  • Star Formation Image

    Astrobiology

    We carry out theoretical studies on planetary atmospheres, planetary habitability conditions, and remote detection of life on exoplanets. Additionally, we conduct experimental research on the physical and chemical characteristics of protoplanetary disks and meteorite components.

    Researchers: Antígona Segura

  • Star Formation Image

    Computational Astrophysics and Data Science

    We employ high-performance computing to simulate hydrodynamics, magnetohydrodynamics, and radiative transfer in astrophysical phenomenta. Additionally, we apply machine learning and statistical techniques to analyze large astronomical datasets, to understand their behaviour. Also, we develop numerical methods to solve complex astrophysical problems.

    Researchers: Fabio De Colle, Diego López-Cámara, Pablo Velázquez

  • Star Formation Image

    Cosmology and galaxies

    Our research explores the large-scale structure of the Universe, and the nature of dark matter and dark energy.

    Researchers: Verónica Lora, Marcelo Salgado

  • Star Formation Image

    Gravitation and general relativity

    We explore fundamental aspects of strong gravitational fields. In particular, we study the dynamics of compact objects such as neutron stars, black holes, boson stars, and Proca stars, among others.

    Researchers: Miguel Alcubierre, Néstor Ortiz, Hernando Quevedo, Marcelo Salgado

  • Star Formation Image

    High Energy Astrophysics

    Our research focuses on Gamma-Ray Bursts, Supernovae, Tidal Disruption Events, Fast Blue Optical Transients, and other high-energy transients, with an emphasis on using numerical simulations to investigate their complex dynamics. We study the behavior of relativistic jets, shock waves, and the resulting radiation emissions to understand the physical processes driving these events.

    Researchers: Fabio De Colle, Diego López-Cámara, Sarira Sahu

  • Star Formation Image

    Star Formation

    Research on star formation focuses on various astrophysical flows, particularly supernova remnants, turbulence in molecular clouds, and protostellar jets. These processes play a crucial role in shaping the interstellar medium and regulating star formation rates. Other studied flows include galactic-scale outflows, such as starburst-driven winds and mass redistribution in galaxies, which influence the long-term evolution of galactic structures. Additionally, researchers investigate photoionized regions and the interaction of exoplanets with stellar winds, providing insights into the conditions that shape planetary atmospheres and their potential habitability.

    Researchers: Alejandro Esquivel, Veronica Lora, Ary Rodríguez González, Juan Claudio Toledo Roy, Pablo Velázquez

  • Star Formation Image

    Stellar evolution

    Our research focuses on stellar evolution of binary systems, particularly the common envelope phase. Using numerical simulations, we study mass transfer, angular momentum dynamics, and their role in forming compact object binaries and producing high energy transitory phenomena.

    Researchers: Fabio De Colle, Diego López-Cámara


Students & Postdocs


Students interested in pursuing research in astrophysics can find a variety of thesis topics, both at undergraduate and graduate (master's and PhD) level. We are part of the Graduate Programs in Astrophysics. Some of us are also associated to the Graduate Programs in Earth Science and Physics at UNAM. If you are interested in one of our research topics (see the research section above) feel free to contact us directly.

Postdoctoral positions are available typically every year by an internal competition at UNAM or by using "Conahcyt" funds. Each postdoctoral researcher will have the opportunity to work closely with one of us. Please contact us directly to discuss potential applications.
