The Hubble and James Webb Space Telescopes, with their outstanding depth and spatial resolution, are opening up the possibility of studying the edges of disk galaxies over a significant cosmic time interval. This allows us to study in detail the evolution of galaxy edges over the past 8 Gyr. The edge of galaxies, understood here as the farthest

Ultra-diffuse galaxies (UDGs) are attractive candidates to probe cosmological models and test theories of galaxy formation at low masses; however, they are difficult to detect because of their low surface brightness. In the Local Group a handful of UDGs have been found to date, most of which are satellites of the Milky Way and M31, and only two are

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
