4D scale-dependent Schwarzschild-AdS/dS black holes: study of shadow and weak deflection angle and greybody bounding

A Övgün, RC Pantig, Á Rincón - The European Physical Journal Plus, 2023 - Springer
We investigate the shadow, deflection angle, and the greybody bounding of a Schwarzschild-

Stability of asymptotically de Sitter and anti-de Sitter black holes in 4D regularized Einstein–Gauss–Bonnet theory

MA Cuyubamba - Physics of the Dark Universe, 2021 - Elsevier
A regularized four-dimensional Einstein–Gauss–Bonnet model has been recently proposed

derive the Teukolsky equations for massless fields of all spins in general spherically …

Greybody factor and quasinormal modes of Regular Black Holes

Á Rincón, V Santos - The European Physical Journal C, 2020 - Springer
In this work, we investigate the quasinormal frequencies of a class of regular black hole
solutions which generalize Bardeen and Hayward spacetimes. In particular, we analyze …

Bending of light in novel 4D Gauss-Bonnet-de Sitter black holes by the Rindler-Ishak method
