Abstract

We present angular diameter measurements obtained by measuring the position of baryon acoustic oscillations (BAO) in an optimized sample of galaxies from the first three years of Dark Energy Survey data (DES Y3). The sample consists of 7 million galaxies distributed over a footprint of 4100 deg2 with 0.6<zphoto[removed]0.75. When combined with DES 3x2pt+SNIa, they lead to improvements in H0 and ωm constraints by ∼20%. © 2022 American Physical Society.
