The Instituto de Astrofísica de Canarias (IAC) in collaboration with the University of Geneva (Switzerland), the University of Osaka (Japan), and the University of Zhejiang (China) has made a key contribution to a more precise measurement of the expansion of the Universe. This is because they have made an improvement in the precision of the calculation of the scale of the universe in its early stages using the analisis of the distribution of gas in intergalactic space, measurements which reach back to epochs between 10,000 and 12,000 million years ago. This result comes from the análisis of

The Instituto de Astrofísica de Canarias (IAC) is positioning itself as one of the main partners of the Government of the Canary Islands in the Canary Islands Aerospace Strategy, presented this Wednesday by President Fernando Clavijo. The goal is to position the archipelago as a key player in a rapidly growing sector, promoting innovation, technology transfer, and the creation of high value-added jobs.

The international CTAO LST Collaboration , in which the Instituto de Astrofísica de Canarias (IAC) plays a prominent role, released remarkable findings from observations of GRB 221009A—the brightest gamma-ray burst (GRB) ever recorded. The results were published by the renowned journal The Astrophysical Journal Letters (ApJ Letters) . The publication presents in-depth observations conducted in 2022 with the Large-Sized Telescope (LST ) prototype, the LST-1, during its commissioning phase at the Roque de los Muchachos Observatory (ORM) on the CTAO-North site in La Palma, Spain.
