Forest management intensity affects aquatic communities in artificial tree holes
(Public Library of Science, 2016-05)
Forest management could potentially affect organisms in all forest habitats. However, aquatic communities in water-filled tree-holes may be especially sensitive because of small population sizes, the risk of drought and ...
(Non-adiabatic) string creation on nice slices in Schwarzschild black holes
(2017-04-01)
Nice slices have played a pivotal role in the discussion of the black hole information paradox as they avoid regions of strong spacetime curvature and yet smoothly cut through the infalling matter and the outgoing Hawking ...
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 ...
Quasitopological electromagnetism and black holes
(American Physical Society, 2020-06)
In this paper we extend the quasitopological electromagnetism, recently introduced by H.-S. Liu et al. [arXiv:1907.10876], to arbitrary dimensions by introducing a fundamental p-form field. This allows us to construct new ...
An Extreme Rotating Black Hole in New Massive Gravity Theory

Black hole memory effect
(American Physical Society, 2018-12)
We compute the memory effect produced at the black hole horizon by a transient gravitational shock wave. As shown by Hawking, Perry, and Strominger (HPS) such a gravitational wave produces a deformation of the black hole ...
Evolution of perturbations of squashed Kaluza-Klein black holes: Escape from instability
(AMER PHYSICAL SOC, 2008)
The squashed Kaluza-Klien (KK) black holes differ from the Schwarzschild black holes with asymptotic flatness or the black strings even at energies for which the KK modes are not excited yet, so that squashed KK black holes ...
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 ...
Strong deflection lensing by charged black holes in scalar-tensor gravity
(Springer, 2014-11)
We examine a class of charged black holes in scalar-tensor gravity as gravitational lenses. We find the deflection angle in the strong deflection limit, from which we obtain the positions and the magnifications of the ...
