Description
SNe Ia are at the center of the actual tensions on H0 and w, parameters characterising the expansion of the Universe. Controlling surveys cross-calibration, selection functions and SNe Ia variability is important to avoid systematic biases in cosmological inference from SNe Ia. Realistic simulations are essential to address these systematics, but existing tools remain limited in their ability to capture the full complexity of SNe Ia populations and survey effects. I will introduce the context of my PhD by presenting the skysurvey framework, a simulation code made to simulate transients, like SNe Ia, as observed by any survey. I'll compare its predictions with the DR2 from the ZTF survey, and dicuss the future developments of this code so that we can simulate selection effects, SNe Ia population properties and their correlations with host-galaxy environments. This kind of realistic simulations can, in turn, be used to assess the accuracy of existing inference model.
