List of voids

Add article description

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.

A map of galaxy voids

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.

Name	Coordinates	Distance	Diameter	Notes
Boötes Void (Great Void)	14^h 20^m 26°	150 Mpc	100 Mpc	The Hercules Supercluster separates the Northern Local Void from the Boötes Void.^[2] The Hercules Supercluster thus forms part of the near edge of the Boötes Void.^[8]
Canis Major Void
Columba Void
Coma Void				Discovered in 1975, along with the Coma Supercluster, it lies in front of the Coma Cluster.^[9] It was the first void to be discovered and is approximately 1/3 as far away as the much larger Boötes Void.^[10]
Corona Borealis Void
Eridanus Void				This void is separated from the Sculptor void by a sheet of galaxies.^[11]
Eridanus Supervoid (Great Void)	03^h 15^m 05^s −19° 35′ 02″	z=1	150 Mpc	The claimed Eridanus Supervoid or "Great Void", reported on 24 August 2007 by the NRAO from Very Large Array Sky Survey data.^[12] This void, if real, would be much larger than the others listed here (except the Giant Void), about 300 h⁻¹ Mpc in diameter and 1800–3000 h⁻¹ Mpc distant (where h is the dimensionless Hubble parameter). It would be associated with (and be the explanation of) a cold spot in the cosmic microwave background at the sky location. The evidence for such a "Great Void" is disputed by Smith and Huterer.^[13] They showed that the claims made of observational evidence for such a void from survey data neglected systematic effects and did not account for a posteriori choices made in analyzing data.
Southern Eridanus Void				The Southern Eridanus void is connected to the Eridanus void by a hole in the distribution of galaxies separating the two. A hole in the distribution of galaxies separating Sculptor and Southern Eridanus voids the size of (redshift) 1250 km/s appears to exist.^[11]
Fornax Void
Hercules Void	15.5^h +30°	cz=7000 km/s	3100 km/s	^[14] Discovered in 1979^[8]^[15]
Hydra Void				The Hydra Void lies beyond the Hydra–Centaurus Supercluster^[16]
Leo Void	11^h 30^m 0°	cz=4000 km/s		^[16]
Microscopium Void				A hole in the distribution of galaxies separating Sculptor and Microscopium voids the size of (redshift) 1250 km/s appears to exist. This is roughly 1/2 of Microscopium's diameter.^[11]
Ophiuchus Void	near 17^h −25°	< 5000 km/s (the outer limit)	perhaps 0–5000 km/s	25% of average universe density is the void density of matter. The far end of this void is defined by the Ophiuchus Supercluster.^[17]
Pegasus Void	22^h +15°	cz=5500 km/s	40 Mpc	^[18] The Perseus–Pisces Supercluster and Pegasus Supercluster form a sheet separate the Northern Local Void and Southern Local Void from the Pegasus Void.^[2]
Perseus–Pisces Void	1^h +10°	cz=8000 km/s	3000 km/s	Discovered in 1980,^[15] it is also called the Perseus Void
Sagittarius Void
Sculptor Void	23^h 48^m −24° 39′		34.8 Mpc/h	Corresponds to SRSS1 Void 3 and SRSS2 Void 5^[19] This void is separated from the Eridanus Void by a sheet of galaxies. A hole in the distribution of galaxies separating Sculptor and Southern Eridanus Voids the size of 1250 km/s appears to exist.^[11] The Sculptor Void lies next to the Southern Wall or Southern Great Wall.
Taurus Void			30 Mpc	The Taurus Void appears large and circular, and has walls of galaxies surrounding it. It lies next to the Perseus–Pisces Supercluster, and is the most visually identifiable. Several galaxies have been found to reside in the void, such as UGC 2627 and UGC 2629, both approximately 185 million light years away.^[20]

This is the diameter of the largest sphere one can describe inside the void that contains no superclusters. Some voids have an elongated shape, so this diameter may underrepresent the size of some voids.
