The Gravitational Wave Memory from Binary Neutron Star Mergers
Jamie Bamber, Antonios Tsokaros, Milton Ruiz +4
The gravitational wave signal produced by the merger of two compact objects includes both an oscillatory transient and a non-oscillatory part, the so-called memory effect. This pro…
Impact of Magnetic Field Topology on Electromagnetic and Gravitational Waves from Binary Neutron Star Merger Remnants
Inês Rainho, Jamie Bamber, Davide Guerra +4
We perform general relativistic magnetohydrodynamic (GRMHD) simulations of binary neutron star (BNS) mergers with four distinct magnetic field topologies: (i) a dipole pulsar-like…
Evolution of a black hole cluster in full general relativity
Jamie Bamber, Stuart L. Shapiro, Milton Ruiz +1
We evolve for the first time in full general relativity a small, collisional N-body black hole cluster of arbitrary total mass M. The bound cluster is initially compact (radius R/M…
Postmerger multimessenger analysis of binary neutron stars: Effect of the magnetic field strength and topology
Jamie Bamber, Antonios Tsokaros, Milton Ruiz +1
The oscillation modes of neutron star (NS) merger remnants, as encoded by the kHz postmerger gravitational wave (GW) signal, hold great potential for constraining the as-yet undete…
Masking equation of state effects in binary neutron star mergers
Antonios Tsokaros, Jamie Bamber, Milton Ruiz +1
Recent nonmagnetized studies of binary neutron star mergers have indicated the possibility of identifying equation of state features, such as a phase transition or a quark-hadron c…
