Spherically symmetric solutions of theories of gravity built one fundamental class of solutions to describe compact objects like black holes and stars. Moreover, they serve as starting point …
ABSTRACT f (T) cosmology has shown promise in explaining aspects of cosmic evolution. In this work, we analyse constraints on leading models of f (T) gravity in the context of the …
Extended gravity is widely constrained in different astrophysical and astronomical systems. Since these different systems are based on different scales it is not trivial to get a combined …

We calculate the quasinormal modes (QNM) frequencies of a test massless scalar field and an electromagnetic field around static black holes in f (T) gravity. Focusing on quadratic f (T) …
Symmetric teleparallel gravity is constructed with a nonzero nonmetricity tensor while both torsion and curvature are vanishing. In this framework, we find exact scalarised spherically …
In this work, we use a combined approach of Hubble parameter data together with redshift- space-distortion (fσ 8) data, which together are used to reconstruct the teleparallel gravity …
Gravitational waves (GWs) have opened a new window on fundamental physics in a number of important ways. The next generation of GW detectors may reveal more information about …

We investigate scalar-tensor theories, motivated by dark energy models, in the strong gravity regime around the black hole at the center of our galaxy. In such theories general relativity is …
