galaxy filament
(filament, galactic filament)
(thread-like formations of galaxies, 50 to 80 megaparsecs)
A galaxy filament is a very large region of many
galaxies in a thread-like formation,
portions of the formation being superclusters.
They are the largest structures identified and were first
determined to exist in the 1980s.
Supercluster complexes, galaxy sheets (aka galactic sheets), and
galaxy walls are particular kinds of filament.
Filaments:
- Coma Filament
- Pisces-Pegasus Filament
- Ursa Major Filament
- Lynx-Ursa Major Filament
- z=2.38 Filament
Galaxy walls:
Supercluster complex:
The current model of the universe is galaxy clusters
interconnected with a web of walls and filaments which are gathered
around high density regions dark matter (the cosmic web).
Attempts are made to detect dark matter independently of
viewing the galaxies that suggest its presence
(i.e., otherwise-undetected dark matter filaments),
such as discovering gravitational lensing at a region theorized
to have dark matter that happens not to have formed galaxies.
