Impact of galactic distributions in celestial capture of dark matter

Understand

Celestial capture of dark matter provides a useful handle for constraining its particulate properties.

• The capture formalism is sensitive to the phase space distribution of dark matter in the vicinity of the celestial object.
• This article aims to systematically study the impact of uncertainties and the influence of cosmological simulations on the rate at which dark matter particles are captured inside a variety of celestial objects.
• Going beyond the framework of the Maxwell-Boltzmann distribution or the standard halo model, we take up pragmatic dark matter velocity distributions motivated by observations or cosmological simulations.
