Linear perturbation theory and structure formation in a Brans-Dicke theory of gravity without dark matter
Lorenzo Gervani, Antonaldo Diaferio, Francesco Pace +1
We investigate the formation of the large-scale cosmic structure in a scalar-tensor theory of gravity belonging to the class of the Brans--Dicke theories. The universe contains bar…

Kinetic coupled tachyon: A dynamical system analysis
Francesco Pace, Alberto Rozas-Fernández, Ãzgen Tunç Türker
We present and examine a kinetically coupled tachyon dark energy model, where a tachyon scalar field interacts with the matter sector. More specifically, we deduce this cosmologica…

Linear perturbations in Horndeski theories with spatial curvature
Serena Gambino, Francesco Pace
We analyse the implications of the presence of spatial curvature in modified gravity models. As it is well known, the current standard cosmological model, the CDM, is assumed t…
