Mode stability of a near-extremal Kerr superspinar

Rittick Roy, Prashant Kocherlakota, Pankaj S. Joshi

We study here the quasi-normal mode stability of a near-extremal Kerr superspinar, an exotic spinning compact object that exceeds the Kerr bound, under gravitational perturbations.…

Evolution of black hole shadow in the presence of ultralight bosons

Rittick Roy, Urjit A. Yajnik

Kerr black holes coupled to quantized bosonic fields display a special version of the Hawking effect, governed by the superradiance condition. This leads to rapid growth of boson c…
