Linearized gravity and soft graviton theorem in de Sitter spacetime
Pujian Mao, Bochen Zhou
We study the linearized gravity theory in the Newman-Unti gauge in the near horizon region of the de Sitter spacetime. The linearized Einstein equation involves the cosmological co…

Near horizon linearized gravity and soft theorem
Pujian Mao, Kai-Yu Zhang, Bochen Zhou
In this paper, we study the linearized gravity theory in the near horizon region of the Schwarzschild black hole in four dimensional spacetime. Under the Newman-Unti gauge, we deri…
