Journal ArticleDOI

Concentrations of dark haloes emerge from their merger histories

TL;DR: In this paper, a suite of cosmological $N$-body simulations is used to investigate how halo concentration evolves with time and emerges from the mass assembly history, and the origin of the scatter in the relation between concentration and assembly history.
Journal ArticleDOI

On the halo-mass and radial scale dependence of the lensing is low effect

TL;DR: In this article, the authors present new measurements and modelling of galaxies in the Baryon Oscillation Spectroscopic Survey (BOSS) low-lowz sample, focusing on the radial and stellar mass dependence of the lensing amplitude mis-match and find an amplitude mismatch of around $35\%$ when assuming the canonical $Lambda$CDM with Planck Cosmological Microwave Background (CMB) constraints.
