Energy of asymptotically AdS black holes in Exotic Massive Gravity and its log-extension
Robert B. Mann, Julio Oliva, S. N. Sajadi
Recently a new three-dimensional theory of gravity, dubbed Exotic Massive Gravity, was proposed as a unitary theory both in the bulk as well as in the dual CFT. This is the second…
Snapping swallowtails in accelerating black hole thermodynamics
Niloofar Abbasvandi, Wan Cong, David Kubiznak +1
The thermodynamic behaviour of a charged and accelerating AdS black hole is studied in the context of extended phase space with variable cosmological constant. When compared to the…
Energy-momentum tensor and metric near the Schwarzschild sphere
Valentina Baccetti, Robert B. Mann, Sebastian Murk +1
Regularity of the horizon radius of a collapsing body constrains a limiting form of a spherically-symmetric energy-momentum tensor near it. Its non-zero limit belongs to one…
Intrinsic curvature and topology of shadows in Kerr spacetime
Shao-Wen Wei, Yu-Xiao Liu, Robert B. Mann
From the viewpoint of differential geometry and topology, we investigate the characterization of the shadows in a Kerr spacetime. Two new quantities, the length of the shadow bound…
Gravitational Lensing by Black Holes in Einsteinian Cubic Gravity
Mohammad Bagher Jahani Poshteh, Robert B. Mann
We investigate the predictions of Einsteinian Cubic Gravity (ECG) for the lensing effects due to supermassive black holes at the center of Milky Way and other galaxies. Working in…
Shadow and Deflection Angle of Rotating Black Holes in Perfect Fluid Dark Matter with a Cosmological Constant
Sumarna Haroon, Mubasher Jamil, Kimet Jusufi +2
The presence of dark matter around a black hole remarkably affects its spacetime. We consider the effects of dark matter on the shadow of a new solution to the Einstein equations t…
