The European Solar Telescope (EST) will be part of the next generation of ground-based solar telescopes. With a primary mirror of 4.2 meters, it will be the largest solar telescope ever built in Europe offering a large collecting area and extremely sharp images, due to the Adaptive Optics (AO) system integrated within the optical path to compensate

According to dynamo theory, stars with convective envelopes efficiently generate surface magnetic fields, which manifest as magnetic activity in the form of starspots, faculae, and/or flares, when their rotation period is shorter than their convective turnover time. Most red giants, having undergone significant spin down while expanding, have slow

The GLACE (GaLAxy Cluster Evolution) survey represents a groundbreaking effort to explore the evolution of galaxies within galaxy clusters. Using data from the Gran Telescopio de Canarias (GTC), GLACE investigates emission line galaxies (ELGs) and active galactic nuclei (AGN) hosts across various redshifts. Recent observations within the ZwCl 0024
