Resonant Axion-Photon Conversion in the Early Inspiral of Neutron Star Binaries
D. Suárez-Fontanella, M. Ãngeles Pérez-GarcÃa, C. Albertus
We consider the early binary neutron star inspiral phase as a scenario to probe environmental axion--photon resonant conversion. For this we approximately model the merger site ele…

Probing ALP-photon couplings in Neutron Stars: Scalar versus pseudoscalar cases
D. Suárez-Fontanella, C. Albertus, M. Ãngeles Pérez-GarcÃa
We investigate the distribution of an interacting axion-like massive field within a magnetized Neutron Star. For this we consider the effect of an intense density-dependent axially…

Gravitational Wave emission in Binary Neutron Star early post-merger within a dark environment
D. Suárez-Fontanella, D. Barba-González, C. Albertus +1
Using an effective Lagrangian model inspired by Takami et al. 2015 we qualitatively study the early post-merger of a nearly symmetric binary Neutron Star (BNS) merger event with a…
