Title: Dark Matter in Heavenly Bodies
Abstract:
Celestial objects can capture dark matter particles through their gravitational potentials. In such scenarios, dark matter can lose kinetic energy via scattering with nucleons and electrons within these objects, reducing its velocity below the local escape velocity. Once captured, dark matter particles may accumulate and subsequently annihilate, producing distinctive signals such as neutrinos and gamma rays. In this talk, I will discuss how observations of gamma rays and neutrinos can be used to probe the interactions between dark matter and Standard Model particles inside celestial bodies. I will also outline future directions of this research, highlighting its potential to bridge the gap between direct and indirect detection strategies for dark matter.
