Effective dynamics of scalar cosmological perturbations from quantum gravity

Luca Marchetti, Daniele Oriti

We derive an effective dynamics for scalar cosmological perturbations from quantum gravity, in the framework of group field theory (GFT) condensate cosmology. The emergent spacetim…

Population inference of spin-induced quadrupole moments as a probe for non-black hole compact binaries

Muhammed Saleem, N. V. Krishnendu, Abhirup Ghosh +4

Gravitational-wave (GW) measurements of physical effects such as spin-induced quadrupole moments can distinguish binaries consisting of black holes from non-black hole binaries. Wh…

Phase transitions in tensorial group field theories: Landau-Ginzburg analysis of models with both local and non-local degrees of freedom

Luca Marchetti, Daniele Oriti, Andreas G. A. Pithis +1

In the tensorial group field theory approach to quantum gravity, the theory is based on discrete building blocks and continuum spacetime is expected to emerge from their collective…

Effective cosmology from one-body operators in group field theory

Steffen Gielen, Luca Marchetti, Daniele Oriti +1

We propose a new method for obtaining an effective Friedmann-Lemaître-Robertson-Walker (FLRW) cosmology from the quantum gravity dynamics of group field theory (GFT), based on the…

Constraints on Kerr-Newman black holes from merger-ringdown gravitational-wave observations

Gregorio Carullo, Danny Laghi, Nathan K. Johnson-McDaniel +4

We construct a template to model the post-merger phase of a binary black hole coalescence in the presence of a remnant $U (1)$ charge. We include the quasi-normal modes typically do…
