Neutrino Signatures From Young Neutron Stars
Luke F. Roberts, Sanjay Reddy
After a successful core collapse supernova (CCSN) explosion, a hot dense proto-neutron star (PNS) is left as a remnant. Over a time of twenty or so seconds, this PNS emits the majo…
Probing Extreme-Density Matter with Gravitational Wave Observations of Binary Neutron Star Merger Remnants
David Radice, Sebastiano Bernuzzi, Walter Del Pozzo +2
We present a proof-of-concept study, based on numerical-relativity simulations, of how gravitational waves (GWs) from neutron star merger remnants can probe the nature of matter at…
Dynamics, nucleosynthesis, and kilonova signature of black hole - neutron star merger ejecta
Rodrigo Fernández, Francois Foucart, Daniel Kasen +3
We investigate the ejecta from black hole - neutron star mergers by modeling the formation and interaction of mass ejected in a tidal tail and a disk wind. The outflows are neutron…
Charged current neutrino interactions in hot and dense matter
Luke F. Roberts, Sanjay Reddy
We derive the charged current absorption rate of electron and anti-electron neutrinos in dense matter using a fully relativistic approach valid at arbitrary matter degeneracy. We i…
Impact of an improved neutrino energy estimate on outflows in neutron star merger simulations
Francois Foucart, Evan O'Connor, Luke Roberts +3
Binary neutron star mergers are promising sources of gravitational waves for ground-based detectors such as Advanced LIGO. Neutron-rich material ejected by these mergers may also b…
General Relativistic Three-Dimensional Multi-Group Neutrino Radiation-Hydrodynamics Simulations of Core-Collapse Supernovae
Luke F. Roberts, Christian D. Ott, Roland Haas +3
We report on a set of long-term general-relativistic three-dimensional (3D) multi-group (energy-dependent) neutrino-radiation hydrodynamics simulations of core-collapse supernovae.…
