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 COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Searching for axion-like particles with SPHEREx
Marco Regis, Marco Taoso, Jorge Terol Calvo
We study prospects to detect axion-like particles (ALPs) with the upcoming near-infrared telescope SPHEREx. The signal under investigation is the ALP decay into two photons. Assumi…
Bounds on Axions-Like Particles Shining in the Ultra-Violet
Elisa Todarello, Marco Regis
Axion-like particles (ALPs) can decay into two photons with a rest-frame frequency given by half of the ALP mass. This implies that ultra-violet searches can be used to investigate…
