    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

    The European Solar Telescope project under review by an international team of experts
    The IACTEC headquarters has recently hosted the meeting between the engineering team behind the future European Solar Telescope and an international panel composed of some of the world's leading experts in the development of large telescopes and solar observation instrumentation. It is common for major scientific projects to undergo this type of scrutiny during their development as a way to independently verify their quality and viability. The evaluation process began over a month ago with the submission of all the design documentation to the reviewers. In this case, the evaluation focused

    The IAC is participating in the first European planetary defence mission
    Researchers Julia de León and Javier Licandro of the Instituto de Astrofísica de Canarias (IAC) are participating in the Hera mission of the European Space Agency (ESA) , successfully launched from Cape Canaveral, Florida (USA) on 7th October at 14:52 UTC. This is the first European mission for planetary defence which together with NASA’s DART (Double Asteroid redirection Test) will study the effects of a technique for diverting asteroids called “ kinetic impactor”. The DART probe crashed into the smaller ( Dimorphos) of the two asteroids which form the binary system Didymos, on September

    The light from quasars, a key to the measurement of the expansion of the distant universe
    The Instituto de Astrofísica de Canarias (IAC) in collaboration with the University of Geneva (Switzerland), the University of Osaka (Japan), and the University of Zhejiang (China) has made a key contribution to a more precise measurement of the expansion of the Universe. This is because they have made an improvement in the precision of the calculation of the scale of the universe in its early stages using the analisis of the distribution of gas in intergalactic space, measurements which reach back to epochs between 10,000 and 12,000 million years ago. This result comes from the análisis of

    Valentín Martínez Pillet y Antonia Varela inauguran la XXV edición de la Canary Islands Winter School of Astrophysics
    El director del Instituto de Astrofísica de Canarias (IAC), Valentín Martínez Pillet; y la directora del Museo de la Ciencia y el Cosmos, Antonia Varela, inauguraron esta mañana la XXV Canary Islands Winter School of Astrophysics. Esta tradicional escuela organizada por el IAC tiene lugar hasta el próximo 17 de octubre y acoge a 60 estudiantes de máster, doctorado y postdoctorado de trece países distintos que se encontrarán en Tenerife para recibir una visión completa y exhaustiva sobre la evolución de las galaxias. Valentín Martínez Pillet dio la bienvenida al estudiantado y expuso que esta

    The Metal-Poor Edge of the Milky Way’s Thin Disk
    The formation and evolution of the disk of our Galaxy, the Milky Way, remains an enigma in astronomy. In particular, the relationship between the thick disk and the thin disk —two key components of the Milky Way— is still unclear. Understanding the chemical and dynamical properties of the stars within these disks is crucial, especially in the parameter spaces where their characteristics overlap, such the metallicity regime around [Fe/H] ~ -0.7, which marks the metal-poor end of the thin disk, higher than that of the thick disk. This is often interpreted as an indication that the thin disk
