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-Docotral Fellow (N-PDF) at the Indian Institute of Technology, Gandhinagar, India. My research interest encompasses various aspects of gravitation theory, broadly black holes and gravitational waves. I am currently working on projects related to black hole perturbation techniques, extreme mass-ratio inspirals (EMRIs), tidal effects and post-Newtonian framework. My work during the PhD provides an understanding of the gravitational memory effect emerging near the horizon of black holes and its connection with asymptotic symmetries. I am also exploring the possibilities to have observational signatures of such symmetries.
