Neutrino masses and mixings produce vacuum oscillations, an established quantum
mechanical phenomenon. In matter, the Mikheev-Smirnov-Wolfenstein effect, due to …

Gravitational-wave detectors have transformed the way we observe the Universe. Together
with ground and space electromagnetic observatories, they have provided key insights into …

In recent years our understanding of the dense matter equation of state (EOS) of neutron
stars has significantly improved by analyzing multimessenger data from radio/X-ray pulsars …

Abstract The Ultraviolet Transient Astronomy Satellite (ULTRASAT) is scheduled to be
launched to geostationary orbit in 2027. It will carry a telescope with an unprecedentedly …

We present a new moment-based energy-integrated neutrino transport code for neutron star
merger simulations in general relativity. In the merger context, ours is the first code to include …

We perform a general-relativistic neutrino-radiation magnetohydrodynamic simulation of a
one second-long binary neutron star merger on the Japanese supercomputer Fugaku using …

The metastable hypermassive neutron star produced in the coalescence of two neutron stars
can copiously produce axions that radiatively decay into O (100) MeV photons. These …

We present an improved version of the 3D Monte Carlo radiative transfer code possis to
model kilonovae from neutron star mergers, wherein nuclear heating rates, thermalization …

A compact accretion disk may be formed in the merger of two neutron stars or of a neutron
star and a stellar-mass black hole. Outflows from such accretion disks have been identified …

We investigate the quark deconfinement phase transition in the context of binary neutron
star (BNS) mergers. We treat hadronic matter using a Brueckner-Hartree-Fock quantum …
