A multiwavelength characterization of protocluster members in the ESO SHARKS survey

The main goal of this thesis is to characterize the physical properties of a sample of galaxy cluster members (provided by Lorenzon et al, in prep.), pre-selected from the Southern H-ATLAS Regions Ks-band Survey (SHARKS), a VISTA/ESO campaign. By cross matching SHARKS with public Dark Energy Survey (DES) data, I have created a multi-wavelength photometric catalog including G, I , R , Y, Z and K bands for each cluster member candidate. Using an SED fitting program (BAGPIPES) I have computed photometric redshifts, stellar masses and SFR for each single object in the parent catalog. In my Thesis I will present a statistical analysis of the cluster properties, with a particular focus on the redshift distribution of the sources in each cluster, divided by their color properties.
