  • Dark galaxies in the Local Group
    Press release
    Galaxies that don’t shine: simulations predict a hidden population in the nearby universe
    The Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna are leading an international study on dark galaxies. ULL PhD student Guacimara García Bethencourt, together with her thesis supervisors Arianna Di Cintio and Sébastien Comerón, both lecturers in the Department of Astrophysics at the ULL and researchers at the IAC, presents a pioneering study in Astronomy & Astrophysics on one of the most intriguing objects in modern astrophysics: dark galaxies, systems rich in gas and dark matter but incapable of forming stars, and therefore invisible to traditional telescopes

  • Milky Way-like galaxies from the BEARD project
    Press release
    The first results of the BEARD project explain the survival of our Galaxy
    The international BEARD project, led from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), has used data from several telescopes at the Roque de los Muchachos Observatory, and computer simulations to explain how galaxies similar to the Milky Way have managed to survive the most violent stages of the history of the Universe. The present model for the evolution of the universe predicts an epoch dominated by important mergers of galaxies some ten thousand million years ago. “It’s a case of violent interactions, in which it is foreseeable that weak structures

    Press release
    IAC y ULL led the identification of the longest orbital period exoplanets among those transiting young stars
    An international collaboration of astronomers led by the Universidad de La Laguna (ULL) and Instituto de Astrofísica de Canarias (IAC) has identified two intriguing, humongous but light planets orbit ing HD 114082. This star is only 15 million years old, this is, much younger than the Sun (4.6 billion years old) , spin s 15 times faster , has 28% more mass , and is about one thousand degrees hotter and almost four times more luminous. Its planets receive about 200 times more light and heat than Jupiter. The study, which involved separating the faint planetary signal from the stellar one

    Galaxy transformation across the cosmic web: The influence zone of filaments
    The Universe is not distributed uniformly. Galaxies are arranged in a gigantic cosmic web made of voids, filaments, and galaxy clusters. These filaments act as enormous “cosmic highways” through which matter and galaxies flow toward the densest regions of the Universe. Understanding how these structures influence galaxy evolution is one of the major goals of modern astrophysics. In this work, we analyzed hundreds of thousands of galaxies from the Sloan Digital Sky Survey (SDSS) to study how galaxy density changes around cosmic filaments in the nearby Universe. Our main goal was to determine
