Dissecting the Perseus-Pisces supercluster observed with CFHT-MegaCam: Exploring late-type galaxy shape alignments within the local cosmic web
M. Mondelin, S. Codis, J. -C. Cuillandre +2
Intrinsic alignments of galaxy shapes are a major systematic for weak gravitational lensing and provide insight into how galaxies acquire orientations within the cosmic web. Most s…
UNIONS-3500 Weak Lensing: I. A Galaxy Shape Catalogue in the Northern Sky
F. Hervas-Peters, S. Guerrini, M. Kilbinger +15
Weak gravitational lensing has become a widely used effect to characterise the dark-matter distribution on large scales in the Universe by measuring galaxy ellipticities and their…
UNIONS-3500 Weak Lensing: III. 2D Cosmological Constraints in Configuration Space
L. W. K. Goh, S. Guerrini, C. Daley +13
We present the first cosmological constraints from the cosmic shear analysis of the UNIONS-3500 weak lensing galaxy catalogue in configuration space. The Ultraviolet Near Infrared…
Euclid preparation. Decomposing components of the extragalactic background light using multi-band intensity mapping cross-correlations
Euclid Collaboration, Y. Cao, A. R. Cooray +269
The extragalactic background light (EBL) fluctuations in the optical/near-IR encode the cumulative integrated galaxy light (IGL), diffuse intra-halo light (IHL), and high- sourc…
Euclid: Early Release Observations. A combined strong and weak lensing solution for Abell 2390 beyond its virial radius
J. M. Diego, G. Congedo, R. Gavazzi +183
Euclid is presently mapping the distribution of matter in the Universe in detail via the weak lensing (WL) signature of billions of distant galaxies. The WL signal is most prominen…
Euclid: Early Release Observations. Weak gravitational lensing analysis of Abell 2390
T. Schrabback, G. Congedo, R. Gavazzi +196
The Euclid space telescope of the European Space Agency (ESA) is designed to provide sensitive and accurate measurements of weak gravitational lensing distortions over wide areas o…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
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…
ShapePipe: a new shape measurement pipeline and weak-lensing application to UNIONS/CFIS data
Axel Guinot, Martin Kilbinger, Samuel Farrens +16
UNIONS is an ongoing collaboration that will provide the largest deep photometric survey of the Northern sky in four optical bands to date. As part of this collaboration, CFIS is t…
