A void galaxy is a galaxy located in a cosmological void. Few galaxies exist in voids; most are located in sheets, walls and filaments that surround voids and supervoids.Astronomy and Astrophysics, "Results of a search for faint galaxies in voids", Kuhn, B.; Hopp, U.; Elsaesser, H.;, 'v.318', ''02/1997'', Many void galaxies are connected 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."Studies of Selected Voids. Faint Galaxies in the Direction of the Void 0049+05", G.T. Petrov, L. Slavcheva-Mihova, V. Kopchev, ''2007' ' 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.arXiv, "Cosmic Voids: structure, dynamics and galaxies", Rien van de Weygaert, Erwin Platen, ''16 Dec 2009'', ,

Formation

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 A supercluster is a large group of smaller galaxy clusters or galaxy groups; they are among the largest known structures in the universe. The Milky Way is part of the Local Group galaxy group (which contains more than 54 galaxies), which in turn ...

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 events such as these.
