The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy...

This paper presents the specification, design, and development of the Visible Camera (VIS) on the European Space Agency's Euclid mission. VIS is a large optical...

The Near-Infrared Spectrometer and Photometer (NISP) on board the Euclid satellite provides multiband photometry and R ≳ 450 slitless grism spectroscopy in the...

The Euclid mission of the European Space Agency seeks to understand the Universe's expansion history and the nature of dark energy, through measurements of...

To obtain an accurate cosmological inference from upcoming weak lensing surveys such as the one conducted by Euclid, the shear measurement requires calibration...

The near-infrared calibration unit (NI-CU) on board Euclid's Near-Infrared Spectrometer and Photometer (NISP) is the first astronomical calibration lamp based...

We introduce a fast method to measure the conversion gain in complementary metal-oxide-semiconductor active pixel sensors, which accounts for nonlinearity and...

This study explores the impact of observational and modelling systematic effects on cluster number counts and cluster clustering and provides model...

The tomographic approach to analysing the 3 × 2 pt signal involves dividing the observed galaxy sample into a configuration of redshift bins. We present a...
