Surveying the Universe in 4D: Beating Cosmic Variance with Wide-Field Slitless Spectroscopy from HST, JWST, Euclid, Roman, and Beyond

Andreea Petric, Gaël Noirot, Stacey Alberts +71

We summarize strategies, lessons learned, and future directions from the Space Telescope Science Institute workshop Surveying the Universe in 4D: Beating Cosmic Variance with Wide-…

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…

UNIONS-3500 Weak Lensing: II. B-mode validation for cosmic shear

C. Daley, A. Guinot, S. Guerrini +9

At Stage-III sensitivities, cosmic shear modes unambiguously indicate systematic contamination and are often used to inform data selection and scale cuts for cosmological infer…
