Void galaxy

A void galaxy is a galaxy located in a cosmological void.[1] Few galaxies exist in voids; most are located in sheets, walls and filaments that surround voids and supervoids.[2][3] Many void galaxies are connected through void filaments[4] or tendrils,[5] less massive versions of the regular galaxy filaments that surround voids. These filaments are often straighter than their non-void counterparts due to the lack of influence by surrounding filaments.[4] These filaments can even be rich enough to form poor galaxy clusters.[6] The void galaxies themselves are thought to represent pristine examples of galactic evolution, having few neighbours, and likely to have formed from pure intergalactic gas.[7]

Formation

[edit]

It is theorised by many astrophysicists that void galaxies are the result of large galactic filaments being pulled by the gravity of a major super cluster out of the less densely populated areas, causing voids such as the Boötes Void to grow. Galaxies such as MCG+01-02-015 are sometimes left behind from such events.[8]
