Dynamics of cylindrical collapse in [formula omitted] gravity

Abstract

This paper investigates the dynamics of cylindrical collapse with perfect fluid distribution in the background of curvature-matter coupled gravity. Using Misner-Sharp technique, we construct dynamical equations which lead to analyze the effects of correction terms and fluid parameters on the collapse process. A correlation between correction terms, fluid parameters and the Weyl scalar is also formulated. In the case of constant f(G,T) model, it is concluded that homogeneity of energy density yields the conformal flatness and vice-versa. We find that the collapse rate is reduced due to anti-gravitational behavior of the correction terms.
