Accretion with Back-Reaction onto Cylindrically Symmetric Black Hole with Energy Conditions Analysis

Abstract

This paper is devoted to study back-reaction effects from matter accretion onto a cylindrically symmetric black hole using a perturbative scheme, focusing on cases where accretion reaches a quasi-steady state. We examine three distinct models by deriving corrections to the metric coefficients and obtaining expressions for the mass function. We analyze energy conditions, the self-consistency of the corrected solution and present formulas for the corrected apparent horizon and discussed thermodynamic properties. Our results align with the Vaidya form near the apparent horizon, regardless of the energy-momentum tensor's form. Furthermore, we show that for a charged cylindrically symmetric black hole, the corrected mass term resembles that of the static case, indicating that charge does not alter the corrected metric form in this perturbative approach.
