Electromagnetic duality degeneracy in dynamical black hole mergers
José Ferreira, Gabriele Bozzola, Carlos A. R. Herdeiro +2
Electromagnetic duality is a symmetry of the source-free Einstein-Maxwell equations that rotates electric and magnetic fields while leaving the stress-energy tensor invariant. We p…
Ringdown mode amplitudes of charged binary black holes
Zexin Hu, Daniela D. Doneva, Ziming Wang +4
The ringdown phase of the binary black hole (BBH) merger provides a clean and direct probe of strong-field gravity and tests of the nature of black holes. The quasinormal mode (QNM…
Effects of eccentricity on accreting binary black holes: MHD simulations in full GR reveal novel periodicities in jet power and synchrotron spectra
Vikram Manikantan, Vasileios Paschalidis, Gabriele Bozzola
We perform simulations of magnetohydrodynamic accretion onto equal-mass, nonspinning binary black holes in 3+1 full general relativity addressing the effects of orbital eccentricit…
High-energy interactions of charged black holes in full general relativity II: Near-extremal merger remnants and universality with the irreducible mass
M A. M. Smith, Vasileios Paschalidis, Gabriele Bozzola
In a previous paper, arXiv:2411.11960 [gr-qc], we initiated a study of high-energy interactions of charged binary black holes near the scattering threshold, focusing on zoom-whirl…

Exploring pathways to forming twin stars
Mahdi Naseri, Gabriele Bozzola, Vasileios Paschalidis
A viable model for the dense matter equation of state above the nuclear saturation density includes a hadron-to-quark phase transition at densities relevant to compact objects. In…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
Not all spacetime coordinates for general-relativistic ray tracing are created equal
Gabriele Bozzola, Chi-kwan Chan, Vasileios Paschalidis
Models for the observational appearance of astrophysical black holes rely critically on accurate general-relativistic ray tracing and radiation transport to compute the intensity m…
Can quasi-circular mergers of charged black holes produce extremal black holes?
Gabriele Bozzola, Vasileios Paschalidis
In contrast to energy and angular momentum, electric charge is conserved in mergers of charged black holes. This opens up the possibility for the remnant to have Kerr-Newman parame…
