Effects of dynamical friction on perturbations for evolving dark energy
Francesco Pace, Orlando Luongo, Antonino Del Popolo
We explore the impact of dynamical friction on scales where the linear growth factor and the spherical collapse model can be applied and show its influence on the evolution of pert…

Linear and nonlinear clusterings of Horndeski-inspired dark energy models with fast transition
Orlando Luongo, Francesco Pace, Sebastiano Tomasi
We analyze time-dependent dark energy equations of state through linear and nonlinear structure formation and their quintessence potentials, characterized by fast, recent transitio…
