OzDES Reverberation Mapping Program: CIV lags from six years of data

A. Penton, H. McDougall, T. M. Davis +52

The paper reports 29 successful CIV reverberation time‑lag measurements for high‑redshift active galactic nuclei from the OzDES survey, derives black‑hole masses of 0.8–1.3 billion…

Dimensional reduction for sampled priors and application to photometric redshift distributions

Gary Bernstein, William Assignies Doumerg, Michael A. Troxel +35

A typical Bayesian inference on the values of some parameters of interest from some data involves running a Markov Chain (MC) to sample from the posterior $p({\bf q},{\…

Dark Energy Survey: Galaxy Sample for the Baryonic Acoustic Oscillation Measurement from the Final Dataset

J. Mena-Fernández, M. Rodríguez-Monroy, S. Avila +85

In this paper we present and validate the galaxy sample used for the analysis of the baryon acoustic oscillation (BAO) signal in the Dark Energy Survey (DES) Y6 data. The definitio…

Constraining the Stellar-to-Halo Mass Relation with Galaxy Clustering and Weak Lensing from DES Year 3 Data

G. Zacharegkas, C. Chang, J. Prat +100

We develop a framework to study the relation between the stellar mass of a galaxy and the total mass of its host dark matter halo using galaxy clustering and galaxy-galaxy lensing…
