Constraints from the duration of supernova neutrino burst on on-shell light gauge boson production by neutrinos
David G. Cerdeño, Marina Cermeño, Yasaman Farzan
In this article, we study the on-shell production of low-mass vector mediators from neutrino-antineutrino coalescence in the core of proto-neutron stars. Taking into account the ra…
Signatures of leptophilic t-channel dark matter from active galactic nuclei
Marina Cermeño, Céline Degrande, Luca Mantani
In this work, we study indirect photon signatures of leptophilic dark matter (DM) coming from Centaurus A, where a DM density spike is believed to have survived to date contrary to…
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…
Circular polarisation of gamma rays as a probe of dark matter interactions with cosmic ray electrons
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. Here, we a…
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…
Science with e-ASTROGAM (A space mission for MeV-GeV gamma-ray astrophysics)
A. De Angelis, V. Tatischeff, I. A. Grenier +248
e-ASTROGAM (enhanced ASTROGAM) is a breakthrough Observatory space mission, with a detector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated t…
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…
Enhanced neutrino emissivities in pseudoscalar-mediated Dark Matter annihilation in Neutron Stars
M. Cermeño, M. A. Pérez-García, R. A. Lineros
We calculate neutrino emissivities from self-annihilating dark matter () in the dense and hot stellar interior of a (proto)neutron star. Using a model where dark matter interact…
Light dark matter scattering in outer neutron star crusts
Marina Cermeño, M. Ángeles Pérez-García, Joseph Silk
We calculate for the first time the phonon excitation rate in the outer crust of a neutron star due to scattering from light dark matter (LDM) particles gravitationally boosted int…
Diffusion of dark matter in a hot and dense nuclear environment
Marina Cermeño, M. Ángeles Pérez-García, Joseph Silk
We calculate the mean free path in a hot and dense nuclear environment for a fermionic dark matter particle candidate in the GeV mass range interacting with nucleons via scal…
