    A student from the ULL and the IAC participates in the International Summer Student Program linked to the Vera C. Rubin Observatory
    Daniel Cano Morales, a physics student at the University of La Laguna (ULL) who is completing his final degree project (TFG) at the Instituto de Astrofísica de Canarias (IAC), has participated in the 2025 Summer Student Program organized by the LSST Discovery Alliance (LSST-DA) in Tucson (Arizona, USA). The meeting, held in parallel with the Rubin Community Workshop, brought together seventeen university students from LSST-DA member institutions around the world in July. The program offered participants a unique opportunity to present their research, interact with internationally renowned

    El IAC organiza un congreso internacional que conmemora el 30 aniversario del descubrimiento de las primeras enanas marrones
    El Hotel Jardín Tecina de La Gomera ha sido la sede del congreso internacional “Brown dwarfs keep their cool. 30 years of substellar science” , organizado por los investigadores del Instituto de Astrofísica de Canarias (IAC) Nicolas Lodieu y Victor J. S. Bejar, que ha reunido esta primera semana de septiembre a expertos de todo el mundo en el campo de los objetos subestelares. El encuentro conmemora el 30 aniversario de un descubrimiento histórico que marcó un antes y un después en la Astrofísica: la detección de las primeras enanas marrones. El acto inaugural contó con la presencia de

    The IAC wins the third ERC European Council 2025 grant with a project about the first stars in the Universe
    IAC researcher David Aguado has obtained a prestigious Starting Grant from the European Research Council (ERC), aimed at promoting promising young scientists. This is the third ERC grant -one of the most competitive and recognized of the Horizon Europe program- that the center has received so far this year, thus consolidating its international projection. These highly competitive grants provide up to €1.5 million over five years to support outstanding young scientists in establishing their own independent research groups and pursuing pioneering scientific ideas. Searching for the first stars

    A physically motivated galaxy size definition across different state-of-the-art hydrodynamical simulations
    Measuring galaxy sizes is essential for understanding how they were formed and evolved across time. However, traditional methods based on l ight concentration or isophotal densities often lack a clear physical meaning. A recent study from Trujillo+20 explores a more physically motivated definition: the radius R 1, where the stellar surface density falls to 1 solar masses per parsec square —roughly the threshold for gas to form stars in galaxies like the Milky Way. In this work, Arjona-Gálvez+25 uses over 1,000 galaxies from several state-of-the-art cosmological simulations (AURIGA, HESTIA

    A team with the participation of the IAC and the ULL discovers that massive stars prefer to live in pairs even in galaxies with low metallicity
    Massive stars in metal-poor galaxies often have close partners, just like the massive stars in our metal-rich Milky Way. This has been discovered by an international scientific team in which research staff from the Instituto de Aastrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) participate. They used the European Very Large Telescope in Chile to monitor the velocity of massive stars in the Small Magellanic Cloud. The research is published in Nature Astronomy . For the past twenty years, astronomers have known that many massive stars in the metal-rich Milky Way have a
