Joint inference of multiplicative and additive systematics in galaxy density fluctuations and clustering measurements
Federico Berlfein, Rachel Mandelbaum, Scott Dodelson +1
Galaxy clustering measurements are a key probe of the matter density field in the Universe. With the era of precision cosmology upon us, surveys rely on precise measurements of the…

Accurate field-level weak lensing inference for precision cosmology
Alan Junzhe Zhou, Xiangchong Li, Scott Dodelson +1
We present , a catalog-to-cosmology pipeline for general flat-sky field-level inference, which provides access to cosmological information beyond the two-point stati…

SPT Clusters with DES and HST Weak Lensing. I. Cluster Lensing and Bayesian Population Modeling of Multi-Wavelength Cluster Datasets
S. Bocquet, S. Grandis, L. E. Bleem +130
We present a Bayesian population modeling method to analyze the abundance of galaxy clusters identified by the South Pole Telescope (SPT) with a simultaneous mass calibration using…
