On the impact of the galaxy window function on cosmological parameter estimation Permalink

Published in Monthly Notices of the Royal Astronomical Society, 2023

This paper identifies a new source of observational systematics in large-scale structure survey analysis stemming from the bias in measuring imaging systematics weights. This paper is the second chapter of my Ph.D. dissertation.
