Overcharging Extremal Rotating Black Holes

Shauvik Biswas, Amruta Sadhu, Sudipta Sarkar

In this work, we use the weak cosmic censorship conjecture(WCC) to constrain black hole solutions in modified gravity theories. While Wald showed that extremal Kerr-Newman black ho…

Study of Semiclassical Instability of the Schwarzschild AdS Black Hole in the Large Limit

Amruta Sadhu, Vardarajan Suneeta

We analyze the semiclassical stability of the Schwarzschild AdS black hole in the Euclidean partition function approach. We perform this computation in the large limit and focu…

Schwarzschild-Tangherlini quasinormal modes at large revisited

Amruta Sadhu, Vardarajan Suneeta

The large dimension () limit of general relativity has been used in problems involving black holes as an analytical approximation tool. Further it has been proposed that both li…

Non-spherically symmetric black string perturbations in the large D limit

Amruta Sadhu, Vardarajan Suneeta

We consider non-spherically symmetric perturbations of the uncharged black string/flat black brane in the large dimension (D) limit of general relativity. We express the perturbati…

A naked singularity stable under scalar field perturbations

Amruta Sadhu, V. Suneeta

We prove the stability of a spacetime with a naked singularity under scalar field perturbations, where the perturbations are regular at the singularity. This spacetime, found by Ja…
