Pixel simulations are essential in several phases of a project as they provide mock data that allows us to design, test and optimize the analysis of the images, prior to the real observations. They are also key to evaluate the performance of a survey and help to understand the causes of unknown systematics once the mission starts.
In this talk, I will explain the work I (with many others) have done in producing pixel image simulations for various cosmology surveys such as DES, DESI, PAU and Euclid. For the Dark Energy Survey Camera (DECam) and the Dark Energy Spectroscopy Instrument (DESI) were we are responsible for the auto-guiding system we simulated realistic detector images. Secondly, I will present the PAUCam-WHT pixel simulations, used to design the data reduction pipeline. And finally, I will give an overview of the Euclid science ground segment and explain the work at the Organization Unit of SIM, detailing all the end-to-end simulations we are currently delivering for the mission.
