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...
Euclid: Improving the efficiency of weak lensing shear bias calibration. Pixel noise cancellation and the response method on trial
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...
Euclid: Relativistic effects in the dipole of the two-point correlation function
Gravitational redshift and Doppler effects give rise to an antisymmetric component of the galaxy correlation function when cross-correlating two galaxy...
Euclid: Searches for strong gravitational lenses using convolutional neural nets in Early Release Observations of the Perseus field
The Euclid Wide Survey (EWS) is predicted to find approximately 170 000 galaxy-galaxy strong lenses from its lifetime observation of 14 000 deg 2 of the sky...
Euclid: Testing photometric selection of emission-line galaxy targets
Multi-object spectroscopic galaxy surveys typically make use of photometric and colour criteria to select their targets. That is not the case of Euclid, which...
Euclid: Testing the Copernican principle with next-generation surveys
Context. The Copernican principle, the notion that we are not at a special location in the Universe, is one of the cornerstones of modern cosmology. Its...
