Uncertainties in measuring the dark matter signal from Milky Way satellites using Cherenkov telescopes
Journal of Cosmology and Astroparticle Physics(2023)
摘要
In this work, we present a modelling of the galactic sub-clumps based on statis-tical estimations of the full Milky Way satellite population. We introduce 10 substructure modellings (SMi, i E {1, ... ,10}) with the following varying parameters: a) subhalos inner profile, b) spatial distribution of subhalos, c) mass distribution of subhalos, d) total number of subhalos and e) concentration parameter. The sensitivity curves of CTA for sources in each model are calculated for the 7+- and bb over bar decay channels. With both detection of a signal (5o-) with the CTA and no signal observation, no model was effective in accessing the thermal values of (o -v). We analyse the systematic effect introduced by the substructures models.
