Assessing the large-scale angular clustering of UNIONS Lyman Break Galaxies via cross-correlations
Constantin Payerne, Christophe Yèche, William d'Assignies Doumerg +8
Lyman-break galaxies (LBGs), selected via the strong spectral break blueward of the Lyman limit, are powerful tracers of large-scale structure at redshifts . In this work, we…
Measuring satellite galaxy subhalo masses in redMaPPer clusters with UNIONS weak lensing data
Roman Akhmetshyn, Jack Elvin-Poole, Michael J. Hudson +13
In this work, we present the observed galaxy-galaxy lensing signal of satellite galaxies in rich clusters obtained from the Ultraviolet Near-Infrared Optical Northern Survey (UNION…
Revisiting the 'Lensing is Low' Problem with UNIONS
Martine C. T. Campbell, Jack Elvin-Poole, Michael J. Hudson +11
We present new measurements of the galaxy-galaxy lensing (GGL) signal around Baryon Oscillation Spectroscopic Survey (BOSS) CMASS galaxies using background sources from the Ultravi…
UNIONS-3500 Weak Lensing: IV. 2D cosmological constraints in harmonic space
S. Guerrini, L. W. K. Goh, F. Hervas-Peters +14
The Ultraviolet Near Infrared Optical Northern Survey (UNIONS) is a photometric survey in the northern sky. The quality of the data in the band provides precise shape measureme…
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…
