This work, together with its companion paper, Secco, Samuroff et al., present the Dark Energy Survey Year 3 cosmic-shear measurements and cosmological constraints based on an analysis of over 100 million source galaxies.

17/03/2022 The PDF perspective on the tracer-matter connection: Lagrangian bias and non-Poissonian shot noise

We study the connection of matter density and its tracers from the probability density function (PDF) perspective.

24/08/2022 Photometric Redshifts for Next-Generation Surveys
