Endorsing black holes with beyond Horndeski primary hair: An exact solution framework for scalarizing in every dimension
Olaf Baake, Adolfo Cisterna, Mokhtar Hassaine +1
This work outlines a straightforward mechanism for endorsing primary hair into Schwarzschild black holes, resulting in a unique modification within the framework of a special scala…
Quantum backreaction for overspinning BTZ geometries
Olaf Baake, Jorge Zanelli
We examine the semiclassical backreaction of a conformally coupled scalar field on an overspinning BTZ geometry. This extends the work done on a similar problem for ()- AdS ge…
Rotating stealth black holes with a cohomogeneity-1 metric
Olaf Baake, Mokhtar Hassaine
In five dimensions we consider a general shift symmetric and parity preserving scalar tensor action that contains up to second order covariant derivatives of the scalar field. A ro…
Regular black holes and gravitational particle-like solutions in generic DHOST theories
Olaf Baake, Christos Charmousis, Mokhtar Hassaine +1
We construct regular, asymptotically flat black holes of higher order scalar tensor (DHOST) theories, which are obtained by making use of a generalized Kerr-Schild solution generat…
Spinning black holes for generalized scalar tensor theories in three dimensions
Olaf Baake, Moises Bravo-Gaete, Mokhtar Hassaine
We consider a general class of scalar tensor theories in three dimensions whose action contains up to second-order derivatives of the scalar field with coupling functions that only…
Superradiance of a charged scalar field coupled to the Einstein-Maxwell equations
Olaf Baake, Oliver Rinne
We consider the Einstein-Maxwell-Klein-Gordon equations for a spherically symmetric scalar field scattering off a Reissner-Nordström black hole in asymptotically flat spacetime. Th…
