A study conducted with the new WEAVE , installed on the Telescopio William Herschel (WHT) at the Observatorio del Roque de los Muchachos (La Palma), and in whose construction the Instituto de Astrofísica de Canarias (IAC) participated, has revealed clear signs of shock interaction in the Type II supernova SN 2023ixf. Almost a year after the explosion, the data obtained with WEAVE reveal complex emission features that provide new clues about the processes shaping the final stages of massive star evolution. SN 2023ixf, located in the nearby galaxy M101, is the closest Type II supernova

The Roque de los Muchachos Observatory (ORM) of the Instituto de Astrofísica de Canarias (IAC), located on La Palma, has reached another important milestone with the installation of the camera of the LST-4, one of the four Large-Sized Telescopes (LST), which will be part of the Cherenkov Telescope Array Observatory (CTAO), currently under construction. The installation of the camera represents the completion of the telescope assembly and marks its transition to the commissioning phase. After a thorough performance evaluation at the IACTEC building, the IAC's technological and business
