Linear perturbation analysis of hairy black holes in shift-symmetric Horndeski theories: Odd-parity perturbations
Kazufumi Takahashi, Teruaki Suyama
We analyze the mode stability of odd-parity perturbations of black holes with linearly time-dependent scalar hair in shift-symmetric Horndeski theories. We show that a large class…
