Cosmological Signatures of Curvature-Coupled Dark Energy
Abdolali Banihashemi, Farbod Hassani, Alessandro Casalino +2
We study a curvature-coupled dark energy model that can modify cosmological evolution both before recombination and during the late-time accelerated era. The model belongs to the c…
Local solutions of General Relativity in the presence of the Trace Anomaly
Marco Calzá, Alessandro Casalino, Lorenzo Sebastiani
Local solutions are a vivid and long-living topic in gravitational physics. We consider exact static pseudo-spherically symmetric solutions of semi-classical Einstein's equations i…
Bounce Models within Teleparallel modified gravity
Alessandro Casalino, Bruno Sanna, Lorenzo Sebastiani +1
In this paper, working in a Friedman-Lemaitre-Robertson-Walker (FLRW), first, in the flat case, we recover the generalized Friedman equation of Quantum Loop cosmology, and therefor…
Perturbations in Regularized Lovelock Gravity
Alessandro Casalino, Lorenzo Sebastiani
In this paper we study the perturbation theory of the recently proposed Regularized Lovelock Gravity, on the curved FLRW space-time. We provide the first order perturbation equatio…
A note on non singular Einstein-Aether cosmologies
Alessandro Casalino, Lorenzo Sebastiani, Sergio Zerbini
An effective Lagrangian approach based on an extended Einstein-Aether (EA) model is presented and formulated in a generic non flat Fridman-Lemaitre-Robertson-Walker (FLRW) space-ti…
Regularized Lovelock gravity
Alessandro Casalino, Aimeric Colleaux, Massimiliano Rinaldi +1
A four-dimensional regularization of Lovelock-Lanczos gravity up to an arbitrary curvature order is considered. We show that Lovelock-Lanczos terms can provide a non-trivial contri…
Higher derivative and mimetic models on non flat FLRW space-times
Alessandro Casalino, Lorenzo Sebastiani, Luciano Vanzo +1
An effective Lagrangian approach, partly inspired by Quantum Loop Cosmology (QLC), is presented and formulated in a non flat FLRW space-times, making use of modified gravitational…
Kinematic reconstructions of extended theories of gravity at small and intermediate redshifts
Marco Calzà, Alessandro Casalino, Orlando Luongo +1
In the last few decades, extensions of General Relativity have reached always more attention especially in view of possible breakdowns of the standard CDM paradigm at intermedia…
Alive and well: mimetic gravity and a higher-order extension in light of GW170817
Alessandro Casalino, Massimiliano Rinaldi, Lorenzo Sebastiani +1
The near-simultaneous multi-messenger detection of the gravitational wave (GW) event GW170817 and its optical counterpart, the short -ray burst GRB170817A, implies that deviatio…
Testing Horndeski gravity as dark matter with $\texttt{hi_class}$
Alessandro Casalino, Massimiliano Rinaldi
We consider a model of dark matter fluid based on a sector of Horndeski gravity. The model is very successful, at the background level, in reproducing the evolution of the Universe…
Mimicking dark matter and dark energy in a mimetic model compatible with GW170817
Alessandro Casalino, Massimiliano Rinaldi, Lorenzo Sebastiani +1
The recent observation of the the gravitational wave event GW170817 and of its electromagnetic counterpart GRB170817A, from a binary neutron star merger, has established that the s…
