Euclid preparation. The shape of halo profiles in CDM and non-standard cosmologies
Euclid Collaboration, L. Pizzuti, G. Y. Ferron +304
We study the shape of three-dimensional and projected dark-matter halo profiles extracted from cosmological -body simulations in CDM and non-standard cosmologies, using the \…
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…
A barotropic alternative to Early Dark Energy for alleviating the tension
Youri Carloni, Orlando Luongo
We propose a cosmological scenario in which, beyond matter and radiation, an additional barotropic fluid with positive equation of state contributes to the cosmic energy budg…
Mapping the redshift drift at various redshifts through cosmography
Anna Chiara Alfano, Orlando Luongo
The redshift drift provides a kinematic test of the cosmic expansion history through the slow time variation of the redshift of comoving sources. Motivated by the expected Sandage-…
