Theory-agnostic searches for non-gravitational modes in black hole ringdown
Francesco Crescimbeni, Xisco Jimenez Forteza, Swetha Bhagwat +2
In any extension of General Relativity (GR), extra fundamental degrees of freedom couple to gravity. Besides deforming GR forecasts in a theory-dependent way, this coupling generic…
