Thématique : Cosmologie observationnelle
The various observations of the Universe have been indicating for twenty years now that the expansion of the Universe is accelerating. The standard model of cosmology, known as the CDM model, describes the Universe as composed of 27% dark matter and 68% dark energy. Understanding the nature of these two energy components remains one of the greatest challenges in contemporary physics.
The future Euclid space mission is dedicated to the study of dark energy and dark matter in the Universe and to test gravity on cosmological scales. Euclid was selected by the European Space Agency (ESA) in 2011 and has been launched 1st July, 2023 to probe the Universe over a 6 year-period. These data will revolutionize our ability to map the Universe and better understand the nature of dark energy or put Einstein's General Relativity (GR) in default.
Two instruments are embarked on board Euclid, the Near Infrared Spectrometer and Photometer (NISP) and the visible imager (VIS). The spectroscopic survey with the NISP instrument will target 40 millions of galaxies in the redshift range 0.9 < z < 1.8, while the photometric survey will get the image and photometric redshift of two billions of galaxies covering the redshift range 0 < z < 2.5.
The subject of the thesis is to measure the galaxy clustering from the Euclid photometric and spectroscopic catalogs, and studied combined analysis, including 3x2pt analysis.
