A new study published in Astronomy & Astrophysics unveils a powerful way to determine the size of dark matter haloes—the massive, invisible structures that host galaxies—by simply measuring how large galaxies appear in deep astronomical images. Researchers Ignacio Trujillo and Claudio Dalla Vecchia, from the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL), demonstrate that galaxy size can serve as a precise proxy for halo size, offering measurements up to six times more accurate than previous methods. Using the cutting-edge EAGLE cosmological simulations
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
An international scientific team, including members of the Instituto de Astrofísica de Canarias (IAC), has launched an ambitious program to map exoplanets located around the Neptunian Desert —a region around stars where planets the size of Neptune are very rare— in order to better understand the mechanisms of planetary system evolution and formation. This scientific expedition has delivered its first results with the observation of the TOI-421 planetary system. Analysis of this system reveals a surprisingly inclined orbital architecture, offering new insights into the chaotic history of
