Bounds on tidal charges from gravitational-wave ringdown observations
Akash K Mishra, Gregorio Carullo, Sumanta Chakraborty
Black hole solutions in the braneworld scenario are predicted to possess a tidal charge parameter, leaving imprints in the quasinormal spectrum. We conduct an extensive computation…
