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…
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…
An effective model for magnetic field amplification by the magnetorotational and parasitic instabilities
Miquel Miravet-Tenés, Martin E. Pessah
The magnetorotational instability (MRI) is considered a leading mechanism for driving angular momentum transport in differentially rotating astrophysical flows, including accretion…
Gravitational Wave Memory Imprints on the CMB from Populations of Massive Black Hole Mergers
Lorenz Zwick, David O'Neill, Kai Hendriks +2
Aims: To showcase and characterise the rich phenomenology of temperature fluctuation patterns that are imprinted on the CMB by the gravitational wave memory (GWM) of massive black…
