Mass inflation and strong cosmic censorship in a nonextreme BTZ black hole

Abstract

We study the phenomena of mass inflation using the Ori model for a rotating Bañados-Teitelboim-Zanelli (BTZ) black hole that is sufficiently far from extremality, and show that the right Cauchy horizon (CHR+) of the BTZ black hole becomes singular. Motivated by the recent analysis of Dias, Reall, Santos [J. High Energy Phys. 12 (2019) 097JHEPFG1029-847910.1007/JHEP12(2019)097], we choose the retrograde quasinormal modes to govern the decay of perturbations exterior to the black hole. The resulting model captures the violation of the strong cosmic censorship conjecture near extremality. On the other hand, far from extremality, the CHR+ of a BTZ black hole develops a weak null singularity. Our analysis shows a slowly rotating BTZ black hole will respect strong cosmic censorship.

I am currently working as a Post-Doctoral Fellow at IIT Kharagpur, India. My research interests broadly lie in the field of various aspects of gravitation theory, with a particular focus on black holes and gravitational waves (GWs). My current research encompasses black hole perturbation techniques, extreme mass-ratio inspirals (EMRIs), gravitational memory, tidal effects and post-Newtonian framework.
