Euclid Quick Data Release (Q1) -- Data release overview
Euclid Collaboration, H. Aussel, I. Tereno +407
The first Euclid Quick Data Release, Q1, comprises 63.1 sq deg of the Euclid Deep Fields (EDFs) to nominal wide-survey depth. It encompasses visible and near-infrared space-based i…
Breaking the degeneracy in stellar spectral classification from single wide-band images
Ezequiel Centofanti, Samuel Farrens, Jean-Luc Starck +3
The spectral energy distribution (SED) of observed stars in wide-field images is crucial for chromatic point spread function (PSF) modelling methods, which use unresolved stars as…
Euclid preparation: XLVIII. The pre-launch Science Ground Segment simulation framework
Euclid Collaboration, S. Serrano, P. Hudelot +274
The European Space Agency's Euclid mission is one of the upcoming generation of large-scale cosmology surveys, which will map the large-scale structure in the Universe with unprece…
Euclid preparation. XLI. Galaxy power spectrum modelling in real space
Euclid Collaboration, A. Pezzotta, C. Moretti +246
We investigate the accuracy of the perturbative galaxy bias expansion in view of the forthcoming analysis of the Euclid spectroscopic galaxy samples. We compare the performance of…
Euclid preparation. XXXI. The effect of the variations in photometric passbands on photometric-redshift accuracy
Euclid Collaboration, Stéphane Paltani, J. Coupon +214
The technique of photometric redshifts has become essential for the exploitation of multi-band extragalactic surveys. While the requirements on photo-zs for the study of galaxy evo…
Euclid preparation. XXIX. Water ice in spacecraft part I: The physics of ice formation and contamination
Euclid Collaboration, M. Schirmer, K. Thürmer +218
Molecular contamination is a well-known problem in space flight. Water is the most common contaminant and alters numerous properties of a cryogenic optical system. Too much ice mea…
Euclid preparation. XXVII. A UV-NIR spectral atlas of compact planetary nebulae for wavelength calibration
Euclid Collaboration, K. Paterson, M. Schirmer +201
The Euclid mission will conduct an extragalactic survey over 15000 deg of the extragalactic sky. The spectroscopic channel of the Near-Infrared Spectrometer and Photometer (NIS…
Euclid preparation: XXVIII. Modelling of the weak lensing angular power spectrum
Euclid Collaboration, A. C. Deshpande, T. Kitching +200
This work considers which higher-order effects in modelling the cosmic shear angular power spectra must be taken into account for Euclid. We identify which terms are of concern, an…
Euclid preparation. XXVII. Covariance model validation for the 2-point correlation function of galaxy clusters
Euclid Collaboration, A. Fumagalli, A. Saro +191
Aims. We validate a semi-analytical model for the covariance of real-space 2-point correlation function of galaxy clusters. Methods. Using 1000 PINOCCHIO light cones mimicking the…
The DESI Experiment Part II: Instrument Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectropic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations and the growth of structure through redshift…
The DESI Experiment Part I: Science,Targeting, and Survey Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through…
A new method to measure galaxy bias
Jennifer E. Pollack, Robert E. Smith, Cristiano Porciani
We present a new approach for modelling galaxy/halo bias that utilizes the full non-linear information contained in the moments of the matter density field, which we derive using a…
Modelling large-scale halo bias using the bispectrum
Jennifer E. Pollack, Robert E. Smith, Cristiano Porciani
We study the relation between the halo and matter density fields -- commonly termed bias -- in the LCDM framework. In particular, we examine the local model of biasing at quadratic…
