Numerical relativity simulations of the neutron star merger GW190425: microphysics and mass ratio effects
A. Camilletti, L. Chiesa, G. Ricigliano +7
GW190425 was the second gravitational wave (GW) signal compatible with a binary neutron star (BNS) merger detected by the Advanced LIGO and Advanced Virgo detectors. Since no elect…
Gravity and Light: Combining Gravitational Wave and Electromagnetic Observations in the 2020s
R. J. Foley, K. D. Alexander, I. Andreoni +110
As of today, we have directly detected exactly one source in both gravitational waves (GWs) and electromagnetic (EM) radiation, the binary neutron star merger GW170817, its associa…
Evidence for X-ray Emission in Excess to the Jet Afterglow Decay 3.5 yrs After the Binary Neutron Star Merger GW 170817: A New Emission Component
A. Hajela, R. Margutti, J. S. Bright +34
For the first years after the binary neutron star merger event GW 170817 the radio and X-ray radiation has been dominated by emission from a structured relativistic off-axi…
Neutrino-driven Turbulent Convection and Standing Accretion Shock Instability in Three-Dimensional Core-Collapse Supernovae
E. Abdikamalov, C. D. Ott, D. Radice +6
We conduct a series of numerical experiments into the nature of three-dimensional (3D) hydrodynamics in the postbounce stalled-shock phase of core-collapse supernovae using 3D gene…
Investigating the Impact of Higher-Order Phase Transitions in Binary Neutron-Star Mergers
P. Hammond, A. Clevinger, M. Albino +10
In this paper we investigate quark deconfinement in neutrons stars and their mergers, focusing on the effects of higher orders for the phase transition between hadronic and quark m…
Probing the incompressibility of nuclear matter at ultra-high density through the prompt collapse of asymmetric neutron star binaries
A. Perego, D. Logoteta, D. Radice +5
Using 250 neutron star merger simulations with microphysics, we explore for the first time the role of nuclear incompressibility in the prompt collapse threshold for binaries with…
Three approaches for the classification of protoneutron star oscillation modes
M. C. Rodriguez, Ignacio F. Ranea-Sandoval, C. Chirenti +1
The future detection of gravitational waves (GWs) from a galactic core-collapse supernova will provide information on the physics inside protoneutron stars (PNS). In this work, we…
Production of very light elements and strontium in the early ejecta of neutron star mergers
A. Perego, D. Vescovi, A. Fiore +10
We study the production of very light elements () in the dynamical and spiral-wave wind ejecta of binary neutron star mergers by combining detailed nucleosynthesis calculat…
Horizons: Nuclear Astrophysics in the 2020s and Beyond
H. Schatz, A. D. Becerril Reyes, A. Best +162
Nuclear Astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the…
Two years of non-thermal emission from the binary neutron star merger GW170817: rapid fading of the jet afterglow and first constraints on the kilonova fastest ejecta
A. Hajela, R. Margutti, K. D. Alexander +27
We present Chandra and VLA observations of GW170817 at ~521-743 days post merger, and a homogeneous analysis of the entire Chandra data set. We find that the late-time non-thermal…
