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

no code implementations4 Nov 2020 Johannes U. Lange, Alexie Leauthaud, Sukhdeep Singh, Hong Guo, Rongpu Zhou, Tristan L. Smith, Francis-Yan Cyr-Racine

It has been shown that the lensing amplitude of galaxies in the Baryon Oscillation Spectroscopic Survey (BOSS) is lower than expected given their clustering properties.

Gravitational Lensing and the Power Spectrum of Dark Matter Substructure: Insights from the ETHOS N-body Simulations

1 code implementation31 Aug 2018 Ana Díaz Rivero, Cora Dvorkin, Francis-Yan Cyr-Racine, Jesús Zavala, Mark Vogelsberger

Comparing the amplitude and slope of the power spectrum on scales $0. 1 \lesssim k/$kpc$^{-1} \lesssim 10$ from lenses at different redshifts can help us distinguish between cold dark matter and other exotic dark matter scenarios that alter the abundance and central densities of subhalos.
