  author={Celia Escamilla-Rivera and Geovanny A. Rave-Franco and Jackson Levi Said},
In light of the statistical performance of cosmological observations, in this work we present the cosmography in f(T,B) gravity. In this scenario we found a cosmological viable standard case that allows to reduce the degeneracy between several f(T,B) models already proposed in the literature. Furthermore, we constrain this model using Pantheon SNeIa compilation, Cosmic Chronometers and a newly GRB calibrated data sample. We found that with an appropriate strategy for including the cosmographic…

Black holes in f(T,B) gravity: exact and perturbed solutions
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 for the


Cosmological viable models in f ( T , B ) theory as solutions to the H 0 tension
In this work we present a further investigation about Teleparallel Gravity Cosmology. We demonstrate that according the current astrophysical data (CC+Pantheon+BAO samplers with late universe
A study of the cosmologically reconstructed f(T, B) gravity from the cosmological jerk parameter
The f(T, B) gravity which can also be considered as a natural modification of teleparallel gravity has been successfully used to substitute DE along with providing an explanation for the
Energy constraints and the phenomenon of cosmic evolution in the f(T,B) framework
Abstract.In this paper, we investigate the cosmological evolution in a new modified teleparallel gravity that connects both f(T) and f(R) theories with a boundary term B, called f(T,B) gravity. To
Cosmography in f(T)-gravity
Being based on the only assumption that the universe is homogenous and isotropic on large scales, cosmography is an ideal tool to investigate the cosmic expansion history in a almost
Observational constraints on low redshift evolution of dark energy: How consistent are different observations?
The dark energy component of the Universe is often interpreted either in terms of a cosmological constant or as a scalar field. A generic feature of the scalar field models is that the equation of
Cosmological perturbations in f(T) gravity
We investigate the cosmological perturbations in f(T) gravity. Examining the pure gravitational perturbations in the scalar sector using a diagonal vierbein, we extract the corresponding dispersion
A parametric model for dark energy
Abstract Determining the mechanism behind the current cosmic acceleration constitutes a major question nowadays in theoretical physics. If the dark energy route is taken, this problem may potentially
Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant
We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 " z " 0.62. The luminosity distances of these objects are determined by methods that
Constraining Cosmological Parameters Based on Relative Galaxy Ages
We propose to use relative galaxy ages as a means of constraining cosmological parameters. By measuring the age difference between two ensembles of passively evolving galaxies at somewhat different
