Searching for Dark Matter with circularly polarised photons from the Galactic Centre
Marina Cermeño, Céline Degrande, Luca Mantani
Conventional indirect dark matter (DM) searches look for an excess in the electromagnetic emission from the sky that cannot be attributed to known astrophysical sources, but its po…
Medium effects in supernovae constraints on light mediators
David G. Cerdeño, Marina Cermeño, M. Ángeles Pérez-García +1
In this article, we reevaluate supernovae (SN) constraints on the diffusion time of neutrinos for a family of extensions of the Standard Model that incorporate new light scalar and…
Modified Gravity at Astrophysical Scales
M. Cermeño, J. Carro, A. L. Maroto +1
Using a perturbative approach we solve stellar structure equations for low-density (solar-type) stars whose interior is described with a polytropic equation of state in scenarios i…
Gamma rays from dark mediators in white dwarfs
M. Cermeño, M. Angeles Pérez-García
We consider self-annihilation of dark matter, , into metastable mediators, , and their subsequent decay into photons inside white dwarfs. We focus on reactions of the type $χ…
Fermionic Light Dark Matter particles and the New Physics of Neutron Stars
M. Cermeño, M. Ángeles Pérez-García, Joseph Silk
Dark Matter constitutes most of the matter in the presently accepted cosmological model for our Universe. The extreme conditions of ordinary baryonic matter, namely high density an…
