Quintom Model Perturbations
L. W. K. Goh, A. N. Taylor
We build upon the work of Goh and Taylor 2025, in which we proposed a two scalar field quintom framework capable of naturally realising a phantom-to-quintessence transition in the…
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…
cloelib: A Flexible Python Library for Computing Cosmological Observables in the Euclid Era
Marco Bonici, Guadalupe Cañas-Herrera, Pedro Carrilho +54
cloelib is a Python library developed to compute cosmological observables within the Cosmology Likelihood for Observables in Euclid (CLOE) ecosystem (cloe-org). As cosmology enters…
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…
