Spherically symmetric elastic bodies in general relativity
Artur Alho, José Natário, Paolo Pani +1
The purpose of this review it to present a renewed perspective of the problem of self-gravitating elastic bodies under spherical symmetry. It is also a companion to the papers [Phy…
Scale invariant elastic stars in General Relativity
Artur Alho, José Natário, Paolo Pani +1
We present a model of relativistic elastic stars featuring scale invariance. This implies a linear mass-radius relation and the absence of a maximum mass. The most compact spherica…
Compactness bounds in General Relativity
Artur Alho, José Natário, Paolo Pani +1
A foundational theorem due to Buchdahl states that, within General Relativity (GR), the maximum compactness of a static, spherically symmetric, perfec…
Compact elastic objects in general relativity
Artur Alho, José Natário, Paolo Pani +1
We introduce a rigorous and general framework to study systematically self-gravitating elastic materials within general relativity, and apply it to investigate the existence and vi…
Testing the nature of dark compact objects with gravitational waves
Elisa Maggio, Paolo Pani, Guilherme Raposo
Within Einstein's theory of gravity, any compact object heavier than a few solar masses must be a black hole. Any observation showing otherwise would imply either new physics beyon…
Black-hole microstate spectroscopy: ringdown, quasinormal modes, and echoes
Taishi Ikeda, Massimo Bianchi, Dario Consoli +4
Deep conceptual problems associated with classical black holes can be addressed in string theory by the ``fuzzball'' paradigm, which provides a microscopic description of a black h…
