MCG+01-02-015 is a spiral galaxy in the constellation Pisces. It is an example of a void galaxy.[4]
Observational History
MCG+01-02-015 was previously classified as an elliptical galaxy of class E2 although higher-resolution imaging has revealed it to be a barred spiral galaxy.[3]
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 MCG+01-02-015 are sometimes left behind from events such as these.[5]
Use in scientific study
MCG+01-02-015 is a time capsule of galactic evolution and offers an idea as to how these objects mature due to it not interacting with any neighbouring galaxies.
