Charged Fermions and Strong Cosmic Censorship
Kyriakos Destounis
It was recently shown that the Strong Cosmic Censorship conjecture might be violated for near-extremally-charged black holes in de Sitter space. Here, we extend our study to charge…
Strong cosmic censorship in charged black-hole spacetimes: still subtle
Vitor Cardoso, Joao L. Costa, Kyriakos Destounis +2
It was recently shown that Strong Cosmic Censorship may be violated in highly charged black-hole spacetimes living in a universe with a positive cosmological constant. Several foll…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
Stability under scalar perturbations and quasinormal modes of 4D Einstein-Born-Infeld dilaton spacetime: Exact spectrum
Kyriakos Destounis, Grigoris Panotopoulos, Ángel Rincon
We study the stability under scalar perturbations, and we compute the quasinormal modes of the Einstein-Born-Infeld dilaton spacetime in 1+3 dimensions. Solving the full radial equ…
