Iterative Solution of the Kerr Black Hole Metric
Poul H. Damgaard, Hojin Lee, Kanghoon Lee +1
Using a recursive solution of the Einstein equations, we consider the perturbative expansion of the metric corresponding to a Kerr black hole. Because the metric is a function of t…
Gravitational Metric of a Star
Poul H. Damgaard, Hojin Lee, Kanghoon Lee +1
Solving the classical equations of motion in general relativity recursively, we consider the metric of a spatially localized and stationary source of matter. Having in mind a star…
AdS S-Matrix for Massive Vector Fields
Nabamita Banerjee, Amogh Neelkanth Desai, Karan Fernandes +2
We generalize a recent ``AdS S-matrix" formulation for interacting massive scalars on AdS spacetimes to the case of massive vector fields. This method relies on taking the infinite…
Asymptotic Symmetry algebra of Supergravity
Nabamita Banerjee, Tabasum Rahnuma, Ranveer Kumar Singh
The asymptotic symmetry algebra of supergravity was recently constructed using the well-known D celestial CFT (CCFT) technique in ArXiv: 2007.03785. In this pape…
Soft and Collinear Limits in Supergravity using Double Copy Formalism
Nabamita Banerjee, Tabasum Rahnuma, Ranveer Kumar Singh
It is known that supergravity is dual to super Yang-Mills (SYM) via the double copy relation. Using the explicit relation between scattering amplitu…
Asymptotic Symmetry of Four Dimensional Einstein-Yang-Mills and Einstein-Maxwell Theory
Nabamita Banerjee, Tabasum Rahnuma, Ranveer Kumar Singh
Asymptotic symmetry plays an important role in determining physical observables of a theory. Recently, in the context of four dimensional asymptotically flat pure gravity and $\mat…
