  • 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

    The Rubin Observatory begins its exploration of the sky with the support of the IAC and Grantecan
    The Vera C. Rubin Observatory, located in Chile, today released its first images of the universe, known in astronomy as an instrument's “first light”. This event marks the beginning of a project that will revolutionise our understanding of the universe over the next decade. Jointly funded by the US National Science Foundation (NSF) and the US Department of Energy (DOE), the Instituto de Astrofísica de Canarias (IAC) is participating, as part of a consortium of Spanish institutions, in its scientific exploitation and contributing observation time from the Gran Telescopio Canarias (GTC or

    Constraints on the in situ and ex situ stellar masses in nearby galaxies obtained with artificial intelligence
    The hierarchical model of galaxy evolution suggests that mergers have a substantial impact on the intricate processes that drive stellar assembly within a galaxy. However, accurately measuring the contribution of accretion to a galaxy's total stellar mass and its balance with in situ star formation poses a persistent challenge, as it is neither directly observable nor easily inferred from observational properties. Using data from MaNGA, we present theory-motivated predictions for the fraction of stellar mass originating from mergers in a statistically significant sample of nearby galaxies
