J. DeRose, R. H. Wechsler, M. R. Becker +114

We present a validation of the Dark Energy Survey Year 3 (DES Y3) -point analysis choices by testing them on Buzzard v2.0, a new suite of cosmological simulations that is…

DES Y3 + KiDS-1000: Consistent cosmology combining cosmic shear surveys

Dark Energy Survey, Kilo-Degree Survey Collaboration, : +160

We present a joint cosmic shear analysis of the Dark Energy Survey (DES Y3) and the Kilo-Degree Survey (KiDS-1000) in a collaborative effort between the two survey teams. We find c…

Dark Energy Survey Year 3 Results: Constraints on cosmological parameters and galaxy bias models from galaxy clustering and galaxy-galaxy lensing using the redMaGiC sample

S. Pandey, E. Krause, J. DeRose +138

We constrain cosmological and galaxy-bias parameters using the combination of galaxy clustering and galaxy-galaxy lensing measurements from the Dark Energy Survey Year-3 data. We d…
