Explore the formation of thin and thick discs in galaxies through this conference talk from the "Co-evolution of the Cosmic Web and Galaxies across Cosmic Time" conference. Delve into the emergence and evolution of galactic disks, comparing observations from the New Horizon simulation with other galaxies and synthetic disks. Examine topics such as disk heating, alpha enhancement, bimodality, circularity, and spatial classification. Gain insights into the complex processes shaping galaxy structure and evolution within the cosmic web framework, and understand their implications for cosmology and structure formation.
