The production of about half of the heavy elements found in nature is assigned to a specific
astrophysical nucleosynthesis process: the rapid neutron-capture process (r process) …

Abstract The Einstein Telescope (ET), the European project for a third-generation
gravitational-wave detector, has a reference configuration based on a triangular shape …

The merger of two neutron stars launches a relativistic jet, which must be driven by a strong
large-scale magnetic field. However, the magnetohydrodynamical mechanism required to …

Observations of neutron-star mergers with distinct messengers, including gravitational
waves and electromagnetic signals, can be used to study the behavior of matter denser than …

The recent detections of the∼ 10 s long γ-ray bursts (GRBs) 211211A and 230307A
followed by softer temporally extended emission (EE) and kilonovae point to a new GRB …

We explore in a parameterized manner a very large range of physically plausible equations
of state (EOSs) for compact stars for matter that is either purely hadronic or that exhibits a …

We present a systematic numerical relativity study of the mass ejection and the associated
electromagnetic transients and nucleosynthesis from binary neutron star (NS) mergers. We …

Gravitational waves detected from the binary neutron star (NS) merger GW170817
constrained the NS equation of state by placing an upper bound on certain parameters …

We revisit the constraint on the maximum mass of cold spherical neutron stars coming from
the observational results of GW170817. We develop a new framework for the analysis by …
