    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

    The LST-1 at the Roque de los Muchachos Observatory provides new clues about gamma-ray bursts jets
    The international CTAO LST Collaboration , in which the Instituto de Astrofísica de Canarias (IAC) plays a prominent role, released remarkable findings from observations of GRB 221009A—the brightest gamma-ray burst (GRB) ever recorded. The results were published by the renowned journal The Astrophysical Journal Letters (ApJ Letters) . The publication presents in-depth observations conducted in 2022 with the Large-Sized Telescope (LST ) prototype, the LST-1, during its commissioning phase at the Roque de los Muchachos Observatory (ORM) on the CTAO-North site in La Palma, Spain.

  • Rare pair of interacting dwarf galaxies observed by the CAVITY project
    Press release
    The IAC participates in the study of an unusual merger of two dwarf galaxies in a cosmic void environment
    An international team of researchers, including researchers from the IAC, have studied in detail a remarkable couple of dwarf galaxies “dancing with each other” inside an unpopulated area of the Universe. This uncommon pair of low-mass galaxies merging “in the middle of nowhere”, near the center of a cosmic void, offers a unique view of one-on-one interactions and of the evolution of galaxies located in very low density environments. Researchers from the Calar Alto Void Integral-field Treasury surveY (CAVITY) project, led by the University of Granada, have discovered a rare and ongoing
