Nonradial perturbations of static charged wormholes
Jose Luis Blázquez-Salcedo, Luis Manuel González-Romero, Fech Scen Khoo +2
We investigate the nonradial quasinormal-mode spectrum of static charged Ellis--Bronnikov wormholes in Einstein--Maxwell theory minimally coupled to a phantom scalar field. The bac…
Hierarchy of Angular Instabilities in Scalarized Black Holes
Jose Luis Blázquez-Salcedo, Luis Manuel González-Romero, Fech Scen Khoo +2
We investigate the stability of scalarized black holes in Einstein-scalar-Gauss-Bonnet-Ricci theory along their fundamental branches. We show that initially stable solutions first…
Radial perturbations of charged wormholes
Jose Luis Blázquez-Salcedo, Luis Manuel González-Romero, Fech Scen Khoo +2
Ellis-Bronnikov wormholes suffer from an unstable radial mode. Here we investigate the evolution of the unstable mode(s) for charged wormholes. We show that the instability remains…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Testing gravity with the latent heat of neutron star matter
Pablo Navarro Moreno, Aneta Wojnar, Felipe J. Llanes-Estrada
The Seidov limit is a bound on the maximum latent heat that a presumed first-order phase transition of neutron-star matter can have before its excess energy density, not compensate…
