The high-energy collision of two black holes
U. Sperhake, V. Cardoso, F. Pretorius +2
We study the head-on collision of two highly boosted equal mass, nonrotating black holes. We determine the waveforms, radiated energies, and mode excitation in the center of mass f…
Quasinormal modes and thermodynamic phase transitions
Emanuele Berti, Vitor Cardoso
It has recently been suggested that scalar, Dirac and Rarita-Schwinger perturbations are related to thermodynamic phase transitions of charged (Reissner-Nordström) black holes. In…
Multipolar analysis of spinning binaries
E. Berti, V. Cardoso, J. A. Gonzalez +2
We present a preliminary study of the multipolar structure of gravitational radiation from spinning black hole binary mergers. We consider three different spinning binary configura…
Eccentric binary black-hole mergers: The transition from inspiral to plunge in general relativity
U. Sperhake, E. Berti, V. Cardoso +3
We study the transition from inspiral to plunge in general relativity by computing gravitational waveforms of non-spinning, equal-mass black-hole binaries. We consider three sequen…
Ergoregion instability of ultra-compact astrophysical objects
Vitor Cardoso, Paolo Pani, Mariano Cadoni +1
Most of the properties of black holes can be mimicked by horizonless compact objects such as gravastars and boson stars. We show that these ultra-compact objects develop a strong e…
On the gravitational stability of D1-D5-P black holes
Vitor Cardoso, Oscar J. C. Dias, Robert C. Myers
We examine the stability of the nonextremal D1-D5-P black hole solutions. In particular, we look for the appearance of a superradiant instability for the spinning black holes but w…
