From 13 to 17 April 2026, the University of Groningen (The Netherlands) hosted the ExGal-Twin 2nd Radio Astronomy School and 2nd Project Meeting, key activities of the European project ExGal-Twin, coordinated by the Instituto de Astrofísica de Canarias (IAC). The event brought together researchers, students and technical staff from the IAC and the partner institutions: the Kapteyn Astronomical Institute (University of Groningen), the Institute for Computational Cosmology (Durham University), and the Observatoire Astronomique de Strasbourg (CNRS), reinforcing scientific collaboration and

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

During October, the Adaptive Optics System team at the Gran Telescopio Canarias (GTCAO) of the Instituto de Astrofísica de Canarias (IAC), in collaboration with the technical team at the Gran Telescopio Canarias (GTC or Grantecan), successfully completed the integration of the GRANCAIN instrument into the world's largest optical-infrared telescope. The installation was carried out at the GTCAO outlet on the telescope's Nasmyth B platform, a key step in initiating performance testing of the new adaptive optics system. This is the first scientific instrument to operate using the GTC's adaptive
