The advent of JWST has opened many new windows on galaxy evolution, unveiling new populations and detecting and characterizing galaxies up to very high redshifts. One of the key factors that can influence the evolution of galaxies is their surrounding and JWST is giving us new insights on the properties of galaxies in high density regions. Making using of the data of the GLASS-ERS survey (PI Treu) and its numerous follow ups, I’ll present new exiting results on this topic, including the discovery of filamentary structures at z=12, the detection and characterization of lensed protoclusters at  z=5-7, and the characterization of a new population of galaxies at z=0.3 characterized by extremely red F200W-F444W colors, most likely linked to environmental effects. 

Brief CV of Dr. Benedetta Vulcani:

She obtained my Phd at the University of Padova in 2012, with a joint project between the University and the Padova Observatory. Then she had several working experiences across the world (Carnegie Mellon Qatar, IPMU-University of Tokyo, University of Melbourne) before obtaining a permanent position at INAF-OAPD in 2016. The main focus on her research is characterizing the role of environment in shaping galaxy properties, both at low and high redshfits, using both integrated and spatially resolved quantities.
