What to expect from dynamical modelling of cluster haloes II. Investigating dynamical state indicators with Random Forest
Qingyang Li, Jiaxin Han, Wenting Wang +5
We investigate the importances of various dynamical features in predicting the dynamical state (DS) of galaxy clusters, based on the Random Forest (RF) machine learning approach. W…
Snowmass2021 Cosmic Frontier White Paper: Prospects for obtaining Dark Matter Constraints with DESI
Monica Valluri, Solene Chabanier, Vid Irsic +29
Despite efforts over several decades, direct-detection experiments have not yet led to the discovery of the dark matter (DM) particle. This has led to increasing interest in altern…
FPFS Shear Estimator: Systematic Tests on the Hyper Suprime-Cam Survey First Year Data
Xiangchong Li, Masamune Oguri, Nobuhiko Katayama +6
We apply the Fourier Power Function Shapelets (FPFS) shear estimator to the first year data of the Hyper Suprime-Cam survey to construct a shape catalog. The FPFS shear estimator h…
The multidimensional dependence of halo bias in the eye of a machine: a tale of halo structure, assembly and environment
Jiaxin Han, Yin Li, Yipeng Jing +3
We develop a novel approach in exploring the joint dependence of halo bias on multiple halo properties using Gaussian process regression. Using a CDM -body simulation, we car…
A weak gravitational lensing recalibration of the scaling relations linking the gas properties of dark halos to their mass
Wenting Wang, Simon White, Rachel Mandelbaum +3
We use weak gravitational lensing to measure mean mass profiles around Locally Brightest Galaxies (LBGs). These are selected from the SDSS/DR7 spectroscopic and photometric catalog…
Constraints on the missing baryons from the kinetic Sunyaev-Zeldovich effect in Planck data
Carlos Hernández-Monteagudo, Yin-zhe Ma, Francisco-Shu Kitaura +4
We estimate the amount of the {\it missing baryons} detected by the \Planck\ measurements of the cosmic microwave background in the direction of Central Galaxies (CGs) identified i…
