El Instituto de Astrofísica de Canarias (IAC) ha celebrado, este jueves 24 de julio de 2025, el 40 aniversario de la inauguración oficial de su sede central y de sus dos observatorios. Un acto que ha estado centrado en destacar el trabajo de los cientos de personas que han contribuido a convertir el IAC en uno de los centros de excelencia investigadora y técnica más importantes del mundo. En el acto, el director fundador del IAC, Francisco Sánchez, ha tenido un papel fundamental pese a que sus problemas de salud no le hayan permitido participar en el mismo. El lema de este 40 aniversario ha
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 Vera C. Rubin Observatory, located in Chile, today released its first images of the universe, known in astronomy as an instrument's “first light”. This event marks the beginning of a project that will revolutionise our understanding of the universe over the next decade. Jointly funded by the US National Science Foundation (NSF) and the US Department of Energy (DOE), the Instituto de Astrofísica de Canarias (IAC) is participating, as part of a consortium of Spanish institutions, in its scientific exploitation and contributing observation time from the Gran Telescopio Canarias (GTC or
