Revelan detalles de la evolución de las galaxias que se zambullen en los cúmulosDescubrimiento de una galaxia inesperadamente solitariaAgujeros negros con carga eléctrica como alternativa a la materia oscura

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.
