<i>Euclid</i> preparation Open
Future data provided by the Euclid mission will allow us to better understand the cosmic history of the Universe. A metric of its performance is the figure-of-merit (FoM) of dark energy, usually estimated with Fisher forecasts. The expecte…
Bootstrap Method with Fisher Formalism in Cosmology Open
The document presents the application of the Bootstrap method to Fisher matrices to analyze uncertainties in parameters estimations. It combines two Fisher matrices (like spectroscopic and photometric probes in EUCLID cosmological survey) …
Gravitation And the Universe from large Scale-Structures: The GAUSS mission concept Open
Today, thanks in particular to the results of the ESA Planck mission, the concordance cosmological model appears to be the most robust to describe the evolution and content of the Universe from its early to late times. It summarizes the ev…
Forecasting on next wide cosmological surveys of Stage IV : DESI - LSST - EUCLID Open
The international community involved in the study and understanding of the expansion of the Universe will soon benefit from the data collected by future major surveys that are the EUCLID missions as a space telescope and ground-based teles…
