Details of the evolution of "backsplash" galaxies unravelled

A study led by a team from the Institute for Theoretical and Experimental Astronomy (IATE), using computer simulations, explains the transformation of galaxies that enter and leave a cluster.

Unexpectedly lonely galaxy discovered

An international team, including Carlos Donzelli, a researcher at the Instituto de Astronomía Teórica y Experimental (IATE) and the Observatorio Astronómico de Córdoba, made a finding that could challenge the timescales in which galaxies are expected to grow. These results were obtained using data from NASA’s Chandra X-ray Observatory and the Gemini International Observatory.

Black holes with electric charge as an alternative to dark matter

Un equipo internacional co-dirigido por Nelson Padilla, investigador del Instituto de Astronomía Teórica y Experimental (IATE), publicaron un artículo que vincula los agujeros negros, las cargas eléctricas y la materia oscura.

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.
