In a purely cold dark matter universe, the initial matter power spectrum and its subsequent gravitational growth contain no special massor time-scales, and so neither do the emergent population statistics of internal dark matter (DM) halo properties. Using 1.5 million haloes from three IllustrisTNG realizations of a ΛCDM universe, we show that galaxy formation physics drives non-monotonic features (“wiggles”) into DM property statistics across six decades in halo mass, from dwarf galaxies to… 

Correlations of Dark Matter, Gas, and Stellar Profiles in Dark Matter Halos

Halos of similar mass and redshift exhibit a large degree of variability in their differential properties, such as dark matter, hot gas, and stellar mass density profiles. This variability is an

The Odd Dark Matter Halos of Isolated Gas-rich Ultradiffuse Galaxies

We analyze circular velocity profiles of seven ultradiffuse galaxies (UDGs) that are isolated and gas-rich. Assuming that the dark matter halos of these UDGs have a Navarro–Frenk–White (NFW) density

KLLR: A Scale-dependent, Multivariate Model Class for Regression Analysis

TLDR
This work introduces and implements a class of kernel localized linear regression (KLLR) models, a natural extension to the commonly used linear models that allows the parameters of the linear model—normalization, slope, and covariance matrix—to be scale dependent.
