AMON: TeV Gamma and TeV Neutrino Coincidence Alerts from HAWC and IceCube subthreshold data
POSTER
Abstract
Multimessenger astrophysics has become the next step to understand the high-energy astrophysical phenomena in the universe. Hints of possible detection of a gamma-ray and neutrino source were shown last year with the source TXS0506+056; however, more detections are needed. We present preliminary results on the generation of real-time (< 6 hours) TeV gamma-ray and neutrino multimessenger transient alerts with subthreshold data from the HAWC and IceCube Observatories via the Astrophysical
Multimessenger Observatory Network (AMON). The analysis is based on a likelihood ratio framework, yielding real-time AMON coincidence alerts for HAWC "hot spots" and IceCube neutrinos. These alerts will be distributed to AMON follow-up partners with a median anticipated delay of six hours from HAWC transit, will have an angular resolution of ∼ 0.2º, and will be well-suited for deep electromagnetic follow-up observations.
