The increase in the sensitivity of gravitational wave (GW) interferometers will bring additional detections of binary black hole (BBH) and double neutron star (NS) mergers. It will also very likely add many merger events of BH–NS binaries. Distinguishing mixed binaries from BBHs mergers for high mass ratios could be challenging because in this situation the NS coalesces with the BH without experiencing significant disruption. To investigate the transition of mixed binary mergers into those… Expand


Fully General Relativistic Simulations of Black Hole-Neutron Star Mergers
Black hole-neutron star (BHNS) binaries are expected to be among the leading sources of gravitational waves observable by ground-based detectors, and may be the progenitors of short-hard gamma-rayExpand
General relativistic simulations of black-hole-neutron-star mergers: Effects of black-hole spin
Black-hole-neutron-star (BHNS) binary mergers are candidate engines for generating both short-hard gamma-ray bursts and detectable gravitational waves. Using our most recent conformal thin-sandwichExpand
Massive disc formation in the tidal disruption of a neutron star by a nearly extremal black hole
Black hole–neutron star (BHNS) binaries are important sources of gravitational waves for second-generation interferometers, and BHNS mergers are also a proposed engine for short, hard gamma-rayExpand
Jet launching from binary black hole-neutron star mergers: Dependence on black hole spin, binary mass ratio, and magnetic field orientation
Black hole-neutron star (BHNS) mergers are one of the most promising targets for multimessenger astronomy. Using general relativistic magnetohydrodynamic simulations of BHNS undergoing merger weExpand
Dynamical ejecta from precessing neutron star-black hole mergers with a hot, nuclear-theory based equation of state
Neutron star-black hole binaries are among the strongest sources of gravitational waves detectable by current observatories. They can also power bright electromagnetic signals (gamma-ray bursts,Expand
Black hole-neutron star mergers: Effects of the orientation of the black hole spin
The spin of black holes in black hole-neutron star binaries can have a strong influence on the merger dynamics and the post-merger state; a wide variety of spin magnitudes and orientations areExpand
Gravitational waves from nonspinning black hole-neutron star binaries: dependence on equations of state
We report results of a numerical-relativity simulation for the merger of a black hole-neutron star binary with a variety of equations of state (EOSs) modeled by piecewise polytropes. We focus, inExpand
Black hole-neutron star mergers for 10 M_☉ black holes
General relativistic simulations of black hole-neutron star mergers have currently been limited to low-mass black holes (less than 7 solar mass), even though population synthesis models indicate thatExpand
Numerical simulations of neutron star-black hole binaries in the near-equal-mass regime
Simulations of neutron star-black hole (NSBH) binaries generally consider black holes with masses in the range $(5-10)M_\odot$, where we expect to find most stellar mass black holes. The existence ofExpand
Ultra-Close Encounters of Stars With Massive Black Holes: Tidal Disruption Events With Prompt Hyperaccretion
A bright flare from a galactic nucleus followed at late times by a $t^{-5/3}$ decay in luminosity is often considered the signature of the complete tidal disruption of a star by a massive black hole.Expand
