Euclidean Thermodynamics and Lyapunov Exponents of Einstein-Power-Yang-Mills AdS Black Holes

Karthik R., Dillirajan D., K. M. Ajith +3

We study the thermodynamics of Einstein-Power-Yang-Mills AdS black holes via the Euclidean path integral method, incorporating appropriate boundary and counterterms. By analyzing u…

Thermodynamics, photon sphere and thermodynamic geometry of Ayón-Beato-García Spacetime

Kartheek Hegde, A. Naveena Kumara, C. L. Ahmed Rizwan +3

We study the thermodynamics of the Ayón-Beato-García black hole and the relationship between photon orbits and the thermodynamic phase transitions of the black hole in AdS spacet…

Spinning LQG black hole as a particle accelerator

Ullas P. Suresh, Karthik R, K. M. Ajith +3

We demonstrate that the spinning LQG black hole can act as a cosmic particle accelerator. The LQG solution is singularity-free and can possess spin greater than that of a Kerr blac…

Greybody factor for an electrically charged regular-de Sitter black holes in -dimensions

Md Sabir Ali, A. Naveena Kumara, Kartheek Hegde +3

We investigate the propagation of scalar fields in the gravitational background of higher-dimensional, electrically charged, regular de Sitter black holes. Using an approximate ana…

Perturbations of Black Holes Surrounded by Anisotropic Matter Field

Sagar J C, Karthik R, Katheek Hegde +3

Our research aims to probe the anisotropic matter field around black holes using black hole perturbation theory. Black holes in the universe are usually surrounded by matter or fie…
