Title:	Science and instrumentation developments at IRSOL and contributions to the EST
Authors:	Renzo Ramelli and IRSOL staff
Abstract:	Istituto ricerche solari Aldo e Cele Daccò (IRSOL) carries out fundamental research in solar physics, with a focus on solar magnetism. The Institute’s mission is to understand solar magnetic phenomena to a detail that is needed for forecasting solar activity evolution and its effects on the space weather and terrestrial climate. This is achieved by combining the unique strengths of IRSOL in high-precision solar spectropolarimetry with advanced approaches in theoretical and numerical modelling, computational and data science, and magnetohydrodynamic simulations. IRSOL’s 45 cm telescope, the largest ground-based solar optical telescope in Switzerland, is equipped with the world-leading solar imaging polarimeter ZIMPOL. This unique observational facility has been recognized as an infrastructure of national and international importance. Since 2023, USI&IRSOL have been among the nine international cofounders of the EST Foundation Canarias, which aims at constructing the next-generation European Solar Telescope (EST). IRSOL aims to contribute to the EST with its expertise in high-precision polarimetric instrumentation and cutting-edge numerical data analysis tool.
