DOI: 10.1093/mnras/stab2388
Abstract: A significant fraction of binary neutron star mergers occur in star-forming galaxies where the UV-optical and soft X-ray emission from the relativistic jet may be absorbed by dust and re-emitted at longer wavelengths. We show… read more here.

DOI: 10.1093/mnras/stad1204
Abstract: Recently, the characterisation of binary systems of neutron stars has become central in various fields such as gravitational waves, gamma-ray bursts (GRBs), and the chemical evolution of galaxies. In this work, we explore possible observational… read more here.

DOI: 10.1093/mnras/stx3108
Abstract: Assuming all binary Neutron Star mergers produce Short Gamma Ray Bursts (SGRBs), we combine the merger rates of binary Neutron Stars (BNS) from population synthesis studies, the sensitivities of advanced Gravitational Wave (GW) interferometer networks,… read more here.

DOI: 10.1093/mnras/sty3383
Abstract: Neutron star mergers (NSM) are likely to be the main production sites for the rapid (r-) neutron capture process elements. We study the r-process enrichment of the stellar halo of the Milky Way through NSM,… read more here.

Abstract: We systematically perform numerical-relativity simulations for equal-mass binary neutron star mergers for the models varying the thermal index $\Gamma_{\rm th}$ with three different equations of state (EOSs) of the neutron stars (NSs), which are consistent… read more here.

DOI: 10.1103/physrevc.111.035809
Abstract: Isospin-equilibrating weak processes, called ``Urca"processes, are of fundamental importance in astrophysical environments like (proto-)neutron stars, neutron star mergers, and supernovae. In these environments, matter can reach high temperatures of tens of MeVs and be subject… read more here.

DOI: 10.3389/fspas.2024.1384488
Abstract: Neutron star mergers are astrophysical “gold mines,” synthesizing over half of the elements heavier than iron through rapid neutron capture nucleosynthesis. The observation of the binary neutron star merger GW170817, detected both in gravitational waves… read more here.

DOI: 10.5506/aphyspolb.48.651
Abstract: Neutron-star mergers are closely related to nuclear physics. The nuclear equation of state determines the properties of neutron-star matter and sensitively affects the dynamics of the merger. Consequently, the gravitational-wave signal carries a strong imprint… read more here.
