Journal ArticleDOI
Concentrations of dark haloes emerge from their merger histories
Kuan Wang,Yao-Yuan Mao,Andrew R. Zentner,Johannes U Lange,Johannes U Lange,Frank C. van den Bosch,Risa H. Wechsler,Risa H. Wechsler +7 more
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
Johannes U Lange,Johannes U Lange,Alexie Leauthaud,Sukhdeep Singh,Sukhdeep Singh,Hong Guo,Rongpu Zhou,Tristan L. Smith,Francis-Yan Cyr-Racine +8 more
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.
Journal ArticleDOI
Five per cent measurements of the growth rate from simulation-based modelling of redshift-space clustering in BOSS LOWZ
Johannes U Lange,Johannes U Lange,Andrew Hearin,Alexie Leauthaud,Frank C. van den Bosch,Hong Guo,J. DeRose,J. DeRose +7 more
TL;DR: In this paper, the authors used a simulation-based approach to analyse the anisotropic clustering of the BOSS LOWZ sample over the radial range of low-redshift observations.

The Outer Stellar Mass of Massive Galaxies: A Simple Tracer of Halo Mass with Scatter Comparable to Richness and Reduced Projection Effects
Song Huang,Alexie Leauthaud,Christopher Bradshaw,Andrew Hearin,Peter Behroozi,Johannes U Lange,Jenny E. Greene,J. DeRose,Joshua S. Speagle,Enia Xhakaj +9 more
TL;DR: In this article, the potential of different stellar mass estimates in tracing halo mass was studied using weak gravitational lensing data from the Hyper Suprime-Cam Subaru Strategic Program (HSC survey).
