Stability of a Schwarzschild Singularity
TLDR
In this article, it was shown that a Schwarzschild singularity, spherically symmetrical and endowed with mass, will undergo small vibrations about the spherical form and therefore remain stable if subjected to a small nonspherical perturbation.Abstract:

BlackHawk: A public code for calculating the Hawking evaporation spectra of any black hole distribution
TL;DR: BlackHawk as discussed by the authors is a C program for calculating the Hawking evaporation spectra of any black hole distribution, which can be used to study the evolution of the distribution of black holes in time.

Complexity in Spacetime and Gravitation i. FromChaos to Superchaosfn2fn2This paper, as a token ofappreciation, is intended to celebrate the 57th birthday of Otto Rössler.
TL;DR: In this paper, the authors propose a multi-spherical cosmic fractal as a model of homogeneous andisotropic cosmologies for the analysis of complex problems in space, time and gravitation.

The cosmological constant as an eigenvalue of a Sturm–Liouville problem and its renormalization
TL;DR: In this article, a variational approach with Gaussian trial wave functions is used as a method to study massive gravitons and their relation with the cosmological constant, considered as an eigenvalue of a Sturm-Liouville problem.

Black Holes in Higher-Dimensional Gravity
TL;DR: In this paper, the phase structure of Kaluza-klein black holes is discussed, including an intriguing connection that relates the phase structures of Kalzu-klein black holes with that of asymptotically flat rotating black holes.

Clean Time-Dependent String Backgrounds from Bubble Baths
TL;DR: In this article, the authors consider a set of controlled time-dependent backgrounds of general relativity and string theory describing ''bubbles of nothing'' obtained via double analytic continuation of black hole solutions.
