Nearest Neighbor distributions: new statistical measures for cosmological clustering

Kavli Affiliate: Tom Abel | First 5 Authors: Arka Banerjee, Tom Abel, , , | Summary: The use of summary statistics beyond the two-point correlation function to analyze the non-Gaussian clustering on small scales is an active field of research in cosmology. In this paper, we explore a set of new summary statistics — the […]

Illuminating Dark Matter Halo Density Profiles Without Subhaloes

Kavli Affiliate: Risa Wechsler | First 5 Authors: Catherine E. Fielder, Yao-Yuan Mao, Andrew R. Zentner, Jeffrey A. Newman, Hao-Yi Wu | Summary: Cold dark matter haloes consist of a relatively smooth dark matter component as well as a system of bound subhaloes. It is the prevailing practice to include all halo mass, including mass […]

On the Chemical Abundance of HR 8799 and the Planet c

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Ji Wang, Jason Wang, Bo Ma, Jeffrey Chilcote, Steve Ertel | Summary: Comparing chemical abundances of a planet and the host star reveals the origin and formation path. Stellar abundance is measured with high-resolution spectroscopy. Planet abundance, on the other hand, is usually inferred from low-resolution data. […]
