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…
Bohmian Quantum Cosmology from the Wheeler-DeWitt Equation
Spyros Basilakos, Gerasimos Kouniatalis, Emmanuel N. Saridakis +1
We construct a Bohmian quantum cosmological model for a spatially flat Friedmann Robertson Walker universe filled with a single scalar field whose potential provides a unified desc…
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…
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…
Equivalence of cosmology with quintom-like scenario: the phantom field as effective realization of the non-trivial connection
Spyros Basilakos, Andronikos Paliathanasis, Emmanuel N. Saridakis
We show that cosmology with a non-trivial connection, namely the Connection II of the literature, is dynamically equivalent with a quintom-like model. In particular, we show…
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…
