Hybrid Models of Large-Scale Structure: Turning Your N-body Simulation into a Predictive Framework

Have you ever wondered what the best approach is to model the large-scale structure of the Universe? If your instinct is to pour every bit of astrophysical detail --star formation, galactic winds, dust collapse, black hole feedback-- into a simulation and then extract cosmological parameters from it... think again.
In this talk, I’ll explore why this brute-force strategy may not be the optimal path, and I’ll introduce an alternative: Hybrid Models. Built from N-body simulations and defined by the symmetries of structure formation physics, these models offer an alternative to Effective Field Theory. Curious to find out how --and why-- they work? Then don’t miss this talk!
