“…They exist at the threshold of the superradiant instabilities triggered by that test field. Recently, a considerable number of studies of such clouds has appeared in the literature, mostly in asymptotically flat spacetimes [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26], but also in asymptotically AdS spacetimes [5,7]. 2 Most of these studies have addressed scalar field clouds 3 (even though marginal clouds [30] have been considered for a Proca field [31] in a charged BH background).…”

Scalar and gravitational perturbations on Kerr-anti-de Sitter (Kerr-AdS) black holes have been addressed in the literature and have been shown to exhibit a rich phenomenology. In this paper, we complete the analysis of bosonic fields on this background by studying Maxwell perturbations, focusing on superradiant instabilities and vector clouds. For this purpose, we solve the Teukolsky equations numerically, imposing the boundary conditions we have proposed in [1] for the radial Teukolsky equation. As found therein, two Robin boundary conditions can be imposed for Maxwell fields on Kerr-AdS black holes, one of which produces a new set of quasinormal modes even for Schwarzschild-AdS black holes. Here, we show these different boundary conditions produce two different sets of superradiant modes. Interestingly, the "new modes" may be unstable in a larger parameter space. We then study stationary Maxwell clouds that exist at the threshold of the superradiant instability, with the two Robin boundary conditions. These clouds, obtained at the linear level, indicate the existence of a new family of black hole solutions at the nonlinear level, within the Einstein-Maxwell-AdS system, branching off from the KerrNewman-AdS family. As a comparison with the Maxwell clouds, scalar clouds on Kerr-AdS black holes are also studied, and it is shown there are Kerr-AdS black holes that are stable against scalar, but not vector, modes with the same "quantum numbers".

“…In the same direction, it would also be interesting to find solutions where these fields act like a Kerr black hole hair or clouds following the steps of [27][28][29][30][31]33]. On the other hand, clouds may also exist surrounding static black holes [32].…”

In this paper, we study gauged solutions associated to a massive vector field representing a spin-one condensate, namely the Proca field. We focus on regular spherically-symmetric solutions which we construct either using a self-interaction potential or general relativity in order to glue the solutions together. We start generating non-gravitating solutions, so-called, Proca Q-balls and charged Proca Q-balls. Then, we turn-on backreaction on the metric, allowing gravity to hold together the Proca condensate, to study the so-called Proca stars, charged Proca stars, Proca Q-stars and charged Proca Q-stars.

“…A test field analysis shows the existence of stationary, everywhere regular (on and outside the horizon) solutions of the scalar 209,[282][283][284] or Proca field 277 on the Kerr BH spacetime: stationary scalar or Proca clouds around Kerr BHs. The existence of these stationary clouds is intimately related to superradiance, as we now illustrate for the scalar case.…”

We review recent progress in the application of numerical relativity techniques to astrophysics and high-energy physics. We focus on recent developments regarding the spin evolution in black hole binaries, high-energy black hole collisions, compact object solutions in scalar-tensor gravity, superradiant instabilities, hairy black hole solutions in Einstein's gravity coupled to fundamental fields, and the possibility to gain insight into these phenomena using analog gravity models.
