Einstein–Bumblebee-dilaton black hole solution
European Physical Journal C: Particles and Fields, 2023 We obtain new black hole solutions in a Einstein–Bumblebee-scalar theory. By starting with a Einstein–Bumblebee theory in ( $$D+d$$ D + d ) dimensions, the scalar dilaton field and its interaction with the gravitational and Bumblebee fields are obtained ...

Cosmological multi-black-hole solutions [PDF]
Physical Review D, 1993 We present simple, analytic solutions to the Einstein-Maxwell equation, which describe an arbitrary number of charged black holes in a spacetime with positive cosmological constant $ $. In the limit $ =0$, these solutions reduce to the well known Majumdar-Papapetrou (MP) solutions.

Exact charged black hole solutions in D-dimensions in f(R) gravity
European Physical Journal C: Particles and Fields, 2021 We consider Maxwell-f(R) gravity and obtain an exact charged black hole solution with dynamic curvature in D-dimensions. Considering a spherically symmetric metric ansatz and without specifying the form of f(R) we find a general black hole solution in D ...

Analytical Solution and Quasi-Periodic Behavior of a Charged Dilaton Black Hole
Universe, 2021 With the vast breakthrough brought by the Event Horizon Telescope, the theoretical analysis of various black holes has become more critical than ever. In this paper, the second-order asymptotic analytical solution of the charged dilaton black hole flow ...

Critical Solutions of Scalarized Black Holes [PDF]
Symmetry, 2020 We consider charged black holes with scalar hair obtained in a class of Einstein–Maxwell– scalar models, where the scalar field is coupled to the Maxwell invariant with a quartic coupling function. Besides the Reissner–Nordström black holes, these models allow for black holes with scalar hair.

Asymptotically flat vacuum solution for a rotating black hole in a modified gravity theory
European Physical Journal C: Particles and Fields, 2022 The theory of f(R)-gravity is one of the theories of modified Einstein gravity. The vacuum solution, on the other hand, of the field equation is the solution for black hole geometry.

Rotating regular black hole solution [PDF]
Physical Review D, 2014 Based on the Newman-Janis algorithm the Ayon-Beato-Garcia spacetime metric of the regular spherically symmetric, static and charged black hole has been converted into rotational form. It is shown that the derived solution for rotating regular black hole is regular and the critical value of the electric charge $Q$ for which two horizons merge into one ...

Thermal analysis with emission energy of perturbed black hole in f(Q) gravity
Nuclear Physics B, 2023 In the present paper, we investigate the thermodynamics of a new perturbed black hole solution in symmetric teleparallel gravity. Our main focus is on the solution for a nonlinear model like Q+αQ2. We study new features of null geodesics and quasi-normal

Black hole solutions in Rastall theory [PDF]
Canadian Journal of Physics, 2017 The Reissner–Nordström black hole solution in a generic cosmological constant background in the context of Rastall gravity is obtained. It is shown that the cosmological constant arises naturally from the consistency of the non-vacuum field equations of the Rastall theory for a spherical symmetric space–time, rather than its ad hoc introduction in the
