Thermodynamics and information recovery of Schwarzschild AdS black holes in conformal Killing gravity

Yahya Ladghami, Brahim Asfour, Francisco S. N. Lobo +1

We study Schwarzschild AdS black holes in conformal Killing gravity, focusing on their thermodynamics and information recovery via the island formula. Treating the cosmological con…

Gravitational waves production during preheating within GB gravity with monomial coupling

Brahim Asfour, Yahya Ladghami, Taoufik Ouali

In this paper, we investigate the production of gravitational waves during the preheating era. To achieve this purpose, we consider Gauss-Bonnet inflation model with Power{\textend…
