Numerical simulations are now a well established theoretical tool to study the many facets of galaxy formation. Simulations are able to capture several properties of galaxies by combining high resolution in galaxies to capture the multiphase inter-stellar medium together with direct modeling of their anisotropic large-scale flows, including cosmic inflows and large-scale galactic outflows leading to large circulations of gas in the circum-galactic medium. Nonetheless, the theory is far from perfect, and many of its successes heavily rely on a class of unresolved physics modeled with subgrid approaches. High-resolution observations by JWST, and upcoming full-sky surveys such as Euclid or LSST provide the opportunity to challenge and test the robustness of numerical models of galaxy formation in uncharted territories. This includes, but is not limited to, tests of: 

• the morphology of galaxies at the cosmic noon; 
• the role of mergers in shaping galaxy properties;
• the nature of early galaxies;
• the respective importance of stellar feedback and active galactic nuclei and their synergies; 
• the properties of dust in galaxies; 
• the nature and impact of the circum-galactic medium; 
• the exact role of cosmic ray feedback in galaxies; 
• the performance at high redshift of models calibrated at low redshift;
• the importance of anisotropic large-scale structures on galaxies; 
• the effect of baryons processes compared to (non-standard) dark matter, dark energy or modified gravity at halo and galaxy scales. 

This conference will be the opportunity to gather experts in the field of numerical galaxy simulations, discuss the advances of such models, their shortcomings, and the routes the community should take to make significant progress in our theoretical understanding of galaxies in light of current and new observations.
