Dynamics of scalar perturbations in f(R, T) gravity
F. G. Alvarenga,A. de la Cruz-Dombriz,M. J. S. Houndjo,Manuel E. Rodrigues,Manuel E. Rodrigues,Diego Sáez-Gómez +5 more
TL;DR: In this article, the evolution of scalar cosmological perturbations in the metric formalism is studied in the context of f(R, T) theories of gravity, where a specific model within these theories is assumed in order to guarantee the standard continuity equation.
Journal ArticleDOI
Black holes, cosmological solutions, future singularities, and their thermodynamical properties in modified gravity theories
TL;DR: This review focuses on the study of several properties of modified gravity theories, in particular on black-hole solutions and its comparison with those solutions in General Relativity, and on Friedmann-Lemaitre-Robertson-Walker metrics.
Journal ArticleDOI
Black Holes in f(R) theories
TL;DR: In this paper, a perturbative approach around the Einstein-Hilbert action was used to find static and spherically symmetric black hole solutions in f(R) theories of gravity.

TL;DR: The Square Kilometre Array (SKA) is a planned large radio interferometer designed to operate over a wide range of frequencies, and with an order of magnitude greater sensitivity and survey speed than any current radio telescope as mentioned in this paper.
Journal ArticleDOI
Evolution of density perturbations in f(R) theories of gravity
TL;DR: In this paper, the evolution of scalar cosmological perturbations in the metric formalism was studied in the context of f(R) theories of gravity, and the exact fourth-order differential equation for the matter density perturbation in the longitudinal gauge was derived.
