Non-minimal light-curvature couplings and black-hole imaging
Raúl Carballo-Rubio, Héloïse Delaporte, Astrid Eichhorn +1
Non-minimal couplings between the electromagnetic field strength and the spacetime curvature are part of the effective field theory of gravity and matter. They alter the local prop…
The principled-parameterized approach to gravitational collapse
Héloïse Delaporte, Astrid Eichhorn
New physics beyond General Relativity impacts black-hole spacetimes. The effects of new physics can be investigated in a largely theory-agnostic way by following the principled-par…
Disentangling photon rings beyond General Relativity with future radio-telescope arrays
Raúl Carballo-Rubio, Héloïse Delaporte, Astrid Eichhorn +1
New physics beyond General Relativity can modify image features of black holes and horizonless spacetimes and increase the separation between photon rings. This motivates us to exp…
Parameterizations of black-hole spacetimes beyond circularity
Héloïse Delaporte, Astrid Eichhorn, Aaron Held
We discuss parameterizations of black-hole spacetimes in and beyond General Relativity in view of their symmetry constraints: within the class of axisymmetric, stationary spacetime…
