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: methodology for derivation of IPC-corrected conversion gain of nonlinear CMOS APS
We introduce a fast method to measure the conversion gain in complementary metal-oxide-semiconductor active pixel sensors, which accounts for nonlinearity and...
Euclid: Photometric redshift calibration performance with the clustering-redshifts technique in the Flagship 2 simulation
Aims. The precision of cosmological constraints from imaging surveys hinges on an accurately estimated redshift distribution n(z) of the tomographic bins...
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: Star clusters in IC 342, NGC 2403, and Holmberg II
We examine the star cluster populations in the three nearby (3.20─3.45 Mpc) galaxies IC 342, NGC 2403, and Holmberg II, observed as part of the Euclid Early...
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...
