KM3NeT/ARCA expectations in view of a novel multimessenger study of starburst galaxies

TL;DR

This paper evaluates the potential of the KM3NeT/ARCA telescope to detect high-energy neutrinos from starburst galaxies, which are promising sources of cosmic rays and neutrinos, through a novel multimessenger approach.

Contribution

It presents the first detailed sensitivity analysis of KM3NeT/ARCA for neutrino detection from starburst galaxies across a wide energy range.

Findings

Sensitivity varies with different starburst galaxy scenarios.

KM3NeT/ARCA can detect neutrino signals from starburst galaxies within certain models.

The study highlights the potential of multimessenger observations for understanding cosmic ray sources.

Abstract

Starburst galaxies (SBGs) and more in general starforming galaxies represent a class of galaxies with a high star formation rate (up to 100 solar masses/year). Despite their low luminosity, they can 19 be considered as guaranteed "factories" of high energy neutrinos, being "reservoirs" of accelerated 20 cosmic rays and hosting a high density target gas in the central region. In this contribution 21 we present a novel multimessenger study of these sources and the possibility of observing their 22 neutrino signals with the KM3NeT/ARCA telescope. The differential sensitivity for different SBG 23 scenarios is reported considering track-like neutrino events in the 100 GeV-100 PeV energy range.
