A further look at particle annihilation in dark matter caustics

TL;DR

This paper explores the potential detection of dark matter caustics through gamma-ray signals resulting from particle annihilation, providing sky maps of expected gamma ray distributions.

Contribution

It analyzes particle annihilation in dark matter caustics and offers detailed sky maps of gamma ray emissions, advancing detection strategies.

Findings

Gamma ray signals from dark matter caustics are theoretically modeled.

Sky maps of gamma ray distribution are provided for observational guidance.

Dark matter annihilation in caustics could be detectable with current or future gamma-ray telescopes.

Abstract

Dark matter caustics are small scale, high density structures believed to exist in galaxies like ours. If the dark matter consists of Weakly Interacting Massive Particles, these caustics may be detected by means of the gamma rays produced by dark matter particle annihilation. We discuss particle annihilation in outer and inner caustics and provide sky maps of the expected gamma ray distribution.
