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
The European Solar Telescope (EST) project has taken a decisive step towards construction with the establishment of the Board of Governmental Representatives (BGR), marking the first formal commitment at the governmental level to this European flagship in solar research. Until now, EST has been driven by a scientific consortium of universities and research institutions across Europe. The creation of the BGR transforms EST into a collaboration among European nations, whose national governments lend political support to the project and to the creation of a future European Solar Telescope
El proyecto educativo “CosmoLab: del aula al Sistema Solar”, desarrollado por el Instituto de Astrofísica de Canarias (IAC) y financiado principalmente por el Cabildo de Tenerife, anuncia la apertura de matrícula del nuevo curso “CosmoViaje 2.0: lo que sabemos e ignoramos del Universo” en colaboración con la Consejería de Educación del Gobierno de Canarias. Esta iniciativa busca acercar la astronomía a toda la comunidad educativa de Tenerife y fomentar el conocimiento y disfrute de los excepcionales cielos y observatorios de Canarias. CosmoLab persigue promover la cultura científica en el
