Coherent quantum geometry: de Sitter spacetime in different foliations
Tommaso Bambagiotti, Roberto Casadio, Andrea Giusti +1
In any theory of quantum gravity, an interesting question to address is to what extent known solutions of the Einstein field equations can be obtained as expectation values of metr…
Quantum dust cores of rotating black holes
Tommaso Bambagiotti, Roberto Casadio
Black holes are spacetimes that should describe the end state of the gravitational collapse of huge amounts of quantum matter. A quantum description of dust cores for black hole ge…
Quantum dust cores of black holes and their quasi-normal modes
Tommaso Bambagiotti, Luca Gallerani, Andrea Mentrelli +2
The quantum description of a gravitationally collapsed ball of dust proposed in Ref.~\cite{Casadio:2023ymt} is characterised by a linear effective Misner-Sharp-Hernandez mass funct…
Gravitational radiation reaction around a static black hole surrounded by a Dehnen type dark matter halo
Amjad Ashoorioon, Roberto Casadio, Khadije Jafarzade +2
We consider the motion of a particle in the geometry of a Schwarzschild-like black hole embedded in a dark matter (DM) halo with Dehnen type density profile and calculate the orbit…
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…
Quantum gravitational corrections at third-order curvature, acoustic analog black holes and their quasinormal modes
R. Casadio, C. Noberto Souza, R. da Rocha
Quasinormal modes for bosonic (scalar, electromagnetic, and axial gravitational) and fermionic field perturbations, radiated from black holes that carry quantum gravitational corre…
