Slowly rotating charged BTZ black hole solutions in Palatini Chern-Simons gravity
Flavio Bombacigno, Gonzalo J. Olmo, Emanuele Orazi +1
We consider a metric-affine formulation of Chern-Simons modified gravity in 2 + 1 dimensions. The theory is built requiring projective invariance, and the structure of the equation…
Dynamical system analysis of the cosmological phases in Palatini -essence gravity
Fabio Moretti, Flavio Bombacigno
We formulate a generalized -essence model in the presence of a Palatini gravitational sector. In the corresponding biscalar-tensor theory, we discuss the distin…
Gravitational waves in Palatini gravity for a non-minimal geometry-matter coupling
Flavio Bombacigno, Fabio Moretti, Gonzalo J. Olmo
We discuss the propagation of gravitational waves over a non-Riemannian spacetime, when a non-minimal coupling between the geometry and matter is considered in the form of contract…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Inflation in non-local hybrid metric-Palatini gravity
Flavio Bombacigno, Mariaveronica De Angelis, Carsten van de Bruck +1
Within the framework of hybrid metric-Palatini gravity, we incorporate non-localities introduced via the inverse of the d'Alembert operators acting on the scalar curvature. We anal…
Echoes from bounded universes
Renan B. Magalhães, Andreu Masó-Ferrando, Flavio Bombacigno +2
We construct a general class of modified Ellis wormholes, where one asymptotic Minkowski region is replaced by a bounded 2-sphere core, characterized by asymptotic finite areal rad…
