Neutron Stars as a Probe of Cosmic Neutrino Background
Garv Chauhan

TL;DR
This paper explores how neutron stars could serve as natural detectors for the elusive cosmic neutrino background by analyzing neutrino scattering effects on neutron star cooling and potential detection methods.
Contribution
It introduces a novel approach to probe the cosmic neutrino background using neutron star cooling and discusses the implications of new physics scenarios on this method.
Findings
Neutrino scattering can enhance neutron star cooling in dense environments.
Detection prospects are limited but can constrain overdensities on small scales.
Long-range forces could significantly affect neutron star cooling via the cosmic neutrino background.
Abstract
The Cosmic Neutrino Background (CB) constitutes the last observable prediction of the standard cosmological model, which has yet to be detected directly. In this work, we show how the coherent scattering of neutrinos off dense neutron matter can lead to an additional cooling channel in neutron stars (NSs). We also include the effects of gravitational capture and boosting, but find that the cooling is efficient only in the presence of large overdensities. We further discuss the prediction of a boosted CB flux on Earth from nearby NSs and the potential detection prospects in the case of a future nearby galactic supernova. Although currently these ideas do not offer any detection prospects, they can be used to constrain overdensities on short length scales . We also discuss the impact of new physics scenarios,…
