# Magnetized strange quark model with Big Rip singularity in $f(R,T)$ gravity

## TL;DR

This paper develops a cosmological model within $f(R,T)$ gravity featuring magnetized strange quark matter, demonstrating a transition from deceleration to acceleration and ending in a Big Rip, consistent with observational data.

## Contribution

It presents an exact solution for a magnetized strange quark matter cosmology in $f(R,T)$ gravity with a linearly varying deceleration parameter, aligning with recent observational findings.

## Key findings

- The model begins with a Big Bang and ends in a Big Rip.
- The deceleration parameter transitions from decelerating to accelerating, matching observations.
- The Hubble parameter and distance modulus are consistent with redshift data.

## Abstract

LRS (Locally Rotationally symmetric) Bianchi type-I magnetized strange quark matter cosmological model have been studied based on $f(R,T)$ gravity. The exact solutions of the field equations are derived with linearly time varying deceleration parameter which is consistent with observational data (from SNIa, BAO and CMB) of standard cosmology. It is observed that the model start with big bang and ends with a Big Rip. The transition of deceleration parameter from decelerating phase to accelerating phase with respect to redshift obtained in our model fits with the recent observational data obtained by Farook et al. in 2017. The well known Hubble parameter $H(z)$ and distance modulus $\mu(z)$ are discussed with redshift.
