Scale-invariant alternatives to general relativity. III. The inflation--dark-energy connection
Santiago Casas, Georgios K. Karananas, Martin Pauly +1
We discuss the cosmological phenomenology of biscalar-tensor models displaying a maximally symmetric Einstein-frame kinetic sector and constructed on the basis of scale symmetry an…
The road ahead of Horndeski: cosmology of surviving scalar-tensor theories
Noemi Frusciante, Simone Peirone, Santiago Casas +1
In the context of the effective field theory of dark energy (EFT) we perform agnostic explorations of Horndeski gravity. We choose two parametrizations for the free EFT functions,…
Model-independent reconstruction of the linear anisotropic stress
Ana Marta Pinho, Santiago Casas, Luca Amendola
In this work, we use recent data on the Hubble expansion rate , the quantity from redshift space distortions and the statistic from clustering and lensing obs…
