Περίληψη :
The evolution of galaxies is profoundly influenced by the environments they inhabit in the cosmic web. At the lowest end of the density spectrum, cosmic voids host galaxies that evolve in relative isolation, largely shielded from the dynamical processes typical of denser regions. These properties make voids exceptional laboratories for probing galaxy evolution in pristine conditions. The upcoming generation of wide-field surveys, led by the Euclid mission now entering its data-phase, will dramatically improve our ability to map the cosmic web, offering the depth and wide-area coverage required to characterise voids across cosmic time.
Conversely, groups and clusters provide a window into the transformative processes that operate in overdense environments. Understanding how these massive structures are assembled requires identifying their progenitors at high redshift and studying their environment. Hyper-luminous, heavily obscured quasars known as Hot Dust-Obscured Galaxies (Hot DOGs) have emerged as promising tracers of such early-time overdensities and protocluster regions.
By presenting my PhD work on both voids and high-redshift overdensities, this seminar will examine how galaxies evolve under the most extreme environmental conditions in the cosmic web and what these complementary regimes reveal about the co-evolution of galaxies and the large-scale structures that host them.
