To measure cosmological parameters, the Euclid space telescope will use two main probes: gravitational lensing (Weak Gravitational Lensing) and galaxy distribution (Galaxy Clustering).
New statistical methods reveal the finest details of the Universe
A team led by University College London (UCL), in collaboration with the Astrophysics Department of CEA-Irfu, has significantly improved the analysis of dark matter maps in the Universe with new methods of data analysis.
The Near IR Spectrometer Photometer (NISP) is an infrared spectro-photometer that will equip the Euclid Space Telescope (launch planned for 2021) to better understand dark matter and dark energy.
In a review article in "Reports on Progress in Physics", Martin Kilbinger of Astrophysics Department - AIM Laboratory at CEA-IRFU presents a comprehensive assessment of the results obtained from observations of the cosmic shear in the last 15 years.
The next European cosmology mission starts construction
The space mission EUCLID, intended to map the universe in order to understand the influence of dark matter and dark energy, just passed the implementation phase.
