Void galaxy
Galaxy found in a cosmological void
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]
