Euclid: Photometric redshift calibration with self-organising maps

W. Roster, A. H. Wright, H. Hildebrandt +173

The Euclid survey aims to trace the evolution of cosmic structures up to redshift 3 and beyond. Its success depends critically on obtaining highly accurate mean redshift…

Euclid Quick Data Release (Q1). The role of cosmic connectivity in shaping galaxy clusters

Euclid Collaboration, C. Gouin, C. Laigle +337

The matter distribution around galaxy clusters is distributed over several filaments, reflecting their positions as nodes in the large-scale cosmic web. The number of filaments con…

Euclid preparation LX. The use of HST images as input for weak-lensing image simulations

Euclid Collaboration, D. Scognamiglio, T. Schrabback +245

Data from the Euclid space telescope will enable cosmic shear measurements with very small statistical errors, requiring corresponding systematic error control level. A common appr…

Euclid: Testing photometric selection of emission-line galaxy targets

M. S. Cagliari, B. R. Granett, L. Guzzo +144

Multi-object spectroscopic galaxy surveys typically make use of photometric and colour criteria to select targets. Conversely, the Euclid NISP slitless spectrograph will record spe…

Euclid Preparation. XXXVII. Galaxy colour selections with Euclid and ground photometry for cluster weak-lensing analyses

Euclid Collaboration, G. F. Lesci, M. Sereno +238

We derived galaxy colour selections from Euclid and ground-based photometry, aiming to accurately define background galaxy samples in cluster weak-lensing analyses. Given any set o…
