Black holes with a null Killing vector in new massive gravity in three dimensions
نویسنده
چکیده
We investigate solutions of new massive gravity with two commuting Killing vectors, one of which is null, with a special emphasis on black hole solutions. Besides extreme BTZ black holes and, for a special value of the coupling constant, massless null warped black holes, we also obtain for a critical coupling a family of massive “log” black holes. These are asymptotic to the extreme BTZ black holes in the sense of log gravity. ∗Email: [email protected]

Black holes with a null Killing vector in three-dimensional massive gravity
We investigate solutions of new massive gravity with two commuting Killing vectors, one of which is null, with a special emphasis on black hole solutions. Besides extreme BTZ black holes and, for a special value of the coupling constant, massless null warped black holes, we also obtain for a critical coupling a family of massive “log” black holes. These are asymptotic to the extreme BTZ black h...
متن کاملSpherically Symmetric Solutions in a New Braneworld Massive Gravity Theory
In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...
متن کاملHigher dimensional Chern-Simons theories and topological black holes
It has been recently pointed out that black holes of constant curvature with a “chronological singularity” can be constructed in any spacetime dimension. These black holes share many common properties with the 2+1 black hole. In this contribution we give a brief summary of these new black holes and consider them as solutions of a Chern-Simons gravity theory. We also provide a brief introduction...
متن کاملStatic and rotating electrically charged black holes in three-dimensional Brans-Dicke gravity theories
We obtain static and rotating electrically charged black holes of a Einstein-Maxwell-Dilaton theory of the Brans-Dicke type in (2+1)dimensions. The theory is specified by three fields, the dilaton φ, the graviton gμν and the electromagnetic field Fμν , and two parameters, the cosmological constant Λ and the Brans-Dicke parameter ω. It contains eight different cases, of which one distinguishes a...
متن کاملConservation Laws and 2d Black Holes in Dilaton Gravity
A very general class of Lagrangians which couple scalar fields to gravita-tion and matter in two spacetime dimensions is investigated. It is shown that a vector field exists along whose flow lines the stress-energy tensor is conserved , regardless of whether or not the equations of motion are satisfied or if any Killing vectors exist. Conditions necessary for the existence of Killing vectors ar...
