Probabilistic characterization of blending with LSST and application to cluster lensing cosmology
Manon Ramel, Cyrille Doux, Marine Kuna +9
Next-generation galaxy surveys, like the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST), will deliver unprecedented depth and sky coverage, enabling precise mea…
A Path to an All-Sky Survey with Roman
Jiwon Jesse Han, Anirudh Chiti, Kai-Feng Chen +93
A deep, space-based, all-sky near-infrared survey carried out with the Nancy Grace Roman Space Telescope would constitute a foundational astronomical infrastructure for decades to…
Impact and interplay of CDM analysis choices for LSST cosmic shear
N. C. Robertson, C. Heymans, J. Zuntz +9
We forecast cosmological parameter constraints for a cosmic shear analysis of the Rubin Observatory Legacy Survey of Space and Time (LSST), defining an analysis framework that can…
Non-linear infusion of intrinsic alignment and source clustering: impact on non-Gaussian cosmic shear statistics
J. Harnois-Déraps, N. Šarčević, L. Medina Varela +15
Intrinsic alignments (IA) of galaxies is one of the key secondary signals to cosmic shear measurements, and must be modeled to interpret weak lensing data and infer the correct cos…
Joint Modelling of Astrophysical Systematics for Cosmology with LSST Cosmic Shear
Nikolina Šarčević, C. Danielle Leonard, Markus M. Rau +1
We present a novel framework for jointly modelling the weak lensing source galaxy redshift distribution and the intrinsic alignment of galaxies via a shared luminosity function (LF…
