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.

Recently, the exploitation of spectropolarimetric data has allowed to improve our knowledge of the dynamical and magnetic response of the photospheric and chromospheric layers to the rapid release of energy occurring during solar flares. In this framework, we have used high-resolution observations acquired on 22nd October 2014 during an X1.6

Symbiotic stars are strongly interacting binaries with long orbital periods, containing an evolved red giant and a white dwarf or a neutron star embedded in a circumbinary nebula. They constitute unique astrophysical laboratories important for understanding the binary evolution and diverse processes occurring also in many other types of
