We have produced a new conformal map of the universe illustrating recent discoveries, ranging from Kuiper Belt objects in the solar system to the galaxies and quasars from the Sloan Digital Sky Survey. This map projection, based on the logarithm map of the complex plane, preserves shapes locally and yet is able to display the entire range of astronomical scales from the Earth's neighborhood to the cosmic microwave background. The conformal nature of the projection, preserving shapes locally, may be of particular use for analyzing large-scale structure. Prominent in the map is a Sloan Great Wall of galaxies 1.37 billion light-years long, 80% longer than the Great Wall discovered by Geller and Huchra and therefore the largest observed structure in the universe.

Internal and Collective Properties of Galaxies in the Sloan Digital Sky Survey (2006, background): “The LF of the deeper D4 sample, which includes the Sloan Great Wall (Gott et al. 2005), shows the highest density of early type galaxies among all five volume-limited samples, and thus its LF seems less representative.”
The 2dF Galaxy Redshift Survey: power-spectrum analysis of the final data set and cosmological implications (2005, background): “The northern supercluster is the heart of the structure that has also become known as the Sloan great wall (Gott et al. 2005).”
The Milky Way Tomography with SDSS. I. Stellar Number Density Distribution (2005, background): “This map projection does not preserve shapes (it is not conformal, e.g., Gott et al. 2005), but it preserves areas—the area of each pixel in the map is proportional to the solid angle on the sky, which makes it particularly suitable for study and comparison of counts and densities on the celestial…”
Tracing the cosmic web (2017, background): “Particularly outstanding specimens are the CfA Great Wall (Geller & Huchra 1989), the Sloan Great Wall (Gott et al. 2005), and most recently the BOSS Great Wall (Lietzen et al. 2016) and the well established supergalactic plane (de Vaucouleurs 1953; Lahav et al. 2000).”
Galaxy groups and clouds in the local (z∼ 0.01) Universe (2010, background): “The largest structure in the Universe detected to date is the Sloan Great Wall, filamentary aggregation of galaxies of 450 Mpc long, at distance of 310 Mpc (Gott et al. 2005).”
UniverseMachine: The correlation between galaxy growth and dark matter halo assembly from z = 0−10 (2018, methodology): “Table C5 lists the redshift and stellar mass bins we use for measuring CFs. Redshift bin constraints arise from volume completeness requirements, SDSS Great Wall avoidance (0.07 < z < 0.09; Gott et al. 2005), and a 1−2σ clustering excess at z < 0.045.”
PRIMUS: CONSTRAINTS ON STAR FORMATION QUENCHING AND GALAXY MERGING, AND THE EVOLUTION OF THE STELLAR MASS FUNCTION FROM z = 0–1 (2013, background): “However, this area of the sky is now known to contain one of the largest structures ever mapped, the SDSS Great Wall at z = 0.078 (Gott et al. 2005).”
Multiscale phenomenology of the cosmic web (2010, background): “They include immense elongated and semi-planar patterns (Diaferio & Geller 1997; Tittley & Henriksen 2001; Stevens et al. 2004; Ebeling et al. 2004; Pimbblet et al. 2004; Pimbblet & Drinkwater 2004; Bharadwaj & Pandey 2004; Pimbblet 2005) and includes huge wall-like structures like the Coma Great Wa”
The Luminosity and Color Dependence of the Galaxy Correlation Function (2004, background): “This ‘‘Sloan Great Wall’’ at 200 , 0 is the largest structure detected in the SDSS to date, or, indeed, in any galaxy redshift survey (see Gott et al. 2005).”
Cosmological Constraints from a Combination of Galaxy Clustering and Lensing -- III. Application to SDSS Data (2012, background): “Interestingly, this bin covers the volume that encloses the Sloan Great Wall (SGW), a huge supercluster at z ∼ 0.08 and the largest coherent structure detected in the SDSS (Gott et al. 2005).”
The WiggleZ Dark Energy Survey: the transition to large-scale cosmic homogeneity (2012, background): “The largest observed structure in the Universe, the Sloan Great Wall, is 320 h−1 Mpc long (Gott et al. 2005), appears inconsistent with the existence of a homogeneity scale below 100 h−1Mpc.”
Percolation Galaxy Groups and Clusters in the SDSS Redshift Survey: Identification, Catalogs, and the Multiplicity Function (2006, background): “Prominent in this projection of the data is the the giant supercluster at z ∼ 0.08 at the left end of the Sloan Great Wall of Galaxies, which extends from longitude 132 degrees (at z ∼ 0.05) to longitude 210 degrees (at z ∼ 0.08) (See Gott et al. 2005).”
