Searching for dark matter X-ray lines from the Large Magellanic Cloud with eROSITA
Jorge Terol Calvo, Marco Taoso, Andrea Caputo +2
We perform a search for an X-ray monochromatic line arising from dark matter (DM) decay in the halo of the Large Magellanic Cloud. An emission line can be expected from two well-mo…

The Heavy Dark Photon Handbook: Cosmological and Astrophysical Bounds
Andrea Caputo, Jaeyoung Park, Seokhoon Yun
We investigate cosmological and astrophysical constraints on dark photons with masses - MeV. These dark photons can be copiously produced either in the early un…

Cooling the Shock: New Supernova Constraints on Dark Photons
Andrea Caputo, Hans-Thomas Janka, Georg Raffelt +1
During the accretion phase of a core-collapse supernova (SN), dark-photon (DP) cooling can be largest in the gain layer below the stalled shock wave. In this way, it could counter-…
