Beyond the 3rd moment: A practical study of using lensing convergence CDFs for cosmology with DES Y3

Understand

Widefield surveys of the sky probe many clustered scalar fields -- such as galaxy counts, lensing potential, gas pressure, etc.

• -- that are sensitive to different cosmological and astrophysical processes.
• Our ability to constrain such processes from these fields depends crucially on the statistics chosen to summarize the field.
• In this work, we explore the cumulative distribution function (CDF) at multiple scales as a summary of the galaxy lensing convergence field.
