Explore the Energy Minimisation Principle and its connection to protohalo shapes and anisotropic infall in this 34-minute conference talk by Marcello Musso from the University of Salamanca. Delivered at the "Co-evolution of the Cosmic Web and Galaxies across Cosmic Time" conference at KITP, delve into topics such as energy peaks, halo mass function, shear-shape alignment, torques, and the relationship between protohaloes and equipotential surfaces. Gain insights into the cosmic web's role in galaxy formation and evolution, and its implications for cosmology and structure formation. Examine how this principle contributes to understanding the dynamics and morphology of galaxies within the web's filamentary flow across cosmic time.
