Abstract: 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… read more here.

Abstract: We have previously presented a reconstruction of Horndeski scalar-tensor theories from linear cosmological observables. It includes free nonlinear terms which can be added onto the reconstructed covariant theory without affecting the background and linear dynamics.… read more here.
