Unification of gravity with other interactions, achieving the ultimate framework of quantum
gravity, and fundamental problems in particle physics and cosmology motivate to consider …

We investigate thermodynamics of static and spherically symmetric black holes (BHs) in the
Horndeski theories. Because of the presence of the higher-derivative interactions and the …

A bstract Employing the covariant phase space formalism, we discuss black hole
thermodynamics in four-dimensional scalar-tensor Einstein-Gauss-Bonnet gravity. We argue …

A bstract In the simplest scalar-tensor theories, wherein the scalar field is non-minimally
coupled to the Ricci scalar, spontaneous scalarization of electrovacuum black holes (BHs) …

Shift-symmetric Horndeski theories admit an interesting class of Schwarzschild black hole
solutions exhibiting time-dependent scalar hair. By making use of Lemaître coordinates, we …

Black holes are predictions of Albert Einstein's theory of general relativity and have been the
focus of intense studies for over a century, as they provide a rich source of theoretical and …

The general solutions of Horndeski‐like gravity that can interpolate between the de Sitter
and anti‐de Sitter regimes are presented. In particular, the first‐order formalism with two …

A bstract We consider diffeomorphism invariant theories of gravity with arbitrary higher
derivative terms in the Lagrangian as corrections to the leading two derivative theory of …

We construct spontaneously vectorized black holes where a real vector field is coupled to
the Gauss-Bonnet invariant. We employ three coupling functions for the vector field, and …

Adopting the manifestation of low frequency and low mass for the scalar perturbation, we
perform a semiclassical analysis of the superradiance phenomenon for a rotating hairy …
