Description de la mission
The Euclid satellite, to be launched in 2022, will provide unique insights on the nature of the accelerated expansion of the Universe. The immense power of Euclid stems from a unique survey which will measure the positions and shapes of over a billion galaxies. These shape measurements, made on unique high-resolution wide-field images, will probe the underlying distribution of dark matter. Coupled with distance measurements they will enable a uniquely discriminating probe of our cosmological model.
In order to understand and quantify all sources of systematic errors in the Euclid ground segment processing and to understand what questions Euclid can answer it is essential to have realistic simulated images. To be useful, these simulations must cover a sufficiently large area and reach the highest possible redshifts. However, current input simulated catalogues for the Euclid main survey are currently missing higher-redshift objects; for this reason they do not provide a realistic picture of the distant Universe. For the Euclid deep fields, which have 40 times the depth of the normal Euclid survey, this is clearly insufficient. Better, deeper input catalogues are therefore necessary.
The Horizon Project has created a highly realistic hydrodynamical simulation of the Universe, Horizon-AGN, which features a realistic population of faint galaxies reaching out to high redshifts.
The objective of this internship is to use these input catalogues from the Horizon-AGN hydrodynamical simulation in combination with official Euclid instrument simulator to create and analyse a set of simulations of the Euclid deep fields.
These simulations will provide the first realistic look into the high-redshift Universe which will be unveiled by the Euclid deep fields. From these data we will determine the ability of Euclid and associated complementary datasets to detect distant galaxies, measure their shapes, and constrain the cosmological model.
This project will be carried out at the IAP (Institut d'Astrophysique de Paris, 98 bis Boulevard Arago, Paris 75014) under the direction of Henry J. McCracken and Clotilde Laigle.
