Search for GeV-PeV neutrinos from nova T Coronae Borealis with IceCube
Jessie Thwaites, Justin Vandenbroucke (for the IceCube Collaboration)

TL;DR
This paper discusses a planned real-time search for neutrinos from the recurrent nova T Coronae Borealis using IceCube, leveraging its proximity and optical brightness to improve detection prospects over previous searches.
Contribution
It introduces a targeted follow-up strategy for T CrB with IceCube, aiming to detect neutrinos associated with its nova outburst, which is expected to produce a stronger signal than previous novae.
Findings
No neutrinos detected from previous novae
T CrB's closer distance increases detection likelihood
Enhanced sensitivity due to T CrB's position in the sky
Abstract
The widely anticipated outburst of recurrent nova T Coronae Borealis (T CrB), which is near the end of its 80-year cycle, provides an excellent opportunity to search for neutrinos from novae. Novae are an energetic class of transients, which have been studied for hundreds of years. Because many of them are located nearby, novae provide an excellent astrophysical laboratory to study shock-powered emission in our own backyard. Several recent novae have previously been detected in GeV gamma rays, and the 2021 outburst of RS Ophiuchi was detected up to TeV energies, with evidence for a hadronic origin of the observed emission. Previous searches for GeV-TeV neutrinos from novae, predicted to occur alongside their gamma-ray emission, have been performed using data from the IceCube Neutrino Observatory. However, no significant neutrino signals from novae have yet been observed. We present…
