Euclid preparation

Astronomy & Astrophysics
The Euclid Space Telescope will image about 14 000 deg2 of the extragalactic sky at visible and near-infrared wavelengths, providing a dataset of unprecedented size and richness that will facilitate a multitude of studies into the evolution of galaxies ...

Euclid preparation LXIV. The Cosmic Dawn Survey (DAWN) of the Euclid Deep and Auxiliary Fields

Astronomy & Astrophysics
will provide deep near-infrared (NIR) imaging to ∼26.5 AB magnitude over ∼59 deg^2 in its deep and auxiliary fields. The Cosmic DAWN survey combines dedicated and archival UV--NIR observations to provide matched depth multiwavelength imaging of the deep ...

Euclid preparation. L. Calibration of the halo linear bias in Lambda(u)CDM cosmologies

Astronomy & Astrophysics
The mission, designed to map the geometry of the dark Universe, presents an unprecedented opportunity for advancing our understanding of the cosmos through its photometric galaxy cluster survey. Central to this endeavor is the accurate calibration of the

Euclid preparation. LXX. Forecasting detection limits for intracluster light in the Euclid Wide Survey

Astronomy & Astrophysics
The intracluster light (ICL) permeating galaxy clusters is a tracer of the cluster assembly history and potentially a tracer of their dark matter structure.

Euclid preparation. LXXVI. Simulating thousands of Euclid spectroscopic skies

Astronomy & Astrophysics
We present two extensive sets of 3500$+$1000 simulations of dark matter haloes on the past light cone and two corresponding sets of simulated (mock) galaxy catalogues that represent the spectroscopic sample of Euclid.

Euclid preparation. LXXXV. Toward a DR1 application of higher-order weak lensing statistics

Astronomy & Astrophysics
This is the second paper in the HOWLS (higher-order weak lensing statistics) series exploring the usage of non-Gaussian statistics for cosmology inference within . With respect to our first paper, we develop a full tomographic analysis based on realistic

Euclid preparation. LXXII. Three-dimensional galaxy clustering in configuration space. 1. Two-point correlation function estimation

Astronomy & Astrophysics
The two-point correlation function of the galaxy spatial distribution is a major cosmological observable that enables constraints on the dynamics and geometry of the Universe. The Euclid mission is aimed at performing an extensive spectroscopic survey of

Euclid preparation. LXXXIV. The flat-sky approximation for the clustering of Euclid's photometric galaxies

Astronomy & Astrophysics
We compared the performance of the flat-sky approximation and Limber approximation for the clustering analysis of the photometric galaxy catalogue of Euclid.

Euclid preparation. LXVIII. Extracting physical parameters from galaxies with machine learning

Astronomy & Astrophysics
The mission is generating a vast amount of imaging data in four broadband filters at a high angular resolution. This data will allow for the detailed study of mass, metallicity, and stellar populations across galaxies that will constrain their formation ...

Euclid preparation. LXXXI. The impact of nonparametric star formation histories on spatially resolved galaxy property estimation using synthetic Euclid images

Astronomy & Astrophysics
We analyzed the spatially resolved and global star formation histories (SFHs) for a sample of 25 TNG50- SKIRT Atlas galaxies to assess the feasibility of reconstructing accurate SFHs from Euclid-like data.
