Constraints on f(T) cosmology with Pantheon+

R Briffa, C Escamilla-Rivera, JL Said… - Monthly Notices of the …, 2023 - academic.oup.com
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 …

[HTML][HTML] Strengthening extended gravity constraints with combined systems: f (R) bounds from cosmology and the galactic center

D Benisty, J Mifsud, JL Said, D Staicova - Physics of the Dark Universe, 2023 - Elsevier
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 …

Quasinormal modes of black holes in f (T) gravity

Y Zhao, X Ren, A Ilyas, EN Saridakis… - Journal of Cosmology …, 2022 - iopscience.iop.org
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) …

Black hole solutions in scalar-tensor symmetric teleparallel gravity

S Bahamonde, JG Valcarcel, L Järv… - Journal of Cosmology …, 2022 - iopscience.iop.org
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 …

Reconstructing teleparallel gravity with cosmic structure growth and expansion rate data

JL Said, J Mifsud, J Sultana… - Journal of Cosmology and …, 2021 - iopscience.iop.org
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-wave propagation and polarizations in the teleparallel analog of Horndeski gravity

S Bahamonde, M Hohmann, M Caruana… - Physical Review D, 2021 - APS
Gravitational waves (GWs) have opened a new window on fundamental physics in a number

Dark energy interactions near the Galactic Center

D Benisty, AC Davis - Physical Review D, 2022 - APS
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 …
