Una larga historia de alineamientoEl laboratorio natural más cercano de plasma: El Sol

A long alignment history

Cinthia Ragone-Figueroa, a researcher at the Instituto de Astronomía Teórica y Experimental (IATE), together with an international team, developed computational simulations that made it possible to verify that the galaxy clusters and their central galaxy have remained aligned for more than 8 thousand million years.

The closest natural plasma laboratory: The Sun

Abril Sahade, doctoral fellow at Instituto de Astronomía Teórica y Experimental (IATE), Mariana Cécere, a researcher at the same institute and Gustavo Krause of Instituto de Estudios Avanzados en Ingeniería y Tecnología (IDIT), published an article in which they analyze, starting from computational simulations, how material ejected from the Sun is deflected due to the presence of certain structures in the corona.

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.
