A new year’s toast to Euclid: forecasts for galaxy and AGN selections and analysis using simulated data

Sala Jappelli (Osservatorio Astronomico di Padova)

The Euclid space mission, successfully launched last July, will cover around 15000 deg2 with two optical and near-infrared spectro-photometric instruments, and is expected to detect billions of galaxies and around ten millions of active galactic nuclei (AGN). This unique data set will make a considerable impact on our understanding of galaxy evolution in general, and AGN in particular. In order to understand Euclid capabilities and develop new analysis tools that can handle its large amount of data, in the last years we have developed a set of mock observations, derived either from ancillary dataset or from our novel phenomenological simulation SPRITZ (spectro-photometric realisations of infrared-selected targets at all-z). In this talk I will give a brief overview of these tools and I will present predictions for the selection of passive galaxies and active galactic nuclei, and for the derivation of galaxy physical properties using machine learning algorithms.
