Mapping dark matter and the emergence of large-scale structure

TL;DR

This paper proposes a survey using a large spectrograph on a 10m telescope to map dark matter and large-scale cosmic structures up to redshifts of 1.5 or 3.5, enhancing our understanding of the universe's composition.

Contribution

It introduces a new survey plan utilizing a multiplexed spectrograph on a large telescope to study dark matter and cosmic structure formation at high redshifts.

Findings

Potential to map dark matter distribution up to z~3.5

Use of a massively multiplexed spectrograph on a 10m telescope

Advancement in understanding large-scale structure emergence

Abstract

We discuss a potential survey to map dark matter and the emergence of large-scale structure to redshift z ~ 1.5 (baseline) or z~3.5 (with near-IR extension) using a massively multiplexed spectrograph on a 10m-class telescope, such as the proposed Widefield Spectroscopic Telescope.
