Brazilian Community Report on Dark Matter
E. Abdalla, I. F. M. Albuquerque, A. Alves +52
This white paper summarizes the activities of the Brazilian community concerning dark matter physics and highlights the importance of financial support to Brazilian groups that are…
On quasinormal modes for the Vaidya metric in asymptotically anti-de Sitter spacetime
Kai Lin, Yunqi Liu, Wei-Liang Qian +2
In this work, we present a numerical scheme to study the quasinormal modes of the time-dependent Vaidya black hole metric in asymptotically anti-de Sitter spacetime. The proposed a…
Instability of Reissner-Nordström-AdS black hole under perturbations of a scalar field coupled to Einstein tensor
E. Abdalla, B. Cuadros-Melgar, R. D. B. Fontana +3
We study the instability of a Reissner-Nordström-AdS (RNAdS) black hole under perturbations of a massive scalar field coupled to Einstein tensor. Calculating the potential of the s…
J-PAS: forecasts on interacting dark energy from baryon acoustic oscillations and redshift-space distortions
A. A. Costa, R. J. F. Marcondes, R. G. Landim +14
We estimate the constraining power of J-PAS for parameters of an interacting dark energy cosmology. The survey is expected to map several millions of luminous red galaxies, emissio…
