Joint Modelling of Astrophysical Systematics for Cosmology with LSST Cosmic Shear
Nikolina Å arÄeviÄ, 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…
