Primordial black hole production in scalar field inflation within gravity
Daniel Villalobos-Silva, Yerko Vásquez, Giovanni Otalora
We investigate inflation in modified teleparallel gravity within a scalar-tensor framework. We focus on two viable extensions of the Teleparallel Equivalent of General Relativity:…
Time Like Geodesics of Regular Black Holes with Scalar Hair
P. A. González, Marco Olivares, Eleftherios Papantonopoulos +1
We investigate timelike geodesics in asymptotically flat regular black holes supported by a phantom scalar field characterized by a scalar charge . This parameter removes the ce…
Anomalous Decay Rate and Greybody Factors for Regular Black Holes with Scalar Hair
Ramón Bécar, P. A. González, Eleftherios Papantonopoulos +1
We study the propagation of massive scalar fields in the background of asymptotically flat regular black holes supported by a phantom scalar field with a scalar charge . This pa…
Lyapunov Exponents and Phase Transitions in Four-Dimensional AdS Black Holes with a Nonlinear Electrodynamics Source
Ramón Bécar, P. A. González, Felipe Moncada +1
We investigate the relationship between dynamical instability and thermodynamic phase transitions in four-dimensional Anti--de Sitter black holes in Einstein gravity coupled to a n…
