Using thermodynamics to learn gravitational wave physics
Caio César Rodrigues Evangelista, Níckolas de Aguiar Alves
Black holes are some of the most interesting objects in the universe. While they first arise in the complicated behavior of general relativity, the physical laws ruling their behav…
Lower-dimensional Gauss-Bonnet gravity black holes with quintessence
G. Alencar, T. M. Crispim, J. Macedo +1
In this paper, we study the limit of Gauss-Bonnet gravity with quintessential matter, obtaining exact solutions that extend the BTZ metric through higher-curvature terms an…
On regular black string spacetimes in nonlinear electrodynamics
G. Alencar, V. H. U. Borralho, T. M. Crispim +1
In this work, we investigate the coupling of General Relativity with Nonlinear Electrodynamics (NED), governed by a general Lagrangian , to address the ax…
Evolving spatiotemporal patterns and urban scaling of deaths from external causes
Cesar I. N. Sampaio Filho, Humberto A. Carmona, Antonio S. Lima Neto +4
Urban scaling theory posits that urban indicators follow power-law relations with population, yet the evolution of these patterns - and the role of regional differences in settings…
Classical double copy of black strings in an Anti-de Sitter background
G. Alencar, C. R. Muniz, M. S. Oliveira
We study the classical double copy for static black string solutions in an Anti--de Sitter (AdS) background. By casting the black string metric into Kerr--Schild form over a cylind…
Topological Thermodynamics of Black Holes: Revisiting the methods of winding numbers calculation
A. A. M. Silva, G. Alencar, C. R. Muniz +2
In this paper, the equivalence between two methods for computing winding numbers is established: the approach of -mapping topological current and the residue method. The methods…
