A Transient Search with IceCube-DeepCore

ORAL

Abstract

A time-dependent flux of TeV neutrinos was recently discovered originating from the direction of the blazar TXS 0506+056 using the IceCube Neutrino Observatory. Additional events may be observable by IceCube at lower energies, although the existing analysis rapidly loses sensitivity below about 1 TeV. The densely instrumented DeepCore sub-array provides the ability to reduce the threshold for observation from 1 TeV down to approximately 10 GeV. This energy range, often ignored due to large backgrounds from conventional atmospheric neutrinos, can provide a unique window to probing low energy transient astrophysical fluxes. Using a newly developed sample, an analysis to search for astrophysical sources using these low energy transient sources will be presented.
