Cosmological constant problem: deflation during inflation
Felipe Canales, Benjamin Koch, Cristobal Laporte +1
We argue that the discrepancy between the Planck mass scale and the observed value of the cosmological constant can be largely attenuated if those quantities are understood as a re…
Greybody factors and quasinormal modes for a nonminimally coupled scalar field in a cloud of strings in (2+1)-dimensional background
Ángel Rincón, Grigoris Panotopoulos
We study the propagation of a probe massless nonminimally coupled scalar field in a fixed gravitational background of a cloud of strings in (2+1) dimensions. We obtain exact analyt…
Minimal Geometric Deformation in a cloud of strings
Grigoris Panotopoulos, Ángel Rincón
We find new exact analytical solutions in three-dimensional gravity applying the Minimal Geometric Deformation approach in a cloud of strings.
Relativistic dust accretion onto a scale--dependent polytropic black hole
Ernesto Contreras, Ángel Rincón, J. M. Ramírez-Velasquez
In this work we study steady and spherical relativistic dust accretion onto a static and spherically symmetric scale--dependent black hole. In particular we consider a polytropic s…
Charged slowly rotating toroidal black holes in the (1+3)-dimensional Einstein-power-Maxwell theory
Grigoris Panotopoulos, Angel Rincon
In this work we find charged slowly rotating solutions in the four-dimensional Einstein-power-Maxwell non-linear electrodynamics assuming a negative cosmological constant. By solvi…
Scale-dependent (2+1) - dimensional electrically charged black holes in Einstein-power-Maxwell theory
Angel Rincon, Ernesto Contreras, Pedro Bargueño +2
In this work we extend and generalize our previous work on the scale dependence at the level of the effective action of black holes in the presence of non-linear electrodynamics. I…
