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.

Planetary Systems

The research interests of the Group of Planetary Systems focus on the origin and dynamic evolution of planets and small bodies around the Sun and other stars. Since the discovery of the first extrasolar planet in 1995 by Michel Mayor and Didier Queloz, we have witnessed a true revolution in planetary astronomy with several thousand of new systems detected so far. While some of their features are similar to our Solar system, others show marked differences, including planetary bodies in cometary and/or retrograde orbits, hot Jupiters and planets in multiple star systems. This enormous and growing diversity points towards planetary formation processes which may be much more complex than imagined a few years ago.

Our work is developed in unison with staff from the Astronomical Observatory of the UNC. Current research topics include:

  • Formation and orbital evolution of planets in binary star systems.
  • Models of tidal interaction and its application to planets and satellites.
  • Secular and resonant evolution of multiple planetary systems.
  • Resonant dynamics of satellites around gas giants.
  • Study of coorbital configurations around planets or stars.
  • Study of coorbital configurations around planets or stars.

In collaboration with colleagues from FaMAF, FCEFyN and researchers from other universities, we have recently undertaken studies on the dynamics of artificial satellites in LEO and MEO regions, searching for optimal de-orbiting mechanisms with minimum fuel consumption. We aim to develop dynamical algorithms that may help design future space missions complying with environmental and sustainability constraints.
