DESCRIPTION:Cosmological hydrodynamics simulations are a powerful tool in 
 the study of the formation and evolution of galaxies. To calibrate these s
 imulations and make quantitative predictions\, an apples-to-apples compari
 son to observational data is required.This is not trivial: hydrodynamics s
 imulations generate intrinsic properties such as stellar masses and SFRs\,
  which are not directly comparable to the measured properties of observed 
 galaxies. We have developed the forward modelling tool SKIRT to generate r
 ealistic synthetic images\, SEDs and spectra for galaxies from cosmologica
 l hydrodynamics simulations.The mock observations account for the differen
 t stellar populations\, the disturbing effects of the dusty ISM\, and the 
 3D geometry of galaxies\, and they can immediately be compared to observat
 ional data. I will present the latest results on the comparison of synthet
 ic data from different cosmological simulations (EAGLE\, TNG\, Auriga\, AR
 TEMIS…) to observational data from UV to mm wavelengths.Topics to be dis
 cussed include the cosmic spectral energy distribution\, multi-band lumino
 sity functions\, galaxy scaling relations\, and galaxy morphology indices 
 for different cosmological simulations. I will also briefly discuss other 
 possibilities and applications of the SKIRT code such as X-ray radiative t
 ransfer\, Lyman-alpha radiative transfer\, and non-LTE line radiative tran
 sfer.
