Addendum to "Strong cosmic censorship: The nonlinear story"
Raimon Luna, Miguel Zilhão, Vitor Cardoso +2
We clarify a number of issues that arise when extending the analysis of Strong Cosmic Censorship (SCC) to perturbations of highly charged Reissner-Nordström de Sitter (RNdS) spacet…
On the dynamical bar-mode instability in spinning bosonic stars
Fabrizio Di Giovanni, Nicolas Sanchis-Gual, Pablo Cerdá-Durán +4
Spinning bosonic stars (SBSs) can form from the gravitational collapse of a dilute cloud of scalar/Proca particles with non-zero angular momentum. In a recent work we found that th…
Black hole binaries and light fields: Gravitational molecules
Taishi Ikeda, Laura Bernard, Vitor Cardoso +1
We show that light scalars can form quasibound states around binaries. In the nonrelativistic regime, these states are formally described by the quantum-mechanical Schrodinger equa…
Synchronised gravitational atoms from mergers of bosonic stars
Nicolas Sanchis-Gual, Miguel Zilhão, Carlos Herdeiro +3
If ultralight bosonic fields exist in Nature as dark matter, superradiance spins down rotating black holes (BHs), dynamically endowing them with equilibrium bosonic clouds, here du…
Crossing a large- phase transition at finite volume
Yago Bea, Oscar J. C. Dias, Thanasis Giannakopoulos +4
The existence of phase-separated states is an essential feature of infinite-volume systems with a thermal, first-order phase transition. At energies between those at which the phas…
Hyperbolicity of General Relativity in Bondi-like gauges
Thanasis Giannakopoulos, David Hilditch, Miguel Zilhao
Bondi-like (single-null) characteristic formulations of general relativity are used for numerical work in both asymptotically flat and anti-de Sitter spacetimes. Well-posedness of…
