Octupolar Gravitational Radiation in de Sitter Spacetime

Harsh, Omkar Shetye, Amitabh Virmani

We derive the gravitational radiation generated by a localised matter source in de Sitter spacetime at octupolar order in the multipolar expansion, working in generalised harmonic…

Index saddle for the D1-D5-P black string and its decoupling limit

Kanhu Kishore Nanda, P Shanmugapriya, Amitabh Virmani

Boruch, Emparan, Iliesiu, and Murthy recently discussed index saddles for 5d black strings, showing that the black string saddle admits a decoupling limit to a complex, finite-temp…

Index saddle for supersymmetric F1-P black ring

Pavan Dharanipragada, Gurmeet Singh Punia, Amitabh Virmani

We construct the index saddle for the supersymmetric F1--P black ring. Our construction proceeds by taking a supersymmetric limit of a non-supersymmetric doubly spinning F1--P blac…

Non-supersymmetric F1-P black rings

Pavan Dharanipragada, Gurmeet Singh Punia, Amitabh Virmani

We construct singly and doubly spinning non-supersymmetric F1--P black ring solutions in five-dimensional supergravity. These black rings have regular horizons and non-zero tempera…

BPS Solutions of 4d Euclidean N=2 Supergravity with Higher Derivative Interactions

Soumya Adhikari, Abhinava Bhattacharjee, Amitabh Virmani

We study fully BPS and a broad class of half-BPS stationary configurations of four-dimensional Euclidean N=2 supergravity with higher-derivative interactions. Working within the of…

The gravitational index of a small black ring

Subhodip Bandyopadhyay, Gurmeet Singh Punia, Yogesh K. Srivastava +1

Certain supersymmetric elementary string states with angular momentum can be viewed as small black rings in a five-dimensional string theory. These black rings have zero area event…
