Strong Constraints on Line Signals from Dark Matter Annihilation in a Nearby Subhalo

Asier Salces Pérez, Thong T. Q. Nguyen, Pedro De la Torre Luque +1

We present a dedicated search for monochromatic gamma-ray emission from a recently proposed nearby dark matter subhalo candidate. Using nearly 15 years of Fermi-LAT Pass 8 data, we…

Galactic cold clouds constraints on sub-GeV DM and asteroid-mass PBHs

Asier Salces Pérez, Pedro de la Torre Luque

We show that the ionization of molecular and atomic clouds provides a novel probe of dark matter scenarios producing low-energy $e^{+} e^{-}$ pairs through annihilation, decay, or Hawki…
