The mergers of binaries containing neutron stars and stellar-mass black holes are the most promising sources for direct detection in gravitational waves by the interferometers Advanced LIGO and Virgo over the next few years. The concurrent detection of electromagnetic emission from these events would greatly enhance the scientific return of these discoveries. Here we review the state of the art in modeling the electromagnetic signal of neutron star binary mergers across different phases of the…

Neutron Star Mergers and Nucleosynthesis of Heavy Elements
The existence of neutron star mergers has been supported since the discovery of the binary pulsar and the observation of its orbital energy loss, consistent with General Relativity. They are
The Physics of Kilonovae
The science returns of gravitational wave astronomy will be maximized if electromagnetic counterparts to gravitational-wave sources can be identified. Kilonovae are promising counterparts to compact
Pre-merger Electromagnetic Counterparts of Binary Compact Stars
We investigate emission signatures of binary compact star gravitational wave (GW) sources consisting of strongly magnetized neutron stars (NSs) and/or white dwarfs (WDs) in their late-time inspiral

On August 17, 2017, less than two years after the direct detection of gravitational radiation from the merger of two ∼ 30 M ⊙ black holes, a binary neutron star merger was identified as the source of
Estimates of the Early Electromagnetic Emission from Compact Binary Mergers
Compact binary mergers that involve at least one neutron star, either binary neutron star or black hole–neutron star coalescences, are thought to be the potential sources of electromagnetic emission

The astrophysical origin of the rapid neutron capture elements has been a puzzle since the 1950s. While evidence for a compact binary merger origin has been growing over the last two decades, the
Radio Counterparts of Compact Binary Mergers Detectable in Gravitational Waves: A Simulation for an Optimized Survey
Mergers of binary neutron stars and black hole–neutron star binaries produce gravitational-wave (GW) emission and outflows with significant kinetic energies. These outflows result in radio emissions
Analytic properties of the electromagnetic field of binary compact stars and electromagnetic precursors to gravitational waves
We analytically study the properties of the electromagnetic field in vacuum around close binary compact stars containing at least one neutron star. We show that the orbital motion of the neutron star
ν bhlight : Radiation GRMHD for Neutrino-driven Accretion Flows
The 2017 detection of the in-spiral and merger of two neutron stars was a landmark discovery in astrophysics. We now know that such mergers are central engines of short gamma ray bursts and sites of


Measuring neutron-star properties via gravitational waves from neutron-star mergers.
We demonstrate by a large set of merger simulations for symmetric binary neutron stars (NSs) that there is a tight correlation between the frequency peak of the postmerger gravitational-wave (GW)
Electromagnetic and gravitational outputs from binary-neutron-star coalescence.
Simulation results suggest that some binary neutron-star mergers are ideal candidates for multimessenger astronomy, and that this power can outshine pulsars in binaries.
Transient Events from Neutron Star Mergers
Mergers of neutron stars (NS + NS) or neutron stars and stellar-mass black holes (NS + BH) eject a small fraction of matter with a subrelativistic velocity. Upon rapid decompression, nuclear-density
Gravitational waves and neutrino emission from the merger of binary neutron stars.
The neutrino luminosity curve when a black hole is formed for the first time is presented and the effective amplitude of gravitational waves from the HMNS is 4-6×10(-22) at f=2.1-2.5  kHz.
Electromagnetic counterparts of compact object mergers powered by the radioactive decay of r‐process nuclei
The most promising astrophysical sources of kHz gravitational waves (GWs) are the inspiral and merger of binary neutron star(NS)/black hole systems. Maximizing the scientific return of a GW detection
Mergers of binary neutron stars (NSs) are among the most promising gravitational wave (GW) sources. Next generation GW detectors are expected to detect signals from NS mergers within about 200 Mpc.
The coalescence of black-hole-neutron-star binaries is expected to be a principal source of gravitational waves for the next generation of detectors, Advanced LIGO and Advanced Virgo. For black hole
Eccentric black-hole-neutron-star mergers

Recent observations indicate that in a large fraction of binary neutron star (BNS) mergers a long-lived neutron star (NS) may be formed rather than a black hole. Unambiguous electromagnetic (EM)
Formation of very strongly magnetized neutron stars - Implications for gamma-ray bursts
It is proposed that the main observational signature of magnetars, high-field neutron stars, is gamma-ray bursts powered by their vast reservoirs of magnetic energy. If they acquire large recoils,
