In this work we investigate a scenario where the dark matter of the universe is made of light hidden photons. Thanks to a $Z_{2}$ symmetry, the kinetic mixing with the photon is forbidden and the dark photon interacts with the Standard Model only via an axion-like particle, that acts as a messenger. Focusing on signatures involving the ordinary photon, our survey of the phenomenology includes...

In the summer of 2021, construction of the COSINUS experiment will begin at the Laboratori Nazionali del Gran Sasso in Italy. COSINUS (Cryogenic Observatory for SIgnatures seen in Next-generation Underground Searches) is a direct dark matter search experiment specifically designed to cross-check the signal reported by the DAMA/LIBRA collaboration since many years. Featuring high-purity...

DMRadio, which now includes the ABRACADABRA collaboration, is a multi-detector program to search for axion dark matter (aDM) with mass below 1 𝜇eV using a lumped-element resonator. DMRadio-50L is a toroidal detector that will probe aDM over the range 20 peV$\lt m_a\lt $ 20 neV down to photon couplings of $g_{a\gamma\gamma} > 5\times10^{-15}\,\mathrm{GeV}^{-1}$. It is currently under...

We investigate the potential of core-collapse supernovae (SNe) to constrain axion-like particles (ALPs) coupled to nucleons and electrons. ALPs coupled to nucleons can be efficiently produced in the SN core via nucleon-nucleon bremsstrahlung and, for a wide range of parameters, leave the SN unhindered producing a large ALP flux. For ALP masses exceeding 1 MeV, these ALPs would decay into...
