Hubble constant and nuclear equation of state from kilonova spectro-photometric light curves
M. A. Pérez-García, L. Izzo, D. Barba +17
The merger of two compact objects of which at least one is a neutron star is signalled by transient electromagnetic emission in a kilonova (KN). This event is accompanied by gravit…
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…
Neutron Stars Mass-Radius relationship and Electromagnetic follow-up of Kilonovae
D. Barba-González, M. Ángeles Pérez-García
When two Neutron Stars collide a multi-band electromagnetic emission, known as Kilonova (KN), follows being powered by the radioactive decay of ejecta products. In this contributio…
Neutron stars as probes of dark matter
M. Ángeles Pérez-García, J. Silk
Neutron Stars (NSs) are compact stellar objects that are stable solutions in General Relativity. Their internal structure is usually described using an equation of state that invol…
Weak B Decays into Orbitally Excited Charmed Mesons
J. Segovia, C. Albertus, D. R. Entem +3
The BaBar Collaboration has recently reported branching fractions for semileptonic decays of the meson into final states with charged and neutral and $D_{2}^{\ast…
Dark matter and bubble nucleation in old neutron stars
A. Herrero, M. A. Pérez-García, J. Silk +1
We study the probability for nucleation of quark matter droplets in the dense cold cores of old neutron stars induced by the presence of a self-annihilating dark matter component,…
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…
Heavy sterile neutrinos in stellar core-collapse
Tomasz Rembiasz, Martin Obergaulinger, Manuel Masip +3
We perform spherically symmetric simulations of the core collapse of a single progenitor star of zero age main sequence mass with two models of hea…
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…
Production of unstable heavy neutrinos in proto-neutron stars
C. Albertus, M. Masip, M. A. Pérez-García
We discuss the production of a class of heavy sterile neutrinos in proto-neutron stars. The neutrinos, of mass around MeV, have a negligible mixing with the active speci…
Magnetic susceptibility and magnetization properties of asymmetric nuclear matter under a strong magnetic field
A. Rabhi, M. A. Pérez-García, C. Providência +1
We study the effect of a strong magnetic field on the proton and neutron spin polarization and magnetic susceptibility of asymmetric nuclear matter within a relativistic mean-field…
GAMMA-LIGHT: High-Energy Astrophysics above 10 MeV
Aldo Morselli, Andrea Argan, Guido Barbiellini +39
High-energy phenomena in the cosmos, and in particular processes leading to the emission of gamma- rays in the energy range 10 MeV - 100 GeV, play a very special role in the unders…
Semileptonic and decays into orbitally excited charmed mesons
J. Segovia, C. Albertus, D. R. Entem +3
The BaBar Collaboration has recently reported products of branching fractions that include meson semileptonic decays into final states with charged and neutral an…
Dynamical response of the nuclear pasta in neutron star crusts
C. J. Horowitz, M. A. Pérez-García, D. K. Berry +1
The nuclear pasta -- a novel state of matter having nucleons arranged in a variety of complex shapes -- is expected to be found in the crust of neutron stars and in core-collapse s…
