TL;DR: The DESI Bright Galaxy Survey (BGS) as discussed by the authors was designed to produce the most detailed map of the universe during the dark energy-dominated epoch with redshifts of >10 million galaxies spanning 14,000 deg2.

TL;DR: The 2020s are poised to continue the past 15 years of significant advances based on the discovery and follow-up of nearby dwarf galaxies as mentioned in this paper, and Maximizing the scientific impact of dwarfs discovered in upcoming imaging surveys will require both major spectroscopic surveys on 6-10m telescopes and multiplexed spectroscopy with even larger apertures.

TL;DR: In this article, the authors show that misidentifying H$\beta$ emitter as [O III] emitter will cause a shift in the inferred radial position of the galaxy by approximately 90 Mpc/h.

TL;DR: In this paper, the authors used high-resolution dissipationless simulations of the concordance flat LCDM model to make predictions for the galaxy-mass correlations and compare them to the recent SDSS weak lensing measurements.

TL;DR: SPOKES (SPectrOscopic KEn Simulation), an end-to-end simulation facility for spectroscopic cosmological surveys designed to address this challenge, is presented and the architecture, first science, and computational performance results are presented.
