Top-Hat Spherical Collapse with Clustering Dark Energy. I. Radius Evolution and Critical Contrast Density
D. Herrera, I. Waga, S. E. Jorás
Understanding the influence of dark energy on the formation of structures is currently a major challenge in Cosmology, since it can distinguish otherwise degenerated viable models.…

Calculation of the critical overdensity in the spherical-collapse approximation
D. Herrera, I. Waga, S. E. Jorás
Critical overdensity is a key concept in estimating the number count of halos for different redshift and halo-mass bins, and therefore, it is a powerful tool to compare cosmo…

Chaos in a closed Friedmann-Robertson-Walker universe: An imaginary approach
S. E. Jorás, T. J. Stuchi
In this work we study the existence of mechanisms of transition to global chaos in a closed Friedmann-Robertson-Walker universe with a massive conformally coupled scalar field. We…
