Search for gravitational wave ringdowns from perturbed intermediate mass black holes in LIGO-Virgo data from 2005-2010
(2014)
We report results from a search for gravitational waves produced by perturbed intermediate mass black holes (IMBH) in data collected by LIGO and Virgo between 2005 and 2010. The search was sensitive to astrophysical sources ...

Dynamical black hole in a bouncing universe
(American Physical Society, 2021-03)
We analyze the causal structure of McVittie spacetime for a classical bouncing cosmological model. In particular, we compute the trapping horizons of the metric and integrate the trajectories of radial null geodesics before, ...
Vacíos cósmicos como laboratorios cosmológicos
(2021)
Los extensos vacíos cósmicos (voids) presentes en la estructura a gran escala del Universo constituyen sistemas físicos ideales para estudiar el fenómeno de la energía oscura, uno de los misterios fundamentales de la ...
BTZ black hole with Korteweg-de Vries-type boundary conditions: Thermodynamics revisited
(Facultad de Ingeniería y Tecnología, 2019)
The thermodynamic properties of the Bafiados-Teitelboim-Zanelli black hole endowed with Korteweg-de Vries (KdV)-type boundary conditions are reconsidered. This family of boundary conditions is labeled by a non-negative ...
