Massive spin-2 and spin-1/2 no hair theorems for stationary axisymmetric black holes
Sourav Bhattacharya, Amitabha Lahiri
We present a proof of the no hair theorems corresponding to free massive non-perturbative Pauli-Fierz spin-2 and perturbative massive spin-1/2 fields for stationary axisymmetric de…
No hair theorems for stationary axisymmetric black holes
Sourav Bhattacharya, Amitabha Lahiri
We present a non-perturbative proof of the no hair theorems corresponding to scalar and Proca fields for stationary axisymmetric de Sitter black hole spacetimes. Our method also ap…
Effect of a positive cosmological constant on cosmic strings
Sourav Bhattacharya, Amitabha Lahiri
We study cosmic Nielsen-Olesen strings in space-times with a positive cosmological constant. For the free cosmic string in a cylindrically symmetric space-time, we calculate the co…
No hair theorems for positive Λ
Sourav Bhattacharya, Amitabha Lahiri
We extend all known black hole no-hair theorems to space-times endowed with a positive cosmological constant Specifically, we prove that static spherical black holes with $Λ>0…
