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.

Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study using data from the Dark Energy Spectroscopic Instrument (DESI) has traced how this cosmic structure grew over the past 11 billion years, providing the most precise test to date of gravity at very large scales. DESI is an international collaboration of more than 900 researchers, included the Instituto de Astrofísica de Canarias (IAC), from over 70 institutions around the world and is managed by
