Snowmass 2021 CMB-S4 White Paper
Kevork Abazajian, Arwa Abdulghafour, Graeme E. Addison +353
This Snowmass 2021 White Paper describes the Cosmic Microwave Background Stage 4 project CMB-S4, which is designed to cross critical thresholds in our understanding of the origin a…
Shock and Splash: Gas and Dark Matter Halo Boundaries around LambdaCDM Galaxy Clusters
Han Aung, Daisuke Nagai, Erwin T. Lau
Recent advances in simulations and observations of galaxy clusters suggest that there exists a physical outer boundary of massive cluster-size dark matter haloes. In this work, we…
Measuring Cosmological Distances Using Cluster Edges as a Standard Ruler
Erika L. Wagoner, Eduardo Rozo, Han Aung +1
The line-of-sight velocity dispersion profile of galaxy clusters exhibits a "kink" corresponding to the spatial extent of orbiting galaxies. Because the spatial extent of a cluster…
Clusters Have Edges: The Projected Phase SpaceStructure of SDSS redMaPPer Clusters
Paxton Tomooka, Eduardo Rozo, Erika L. Wagoner +3
We study the distribution of line-of-sight velocities of galaxies in the vicinity of SDSS redMaPPer galaxy clusters. Based on their velocities, galaxies can be split into two categ…
The Phase Space Structure of Dark Matter Halos
Han Aung, Daisuke Nagai, Eduardo Rozo +1
The phase space structure of dark matter halos can be used to measure the mass of the halo, infer mass accretion rates, and probe the effects of modified gravity. Previous studies…
Ly Blobs from Cold Streams Undergoing Kelvin-Helmholtz Instabilities
Nir Mandelker, Frank C. van den Bosch, Daisuke Nagai +3
We present an analytic toy model for the radiation produced by the interaction between the cold streams thought to feed massive halos at high redshift and their hot CGM. We begin b…
