An binary black hole algorithm to solve set covering problem
(Springer Verlag, 2016)
Analytic Lifshitz black holes in higher dimensions
(Springer, 2010-04)
We generalize the four-dimensional R2-corrected z = 3/2 Lifshitz black hole to a two-parameter family of black hole solutions for any dynamical exponent z and for any dimension D. For a particular relation between the ...
Supertranslations and Superrotations at the Black Hole Horizon
(American Physical Society, 2016-03-04)
We show that the asymptotic symmetries close to nonextremal black hole horizons are generated by an extension of supertranslations. This group is generated by a semidirect sum of Virasoro and Abelian currents. The charges ...
Gravitational lensing by massless braneworld black holes
(American Physical Society, 2012-10)
In this paper, we study massless braneworld black holes as gravitational lenses. We find the weak and the strong deflection limits for the deflection angle, from which we calculate the positions and magnifications of the ...
Comment on" Boosted Kerr black holes in general relativity"
(American Physical Society, 2020-01)
We discuss a recently presented boosted Kerr black hole solution which had already been used by other authors. This boosted metric is based on wrong assumptions regarding asymptotic inertial observers and moreover the ...
VACUUM POLARIZATION EFFECTS ON QUASINORMAL MODES IN ELECTRICALLY CHARGED BLACK HOLE SPACE-TIMES
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
We investigate the influence of vacuum polarization of quantum massive fields on the scalar sector of quasinormal modes in spherically symmetric black holes. We consider the evolution of a massless scalar field on the ...
Neutral regular black hole solution in generalized Rastall gravity
(Iop Publishing Ltd, 2019-08-01)
We investigate the static, spherically symmetric regular black hole solutions in the generalized Rastall gravity. In particular, the prescription of Rastall gravity implies that the present approach does not necessarily ...
Numerical estimates of the accretion rate on to intermediate-mass black holes
(Wiley Blackwell Publishing, Inc, 2013-04)
The existence of intermediate-mass (∼103 M⊙) black holes (IMBHs) in the centre of glob- ular clusters has been suggested by different observations. The X-ray sources observed in NGC 6388 and in G1 in M31 could be interpreted ...
