Muonic Boson Limits: Supernova Redux
Andrea Caputo, Georg Raffelt, Edoardo Vitagliano
We derive supernova (SN) bounds on muon-philic bosons, taking advantage of the recent emergence of muonic SN models. Our main innovations are to consider scalars in addition to…
Dark photon limits: a handbook
Andrea Caputo, Alexander J. Millar, Ciaran A. J. O'Hare +1
The dark photon is a massive hypothetical particle that interacts with the Standard Model by kinetically mixing with the visible photon. For small values of the mixing parameter, d…
Axion-like Particles from Hypernovae
Andrea Caputo, Pierluca Carenza, Giuseppe Lucente +5
It was recently pointed out that very energetic subclasses of supernovae (SNe), like hypernovae and superluminous SNe, might host ultra-strong magnetic fields in their core. Such f…
Detecting the radiative decay of the cosmic neutrino background with line-intensity mapping
José Luis Bernal, Andrea Caputo, Francisco Villaescusa-Navarro +1
We study the possibility to use line-intensity mapping (LIM) to seek photons from the radiative decay of neutrinos in the cosmic neutrino background. The Standard Model prediction…
Electromagnetic Signatures of Dark Photon Superradiance
Andrea Caputo, Samuel J. Witte, Diego Blas +1
Black hole superradiance is a powerful tool in the search for ultra-light bosons. Constraints on the existence of such particles have been derived from the observation of highly sp…
