Brightest Cluster Galaxies Are Statistically Special From to

Roohi Dalal, Michael A. Strauss, Tomomi Sunayama +5

We study Brightest Cluster Galaxies (BCGs) in galaxy clusters from the Hyper Suprime-Cam (HSC) Subaru Strategic Program. The sample is selected over an area of 830 $\tex…

Dark Energy Survey internal consistency tests of the joint cosmological probes analysis with posterior predictive distributions

C. Doux, E. Baxter, P. Lemos +85

Beyond-CDM physics or systematic errors may cause subsets of a cosmological data set to appear inconsistent when analyzed assuming CDM. We present an application of internal…

Validating a minimal galaxy bias method for cosmological parameter inference using HSC-SDSS mock catalogs

Sunao Sugiyama, Masahiro Takada, Yosuke Kobayashi +4

We assess the performance of a perturbation theory inspired method for inferring cosmological parameters from the joint measurements of galaxy-galaxy weak lensing () and the pr…

Localizing Transformations of the Galaxy-Galaxy Lensing Observable

Youngsoo Park, Eduardo Rozo, Elisabeth Krause

Modern cosmological analyses of galaxy-galaxy lensing face a theoretical systematic effect arising from the non-locality of the observed galaxy-galaxy lensing signal. Because the p…

The impact of projection effects on cluster observables: stacked lensing and projected clustering

Tomomi Sunayama, Youngsoo Park, Masahiro Takada +6

An optical cluster finder inevitably suffers from projection effects, where it misidentifies a superposition of galaxies in multiple halos along the line-of-sight as a single clust…

Concordance Cosmology?

Youngsoo Park, Eduardo Rozo

We propose a new intuitive metric for evaluating the tension between two experiments, and apply it to several data sets. While our metric is non-optimal, if evidence of tension is…
