An international team of scientists, with participation by researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) have found a barred spiral galaxy, similar to the Milky Way, in the early universe, when it was only 15% as old as it is now. The galaxy, ceers-2112, is the most distant barred spiral observed, and its existence poses a challege to the current model of formation and evolution of galaxies. The discovery, made with the James Webb Space Telescope (JWST) is published in the journal Nature. In astrophysics studying the structure of galaxies

Researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), publish today in the journal Astronomy & Astrophysics the first results of a detailed study of nearly a thousand blue supergiants in the Milky Way. This is the biggest sample of stars of this type which has been studied until now. The study has used over 15 years of high quality observations taken mainly with the NOT and Mercator telescopes at the Roque de los Muchachos Observatory in La Palma. The analysis of these data will allow researchers to improve their knowledge of the evolution of

An international research team, led from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) together with a group of Italian universities, has confirmed a new method for finding protoclusters of galaxies, the largest structures in the early universe. These progenitors of present-day clusters of galaxies played an essential role in the evolution of the universe, but are not easy to find. This study shows that a specific type of galaxies, those which emit radiation at submillimetre wavelengths, are very good indicators of the presence of distant protoclusters
