Galaxy Formation at Cosmic Noon
1 June 2020: A project started ten years ago by NSF’s NOIRLab Director Patrick McCarthy, then an astronomer at the Carnegie Institution for Science, and fellow Carnegie scientist Daniel Kelson, has come to fruition this month with the results of theCarnegie-Spitzer-IMACS (CSI) Redshift Survey being published in the Monthly Notices of the Royal Astronomical Society. The Universe is filled with galaxies like the one we live in, the Milky Way. Spread out across the sky, their distribution is not random — galaxies are instead laid out in patterns, groupings, and correlations known as large-scale structure. The goal of the CSI Redshift Survey was to understand how this structure affects the growth and evolution of galaxies. To study this, the team needed to collect many data points, including distances, luminosities, colors and — most importantly — mass, for half a million galaxies. Back in 2003, before embarking on this survey, McCarthy was involved in …
