El ciclo de charlas divulgativas Del Cielo a la Tesis, impulsado por el estudiantado predoctoral del Instituto de Astrofísica de Canarias (IAC) y la Universidad de La Laguna (ULL) para acercar la investigación en astrofísica a la ciudadanía, celebrará una nueva sesión el próximo 22 de enero de 2026 a las 16:30 horas en el Museo de la Ciencia y el Cosmos, del Organismo Autónomo de Museos y Centros del Cabildo de Tenerife. En esta ocasión, la cita propone un viaje al pasado de nuestra galaxia a través de dos ponencias que abordan cómo se forman y evolucionan los cúmulos de estrellas y cómo lasAdvertised on -
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 adaptiveAdvertised on -
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.
