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…

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…
