Dark Energy Survey Year 6 Results: fast and interpretable posterior predictive checks for correlated cosmic probes

C. Doux, J. Muir, A. Ferté +59

We present a fast and numerically stable framework for conducting posterior predictive distribution (PPD) tests of internal consistency in correlated cosmological probes. Our metho…

A Unified Tracer Analysis of DESI DR2 Baryon Acoustic Oscillations

N. Sanders, H. Seo, M. Rashkovetskyi +65

We improve upon previous efforts to optimally combine overlapping galaxy samples in the DESI baryon acoustic oscillation analysis. By weighting each galaxy by its linear bias, over…

Lyman Break Galaxy selection and redshift measurement with supervised contrastive learning

J. Choppin de Janvry, C. Yèche, Arjun Dey +55

Some of the next steps for high-precision cosmology lie within the high-redshift, high-density universe. Spectroscopic survey experiments such as the Dark Energy Spectroscopic Inst…

Quiescent Host Galaxies of Extended Quasars Revealed by Spectrophotometric Decomposition

Shengxiu Sun, Linhua Jiang, Zhiwei Pan +27

Previous works of low-redshift quasar host galaxies have focused on compact quasars and found that their host galaxies are mainly star-forming galaxies. Here we present a study of…

Alcock-Paczynski Blinding Scheme for the Ly- Forest Analysis

G. Perez-Sanchez, S. F. Beltran, G. Niz +45

We present and validate a blinding method for the Lyman- (Ly) forest analysis based on a modification of the Alcock-Paczynski test. In order to hide the background expansion…

Weak Evolution of Cosmic Atomic Hydrogen over the Past 4.5 Billion Years

Chuan-Peng Zhang, Hong Guo, Yizhou Gu +49

The cosmic star formation rate density (CSFRD) has declined sharply toward the present day, but the roles of the atomic and molecular gas reservoirs remain uncertain. We measure th…
