SDSS Galaxies (SDSS galaxies as imaged by DESI)
This is a dataset of 306,006 galaxies whose coordinates are taken from the Sloan Digital Sky Survey Data Release 7 and a modified catalogue from Brinchmann+2003 and Wilman+2010. This volume complete sample has an r-band absolute magnitude limit of Mᵣ≤-20 and a redshift limit of z≤0.08. See Arora+2019 for details.
This catalogue covers a wide range of environments from clusters to groups and field systems. The galaxy images are taken from the Dark Energy Spectroscopic Instrument, and contain g, r, and z bands.

Papers archive 2025-07-28
1 shown of 1 paper with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 1. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
| Date | Samples run Syntology | |||
