Exploring the construction of field equations for regular black holes with dynamical regularization scales
Raúl Carballo-Rubio, Jacopo Mazza
The study of the dynamics of regular black holes is an emergent area of research. Recent works have discussed how to deform the Einstein field equations to regularize spherically s…
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…
Towards a Non-singular Paradigm of Black Hole Physics
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +18
The study of regular black holes and black hole mimickers as alternatives to standard black holes has recently gained significant attention, driven both by the need to extend gener…
Black Holes Inside and Out 2024: visions for the future of black hole physics
Niayesh Afshordi, Abhay Ashtekar, Enrico Barausse +27
The gravitational physics landscape is evolving rapidly, driven by our ability to study strong-field regions, in particular black holes. Black Holes Inside and Out gathered world e…
Black hole horizons must be veiled by photon spheres
Raúl Carballo-Rubio, Astrid Eichhorn
Horizons and bound photon orbits are defining features of black holes that translate into key features of black hole images. We present a purely geometric proof that spherically sy…
Fundamental Physics Opportunities with the Next-Generation Event Horizon Telescope
Dimitry Ayzenberg, Lindy Blackburn, Richard Brito +45
The Event Horizon Telescope (EHT) Collaboration recently published the first images of the supermassive black holes in the cores of the Messier 87 and Milky Way galaxies. These obs…
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…
