Black hole mergers beyond general relativity: a self-force approach
Ayush Roy, Lorenzo Küchler, Adam Pound +1
Gravitational waves from binary black hole mergers provide a glimpse of gravitational dynamics in its most extreme observable regime, potentially enabling precision tests of genera…

Shadows of rotating hairy Kerr black holes coupled to time periodic scalar fields with non-flat target space
Galin N. Gyulchev, Ayush Roy, Lucas G. Collodel +3
We study the shadows cast by rotating hairy black holes with two non-trivial time-periodic scalar fields having a non-flat Gaussian curvature of the target space spanned by the sca…
