Euclid preparation. Testing analytic models of galaxy intrinsic alignments in the Euclid Flagship simulation

The episode discusses a paper testing analytic models of galaxy intrinsic alignments in a Euclid Flagship simulation. Researchers validated models like NLA and TATT, finding they accurately describe alignment down to six–seven h-one Mpc scales. Key findings include the need for luminosity dependence over simple power laws at higher redshifts, suggesting linking IA to halo mass evolution is more physically motivated.
