Analyzing Quasi-normal modes spectrum in asymptotically de Sitter black bounces and their optical appearance
G. Alencar, Albert Duran-Cabacés, A. Lima +2
This work explores asymptotically de Sitter black-bounce spacetimes, obtained as a regular extension of the Schwarzschild-de Sitter geometry via the Simpson-Visser prescription. Th…
Quasinormal modes of a quantum inspired black hole in four dimensions with cosmological constant
R. D. B. Fontana, Jeferson de Oliveira, B. Eslam Panah +1
We study the scalar and Dirac perturbations of quantum-corrected black holes with cosmological constant. Using two different methods (WKB and double-null characteristic integration…
The gravitational wave-black hole imaging correspondence for modified black holes
David Díaz-Guerra, Ángel Rincón, Diego Rubiera-Garcia +1
Black holes (BHs) can be studied via fundamentally different observational channels that probe complementary aspects of their physics. While BH imaging provides access to the quasi…
Observational appearance and photon rings of non-singular black holes from anisotropic fluids
David Díaz-Guerra, Angel Rincon, Diego Rubiera-Garcia
We consider the optical appearance of a non-singular, spherically symmetric black hole from Eddington-inspired Born-Infeld gravity coupled to anisotropic fluids. Such a black hole…
Quasinormal modes and emission rate of ModMax (A)dS black holes
Behzad Eslam Panah, Angel Rincon, Narges Heidari
By considering a new model of nonlinear electrodynamics, known as the modified Maxwell (ModMax), and taking into account the topological and the cosmological constants in Einstein'…
Accelerated black holes in (2+1) dimensions: Quasinormal modes and Stability
R. D. B. Fontana, Angel Rincon
We investigate the propagation of a scalar field in a -dimensional accelerated black hole, recently revisited in \cite{Arenas_Henriquez_2022}. We briefly describe the minima…
