The effects of running gravitational coupling on three dimensional black holes
Angel Rincon, Benjamin Koch, Cristobal Laporte +2
In the present work, we investigate the consequences of running gravitational coupling on the properties of the three-dimensional BTZ black hole. We take as starting point the func…
Cosmological constraints on scale-dependent cosmology
Pedro D. Alvarez, Benjamin Koch, Cristobal Laporte +1
This paper examines a cosmological model of scale-dependent gravity. The gravitational action is taken to be the Einstein-Hilbert term supplemented with a cosmological constant, wh…
Orbits of light rays in (1+2)-dimensional Einstein-power-Maxwell gravity: Exact analytical solution to the null geodesic equations
Grigoris Panotopoulos, Angel Rincon
We study photon orbits within (1+2)-dimensional Einstein-power-Maxwell non-linear electrodynamics assuming a static and circularly symmetric background. An exact analytical solutio…
Binary X-ray sources in massive Brans-Dicke gravity
Grigoris Panotopoulos, Ángel Rincón, Ilídio Lopes
This study focuses on the X-ray emission of low-mass black hole binaries in massive Brans-Dicke gravity. First, we compute the accretion disk adopting the well-known Shakura-Sunyae…
Statefinder analysis of scale-dependent cosmology
Pedro D. Alvarez, Benjamin Koch, Cristobal Laporte +2
We study the statefinder parameters of a cosmological model based on scale-dependent gravity. The effective Einstein field equations come from an average effective action. From the…
Quasinormal modes of massive scalar fields in four-dimensional wormholes: anomalous decay rate
P. A. González, Eleftherios Papantonopoulos, Ángel Rincón +1
In this work we consider a Generalized Bronnikov-Ellis wormhole and the tideless Morris-Thorne wormhole and we study the propagation of massive scalar fields. We calculate the quas…
