We present new, exact, rotating and accelerating solutions within the framework of five-dimensional Einstein-Gauss-Bonnet theory at the Chern-Simons point. The rotating solutions describe black holes characterized by a single rotation parameter, a mass parameter, and two extra integration constants that can be interpreted as hairs of a gravitational nature. It is noteworthy that the rotation cannot be removed by a large diffeomorphism. We also extend our procedure to dimension seven, providing a new rotating solution with two rotation parameters pertaining to cubic Lovelock theory with a unique vacuum.

Rotating and accelerating AdS black holes in Einstein-Gauss-Bonnet gravity

In this article we study a family of four-dimensional,   <math> <mi>N</mi> </math>  $$ \mathcal{N} $$  = 2 supergravity theories that interpolates between all the single dilaton truncations of the SO(8) gauged   <math> <mi>N</mi> </math>  $$ \mathcal{N} $$  = 8 supergravity. In this infinitely many theories characterized by two real numbers — the interpolation parameter and the dyonic “angle” of the gauging — we construct non-extremal electrically or magnetically charged black hole solutions and their supersymmetric limits. All the supersymmetric black holes have non-singular horizons with spherical, hyperbolic or planar topology. Some of these supersymmetric and non-extremal black holes are new examples in the   <math> <mi>N</mi> </math>  $$ \mathcal{N} $$  = 8 theory that do not belong to the STU model. We compute the asymptotic charges, thermodynamics and boundary conditions of these black holes and show that all of them, except one, introduce a triple trace deformation in the dual theory.

New non-extremal and BPS hairy black holes in gauged   <math> <mi>N</mi> </math>  $$ \mathcal{N} $$  = 2 and   <math> <mi>N</mi> </math>  $$ \mathcal{N} $$  = 8 supergravity

We investigate the phase diagram of a general class of 4-dimensional exact regular hairy planar black holes. For some particular values of the parameters in the moduli potential, these solutions can be embedded in ω-deformed   <math> <mi>N</mi> </math>  $$ \mathcal{N} $$  = 8 gauged supergravity. We construct the hairy soliton that is the ground state of the theory and show that there exist first order phase transitions.
