Multimessenger Signatures of Tilted, Self-Gravitating, Black Hole Disks
Milton Ruiz, Antonios Tsokaros, Stuart L. Shapiro
We perform fully relativistic GRMHD simulations of magnetized, self-gravitating black hole-disk (BHD) systems in which the black hole spin is misaligned with the disk angular momen…
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…
Binary black holes in magnetized AGN disks
Raj Kishor Joshi, Aryan Bhake, Biswajit Banerjee +7
Stellar-mass binary black hole (BBH) mergers occurring within the disks of active galactic nuclei (AGN) are promising sources for gravitational waves detectable by the LIGO, Virgo,…
Subgrid modelling of MRI-driven turbulence in differentially rotating neutron stars
Miquel Miravet-Tenés, Martin Obergaulinger, Pablo Cerdá-Durán +2
Following a binary neutron star (BNS) merger, the transient remnant is often a fast-spinning, differentially rotating, magnetised hypermassive neutron star (HMNS). This object is p…
Impact of rotation on magnetic field stability and orientation in isolated neutron stars
Fabrizio Venturi Piñas, Anson Ka Long Yip, Patrick Chi-Kit Cheong +1
Neutron stars are the most compact horizonless objects in the Universe, exhibiting the strongest known magnetic fields. They are potential sources of coincident gravitational waves…
