f (T) teleparallel gravity and cosmology

YF Cai, S Capozziello, M De Laurentis… - Reports on Progress …, 2016 - iopscience.iop.org
Over recent decades, the role of torsion in gravity has been extensively investigated along
the main direction of bringing gravity closer to its gauge formulation and incorporating spin …

The covariant formulation of f (T) gravity

M Krššák, EN Saridakis - Classical and Quantum Gravity, 2016 - iopscience.iop.org
We show that the well-known problem of frame dependence and violation of local Lorentz
invariance in the usual formulation of f (T) gravity is a consequence of neglecting the role of …

Model-independent reconstruction of f (T) gravity from Gaussian Processes

YF Cai, M Khurshudyan… - The Astrophysical …, 2020 - iopscience.iop.org
We apply Gaussian processes and Hubble function data in f (T) cosmology to reconstruct for
the first time the f (T) form in a model-independent way. In particular, using H (z) data sets …

Bayesian analysis of gravity using data

FK Anagnostopoulos, S Basilakos, EN Saridakis - Physical Review D, 2019 - APS
We use observational data from the Pantheon supernovae sample, direct Hubble constant
measurements with cosmic chronometers, the cosmic microwave background shift …

Gravitational waves in modified teleparallel theories

G Farrugia, JL Said, V Gakis, EN Saridakis - Physical Review D, 2018 - APS
We investigate the gravitational waves and their properties in various modified teleparallel
theories, such as f (T), f (T, B), and f (T, TG) gravities. We perform the perturbation analysis …

New observational constraints on f (T) gravity from cosmic chronometers

RC Nunes, S Pan, EN Saridakis - Journal of Cosmology and …, 2016 - iopscience.iop.org
We use the local value of the Hubble constant recently measured with 2.4% precision, as
well as the latest compilation of cosmic chronometers data, together with standard probes …

Bounce inflation in cosmology: A unified inflaton-quintessence field

K Bamba, GGL Nashed, W El Hanafy, SK Ibraheem - Physical Review D, 2016 - APS
We investigate a bounce inflation model with a graceful exit into the Friedmann-Robertson-
Walker (FRW) decelerated Universe within f (T)-gravity framework, where T is the torsion …

Rotating AdS black holes in Maxwell-f (T) gravity

GGL Nashed, EN Saridakis - Classical and Quantum Gravity, 2019 - iopscience.iop.org
The investigation on higher-dimensional AdS black holes is of great importance under the
light of AdS/CFT correspondence. In this work we study static and rotating, uncharged and …

gravitational baryogenesis

VK Oikonomou, EN Saridakis - Physical Review D, 2016 - APS
We investigate how baryogenesis can occur by the presence of an f (T)-related gravitational
term. We study various cases of f (T) gravity, and we discuss in detail the effect of the novel …

Generalized energy-momentum-squared gravity in the Palatini formalism

E Nazari, F Sarvi, M Roshan - Physical Review D, 2020 - APS
We study the generalized version of energy-momentum squared gravity (EMSG) in the
Palatini formalism. This theory allows the existence of a scalar constructed with energy …
