Cluster cosmology with anisotropic boosts: Validation of a novel forward modeling analysis and application on SDSS redMaPPer clusters
Youngsoo Park, Tomomi Sunayama, Masahiro Takada +5
We present a novel analysis for cluster cosmology that fully forward models the abundances, weak lensing, and the clustering of galaxy clusters. Our analysis notably includes an em…
Cosmological inference from the emulator based halo model II: Joint analysis of galaxy-galaxy weak lensing and galaxy clustering from HSC-Y1 and SDSS
Hironao Miyatake, Sunao Sugiyama, Masahiro Takada +25
We present high-fidelity cosmology results from a blinded joint analysis of galaxy-galaxy weak lensing () and projected galaxy clustering () measured from the Hype…
HSC Year 1 cosmology results with the minimal bias method: HSCBOSS galaxy-galaxy weak lensing and BOSS galaxy clustering
Sunao Sugiyama, Masahiro Takada, Hironao Miyatake +23
We present cosmological parameter constraints from a blinded joint analysis of galaxy-galaxy weak lensing, , and projected correlation function, , measure…
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…
Cosmological inference from emulator based halo model I: Validation tests with HSC and SDSS mock catalogs
Hironao Miyatake, Yosuke Kobayashi, Masahiro Takada +7
We present validation tests of emulator-based halo model method for cosmological parameter inference, assuming hypothetical measurements of the projected correlation function of ga…
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…
Cosmology from large scale galaxy clustering and galaxy-galaxy lensing with Dark Energy Survey Science Verification data
Juliana Kwan, Carles Sanchez, Joseph Clampitt +80
We present cosmological constraints from the Dark Energy Survey (DES) using a combined analysis of angular clustering of red galaxies and their cross-correlation with weak gravitat…
External priors for the next generation of CMB experiments
Alessandro Manzotti, Scott Dodelson, Youngsoo Park
Planned cosmic microwave background (CMB) experiments can dramatically improve what we know about neutrino physics, inflation, and dark energy. The low level of noise, together wit…
Detectability of Weak Lensing Modifications under Galileon Theories
Youngsoo Park, Mark Wyman
Theories of modified gravity attempt to reconcile physics at the largest and the smallest scales by explaining the accelerated expansion of our universe without introducing the cos…
