Cosmic acceleration and phantom crossing in $f(T)$-gravity

TL;DR

This paper introduces two new $f(T)$ gravity models that explain cosmic acceleration and phantom crossing, supported by observational data indicating a universe that accelerates with potential phantom crossing in the near past or future.

Contribution

The paper proposes novel $f(T)$ gravity models that account for universe acceleration and phantom crossing, with observational constraints and tests.

Findings

Best fit results favor an accelerating universe.

Models allow for phantom crossing in the near past or future.

Supports dark torsion as a driver of cosmic acceleration.

Abstract

In this paper, we propose two new models in $f(T)$ gravity to realize universe acceleration and phantom crossing due to dark torsion in the formalism. The model parameters are constrained and the observational test are discussed. The best fit results favors an accelerating universe with possible phantom crossing in the near past or future followed respectively by matter and radiation dominated era.
