Euclid Spectroscopic Image Simulations and Reconstruction

Parallel Talk presented at the XX International Workshop on Neutrino Telescopes - Venice 23-27 October 2023 Abstract: Euclid is a European Space Agency (ESA) mission, designed to investigate the nature of Dark Energy and Dark Matter. It will measure the positions, shapes, andcolors for billions of galaxies, and also redshift for a subset of tens of millions of those galaxies to map the matter distribution with unprecedented accuracy. Thesatellite launch took place in July 2023, and the data taking will last for six years covering one-third of the entire sky. To attain the desired level of precision in parameter estimation, meticulous management of systematic effects is required. These effects have both…
