Sub-GeV Dark Matter and X-rays

(1) , (2) , (3) , (1, 2)


We present bounds on Dark Matter (DM) in the MeV to GeV mass range, obtained by using X-ray measurements from the I telescope. A crucial element, that allows us to derived bounds competitive or stronger than existing ones from other techniques, resides in the inclusion of the contribution from inverse Compton scattering on galactic radiation fields and on the CMB. This contribution is based on [1], to which we refer for additional details.
