The gas-phase metallicity distribution within galaxies records critical information about galactic evolution. In this work, we investigate how active galactic nuclei (AGNs) influence this distribution by measuring the two-point correlation functions of gas-phase metallicity in 95 non-AGN and 37 AGN-host galaxies from the Calar Alto Legacy Integral

Some ultra diffuse galaxies (UDGs) reveal many more globular clusters (GCs) than classical dwarf galaxies of the same stellar mass. These UDGs, with a mass in their GC system ( $M_{\rm GC}$) approaching 10 per cent of their host galaxy stellar mass ( $M_{\ast }$), are also inferred to have high halo mass to stellar mass ratios ( $M_{\rm halo}/M_{

Cosmological analyses using galaxy clusters in optical/near-infrared photometric surveys require robust characterization of their galaxy content. Precisely determining which galaxies belong to a cluster is crucial. In this paper, we present the COlor Probabilistic Assignment of Clusters And BAyesiaNAnalysis (Copacabana) algorithm. Copacabana
