Holographic thermalization, quasinormal modes and superradiance in Kerr-AdS
Vitor Cardoso, Oscar J. C. Dias, Gavin S. Hartnett +2
Black holes in anti-de Sitter (AdS) backgrounds play a pivotal role in the gauge/gravity duality where they determine, among other things, the approach to equilibrium of the dual f…
Collisions of oppositely charged black holes
Miguel Zilhão, Vitor Cardoso, Carlos Herdeiro +2
The first fully non-linear numerical simulations of colliding charged black holes in D=4 Einstein-Maxwell theory were recently reported arXiv:1205.1063. These collisions were perfo…
Collapse of self-interacting fields in asymptotically flat spacetimes: do self-interactions render Minkowski spacetime unstable?
Hirotada Okawa, Vitor Cardoso, Paolo Pani
The nonlinear instability of anti-de Sitter spacetime has recently been established with the striking result that generic initial data collapses to form black holes. This outcome s…
Holographic collisions in confining theories
Vitor Cardoso, Roberto Emparan, David Mateos +2
We study the gravitational dual of a high-energy collision in a confining gauge theory. We consider a linearized approach in which two point particles traveling in an AdS-soliton b…
Black holes with massive graviton hair
Richard Brito, Vitor Cardoso, Paolo Pani
No-hair theorems exclude the existence of nontrivial scalar and massive vector hair outside four-dimensional, static, asymptotically flat black-hole spacetimes. We show, by explici…
Black hole bombs and explosions: from astrophysics to particle physics
Vitor Cardoso
Black holes are the elementary particles of gravity, the final state of sufficiently massive stars and of energetic collisions. With a forty-year long history, black hole physics i…
Black holes with surrounding matter in scalar-tensor theories
Vitor Cardoso, Isabella P. Carucci, Paolo Pani +1
We uncover two mechanisms that can render Kerr black holes unstable in scalar-tensor gravity, both associated to the presence of matter in the vicinity of the black hole and the fa…
Astrophysical signatures of boson stars: quasinormal modes and inspiral resonances
Caio F. B. Macedo, Paolo Pani, Vitor Cardoso +1
Compact bosonic field configurations, or boson stars, are promising dark matter candidates which have been invoked as an alternative description for the supermassive compact object…
Partially massless gravitons do not destroy general relativity black holes
Richard Brito, Vitor Cardoso, Paolo Pani
Recent nonlinear completions of Fierz-Pauli theory for a massive spin-2 field include nonlinear massive gravity and bimetric theories. The spectrum of black-hole solutions in these…
Quasinormal ringing of Kerr black holes. II. Excitation by particles falling radially with arbitrary energy
Zhongyang Zhang, Emanuele Berti, Vitor Cardoso
The analytical understanding of quasinormal mode ringing requires an accurate knowledge of the Green's function describing the response of the black hole to external perturbations.…
Matter around Kerr black holes in scalar-tensor theories: scalarization and superradiant instability
Vitor Cardoso, Isabella P. Carucci, Paolo Pani +1
In electrovacuum stationary, asymptotically flat black holes in scalar-tensor theories of gravity are described by the Kerr-Newman family of solutions, just as in general relativit…
Massive spin-2 fields on black hole spacetimes: Instability of the Schwarzschild and Kerr solutions and bounds on the graviton mass
Richard Brito, Vitor Cardoso, Paolo Pani
Massive bosonic fields of arbitrary spin are predicted by general extensions of the Standard Model. It has been recently shown that there exists a family of bimetric theories of gr…
Numerical simulations of single and binary black holes in scalar-tensor theories: circumventing the no-hair theorem
Emanuele Berti, Vitor Cardoso, Leonardo Gualtieri +2
Scalar-tensor theories are a compelling alternative to general relativity and one of the most accepted extensions of Einstein's theory. Black holes in these theories have no hair,…
Equation-of-state-independent relations in neutron stars
Andrea Maselli, Vitor Cardoso, Valeria Ferrari +2
Neutron stars are extremely relativistic objects which abound in our universe and yet are poorly understood, due to the high uncertainty on how matter behaves in the extreme condit…
Into the lair: gravitational-wave signatures of dark matter
Caio F. B. Macedo, Paolo Pani, Vitor Cardoso +1
The nature and properties of dark matter (DM) are both outstanding issues in physics. Besides clustering in halos, the universal character of gravity implies that self-gravitating…
