Void galaxy

Last updated

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

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 the spiral galaxy MCG+01-02-015 are sometimes left behind from such events. [8]
