Study of oscillations in solar filaments

An international team of researchers from the Astrophysical Plasmas area of the Institute of Theoretical and Experimental Astronomy (IATE), based on computational simulations, analyzed and modelled how large solar prominences are affected by waves from the solar corona.

Explaining the origin of a type of galaxy

The breakthrough published in the prestigious journal Nature Astronomy was achieved by an international team of scientists led by José Benavides and Mario Abadi, from the National University of Córdoba (UNC) and CONICET, and Laura Sales, from the University of California, Riverside.

PISCIS: a citizen science tool for analysing astronomical images

A team from Instituto de Astronomía Teórica y Experimental (IATE), led by Vanessa Daza, Germán Alfaro and José Benavides, developed an interactive platform in which experts and non-experts can collaborate in the processing of astronomical data.

Large Scale Structure of the Universe

Large-scale_structure_formationThe large-scale structure of the Universe is the field of cosmology that studies the distribution of the matter in the Universe on the largest scales. This field has grown remarkably since the '80s, with the development of three-dimensional maps of galaxies in several bands of the electromagnetic spectrum, and with the observation of the Cosmic Microwave Background (CMB). The increasing flow of information generated by observations has allowed to obtain reliable characterization of the content of the universe comprising 74% of vacuum or dark energy, 26% dark matter and 4% ordinary baryonic matter, as well as its distribution. The distribution of the structures seems to follow a hierarchical model where the upper level is dominated by a network of clusters and filaments. On top of that, the universe appears to be isotropic and homogeneous in accordance with the cosmological principle. From the analysis of catalogs and the development of numerical simulations, the distribution is characterized through the implementation of different statistics that allow the study of the spatial distribution as well as the dynamics by means of the velocity field of the matter distribution.
