Axial black hole perturbations in purely-metric Horndeski theories
Héloïse Delaporte, Hugo Roussille
We study axial (odd-parity) perturbations about static and spherically-symmetric curvaturised black hole solutions of purely-metric Horndeski theories. We first review the construc…
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…
