Void galaxy

Void galaxies are galaxies which exist in cosmological voids. Few galaxies exist in voids; most galaxies exist in sheets, walls and filaments that surround voids and supervoids. Many of the void galaxies are connected to each other through void filaments or tendrils, lightweight versions of the regular galaxy filaments that surround voids. These filaments are often straighter than their regular counterparts due to the lack of influence by surrounding filaments. These filaments can even be rich enough to form poor groups of galaxies. 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.
