UNIONS: The Ultraviolet Near-Infrared Optical Northern Survey
Stephen Gwyn, Alan W. McConnachie, Jean-Charles Cuillandre +86
The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada-France-Hawai'i Telescope, the Pan-STARRS telescopes,…
Cosmology from UNIONS weak lensing profiles of galaxy clusters
Charlie T. Mpetha, James E. Taylor, Yuba Amoura +12
Cosmological information is encoded in the structure of galaxy clusters. In Universes with less matter and larger initial density perturbations, clusters form earlier and have more…
Galaxy-Point Spread Function correlations as a probe of weak-lensing systematics with UNIONS data
Sacha Guerrini, Martin Kilbinger, Hubert Leterme +6
Weak gravitational lensing requires precise measurements of galaxy shapes and therefore an accurate knowledge of the PSF model. The latter can be a source of systematics that affec…
UNIONS: a direct measurement of intrinsic alignment with BOSS/eBOSS spectroscopy
Fabian Hervas Peters, Martin Kilbinger, Romain Paviot +12
During their formation, galaxies are subject to tidal forces, which create correlations between their shapes and the large-scale structure of the Universe, known as intrinsic align…
Euclid preparation. Sensitivity to neutrino parameters
Euclid Collaboration, M. Archidiacono, J. Lesgourgues +246
The Euclid mission of the European Space Agency will deliver weak gravitational lensing and galaxy clustering surveys that can be used to constrain the standard cosmological model…
Point-Spread Function errors for weak lensing - density cross-correlations. Application to UNIONS
Ziwen Zhang, Martin Kilbinger, Fabian Hervas Peters +8
Aims:Calibrating the point spread function (PSF) is a fundamental part of weak gravitational lensing analyses. Even with corrected galaxy images, imperfect calibrations can introdu…
Black-Hole-to-Halo Mass Relation From UNIONS Weak Lensing
Qinxun Li, Martin Kilbinger, Wentao Luo +17
This letter presents, for the first time, direct constraints on the black-hole-to-halo-mass relation using weak gravitational lensing measurements. We construct type I and type II…
Constraining Hot Dark Matter Sub-Species with Weak Lensing and the Cosmic Microwave Background Radiation
Fabian Hervas Peters, Aurel Schneider, Jozef Bucko +2
Although it is well known that the bulk of dark matter (DM) has to be cold, the existence of an additional sub-dominant, hot species remains a valid possibility. In this paper we i…
Probing the two-body decaying dark matter scenario with weak lensing and the cosmic microwave background
Jozef Bucko, Sambit K. Giri, Fabian Hervas Peters +1
Decaying dark matter (DDM) scenarios have recently regained attention due to their potential ability to resolve the well-known clustering (or ) tension between weak lensing (W…
