Covariant Symplectic Structure and Conserved Charges of Topologically Massive Gravity
Caner Nazaroglu, Yavuz Nutku, Bayram Tekin
We present the covariant symplectic structure of the Topologically Massive Gravity and find a compact expression for the conserved charges of generic spacetimes with Killing symmet…
Type D Solutions of 3D New Massive Gravity
Haji Ahmedov, Alikram N. Aliev
In a recent reformulation of three-dimensional new massive gravity (NMG), the field equations of the theory consist of a massive (tensorial) Klein-Gordon type equation with a curva…
More on New Massive Gravity: Exact Solutions
Haji Ahmedov, Alikram N. Aliev
We give a novel description of the recently proposed theory of new massive gravity (NMG) in three dimensions. We show that in terms of a Dirac type differential operator acting on…
Black String and Gödel type Solutions of Chern-Simons Modified Gravity
Haji Ahmedov, Alikram N. Aliev
Chern-Simons (CS) modified gravity with a prescribed CS scalar field does not admit rotating black hole solutions with spherical topology of the horizon. In this paper, we show tha…
Uniqueness of Rotating Charged Black Holes in Five-Dimensional Minimal Gauged Supergravity
Haji Ahmedov, Alikram N. Aliev
We study a five-dimensional spacetime admitting, in the presence of torsion, a non-degenerate conformal Killing-Yano 2-form which is closed with respect to both the usual exterior…
Chern-Simons S-Brane Solutions in M-theory and Accelerating Cosmologies
Nihat Sadik Deger, Ali Kaya
We construct an intersecting S-brane solution of 11-dimensional supergravity for which the contribution of the Chern-Simons term to the field equations is non-zero. After studying…
