Redshift dependence and dipolar velocity corrections in cosmographic reconstructions through Type Ia supernova samples
Anna Chiara Alfano, Youri Carloni, Orlando Luongo +1
We perform a cosmographic analysis of Type Ia supernovae using the Pantheon+\&SH0ES, DES-SNY5 and Union3 compilations. We consider different redshift intervals, analyzed through a…
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…
Euclid preparation. Modelling spectroscopic clustering on mildly nonlinear scales in beyond-CDM models
Euclid Collaboration, B. Bose, P. Carrilho +229
We investigate the approximations needed to efficiently predict the large-scale clustering of matter and dark matter halos in beyond-CDM scenarios. We examine the normal branch…
