Photon spheres in dynamical space-times
David DÃaz-Guerra, Ãngel Rincón, Diego Rubiera-Garcia
The characterization of the photon region -- i.e. the region of space-time filled with unstable bound null geodesics -- is critical to understand the behavior of radiation near a c…
The gravitational wave-black hole imaging correspondence for modified black holes
David DÃaz-Guerra, David Díaz-Guerra, Ãngel Rincón +3
Black holes (BHs) can be studied via fundamentally different observational channels that probe complementary aspects of their physics. While BH imaging provides access to the quasi…
Probing Cosmic Expansion and Early Universe with Einstein Telescope
Angelo Ricciardone, Mairi Sakellariadou, Archisman Ghosh +52
Over the next two decades, gravitational-wave (GW) observations are expected to evolve from a discovery-driven endeavour into a precision tool for astrophysics, cosmology, and fund…
White Paper and Roadmap for Quantum Gravity Phenomenology in the Multi-Messenger Era
R. Alves Batista, G. Amelino-Camelia, D. Boncioli +101
The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put…
