Black holes, stationary clouds and magnetic fields

no code implementations9 Feb 2021 Nuno M. Santos, Carlos A. R. Herdeiro

As the electron in the hydrogen atom, a bosonic field can bind itself to a black hole occupying a discrete infinite set of states.

Spin-induced scalarized black holes

no code implementations8 Sep 2020 Carlos A. R. Herdeiro, Eugen Radu, Hector O. Silva, Thomas P. Sotiriou, Nicolás Yunes

It was recently shown that a scalar field suitably coupled to the Gauss-Bonnet invariant $\mathcal{G}$ can undergo a spin-induced linear tachyonic instability near a Kerr black hole.

Quasinormal modes of hot, cold and bald Einstein-Maxwell-scalar black holes

no code implementations26 Aug 2020 Jose Luis Blázquez-Salcedo, Carlos A. R. Herdeiro, Sarah Kahlen, Jutta Kunz, Alexandre M. Pombo, Eugen Radu

Besides the bald Reissner-Nordstr\"om solutions, this coupling allows for two branches of scalarized black holes, termed cold and hot, respectively.

A Double Myers-Perry Black Hole in Five Dimensions

no code implementations8 May 2008 Carlos A. R. Herdeiro, Carmen Rebelo, Miguel Zilhao, Miguel S. Costa

Using the inverse scattering method we construct a six-parameter family of exact, stationary, asymptotically flat solutions of the 4+1 dimensional vacuum Einstein equations, with U(1)^2 rotational symmetry.
