Strong-field Gravitational Wave Lensing in the Kerr Background
M. V. S. Saketh, Rajes Ghosh, Anuj Mishra
Gravitational-wave (GW) lensing can encode valuable information about the properties of the intervening lens, but most existing studies remain restricted to the small-deflection, w…
Kerr-Newman quasinormal modes and Seiberg-Witten theory
Hector O. Silva, Jung-Wook Kim, M. V. S. Saketh
It was recently suggested the quasinormal-mode spectrum of black holes is related to a class of four-dimensional super Yang-Mills theories described by Seiberg-Witt…
Conservative and radiative dynamics in classical relativistic scattering and bound systems
M. V. S. Saketh, Justin Vines, Jan Steinhoff +1
As recent work continues to demonstrate, the study of relativistic scattering processes leads to valuable insights and computational tools applicable to the relativistic bound-orbi…
Torsion driven Inflationary Magnetogenesis
M. V. S. Saketh, R. Kothari, P. Jain
We show that breaking of the conformal invariance of electromagnetic Lagrangian which is required for inflationary magnetogenesis arises naturally in the Poincar{é} Gauge Theory. W…
