Cosmographic reconstruction to discriminate between modified gravity and dark energy

САЖЕТАК:

Cosmography is a model independent approach, useful to
discriminate among concurring cosmological scenarios. After reviewing
the main features and shortcomings of LCDM model, we propose a
cosmographic approach, based on some polynomial series like Pade’,
Chebyschev, etc. to investigate dark energy and modified gravity. The
main result is that series convergence seems a powerful tool to extend
the matching with the Hubble flow up to high redshift and then improve
the role of observers in Cosmology.
