Gravitational wave cosmology in Einstein-scalar-Gauss-Bonnet gravity
Jared Fier, Henry Han, Bowen Li +3
In the framework of Einstein-scalar-Gauss-Bonnet (EsGB) gravity, we systematically study gravitational waves (GWs), first produced by remote compact astrophysical sources and then…
Even-parity black hole perturbations in Minimal Theory of Bigravity
Masato Minamitsuji, Shinji Mukohyama, Michele Oliosi
We study even-parity black hole perturbations in Minimal Theory of Bigravity (MTBG). We consider the Schwarzschild solution written in the spatially-flat coordinates in the self-ac…
Even- and odd-parity stabilities of black holes in Einstein-Aether gravity
Antonio De Felice, Shinji Mukohyama, Shinji Tsujikawa +2
In Einstein-Aether theories with a timelike unit vector field, we study the linear stability of static and spherically symmetric black holes against both even- and odd-parity pertu…
Revisiting linear stability of black hole odd-parity perturbations in Einstein-Aether gravity
Shinji Mukohyama, Shinji Tsujikawa, Anzhong Wang
In Einstein-Aether gravity, we revisit the issue of linear stabilities of black holes against odd-parity perturbations on a static and spherically symmetric background. In this the…
