Cosmology with galaxy-galaxy lensing on non-perturbative scales: Emulation method and application to BOSS LOWZ
Benjamin D. Wibking, David H. Weinberg, Andrés N. Salcedo +5
We describe our nonlinear emulation (i.e., interpolation) framework that combines the halo occupation distribution (HOD) galaxy bias model with -body simulations of nonlinear st…
Cosmological constraints from galaxy-lensing cross correlations using BOSS galaxies with SDSS and CMB lensing
Sukhdeep Singh, Rachel Mandelbaum, Uroš Seljak +2
We present cosmological parameter constraints based on a joint modeling of galaxy-lensing cross correlations and galaxy clustering measurements in the SDSS, marginalizing over smal…
The mass-size relation of LRGs from BOSS and DECaLS
Ginevra Favole, Antonio D. Montero-Dorta, Francisco Prada +2
We use the DECaLS DR3 survey photometry matched to the SDSS-III/BOSS DR12 spectroscopic catalog to investigate the morphology and stellar mass-size relation of luminous red galaxie…
The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: double-probe measurements from BOSS galaxy clustering \& Planck data -- towards an analysis without informative priors
Marcos Pellejero-Ibanez, Chia-Hsun Chuang, J. A. Rubiño-Martín +28
We develop a new methodology called double-probe analysis with the aim of minimizing informative priors in the estimation of cosmological parameters. We extract the dark-energy-mod…
