List of voids
This is a list of voids in astronomy. Voids are particularly galaxy-poor regions of space between filaments, making up the large-scale structure of the universe. Some voids are known as supervoids.
In the tables, z is the cosmological redshift, c the speed of light, and h the dimensionless Hubble parameter, which has a value of approximately 0.7 (the Hubble constant H0 = h × 100 km s−1 Mpc−1). Mpc stands for megaparsec.
The co-ordinates (right ascension and declination) and distance given refer to the approximate center of the region.
In 1985, Tully determined a local dominant supercluster plane, and found the Pisces–Cetus Supercluster Complex.
In a 1985 study of Abell clusters, 29 voids were determined, in the sphere z<0.1 around Earth.
A redshift survey of galaxies in the southern sky in 1988, out to a distance of 120 Mpc/h, revealed some voids.
In 1994, a redshift survey in the southern sky identified 18 voids, 11 of which are major voids.
A 1994 census lists a total of 27 supervoids within a cube of 740 Mpc a side, centered on us (z=0.1 distant sphere).
