.
