(Phys.org)--The spiral galaxy NGC 5523 is believed to be an example of an isolated galaxy whose evolution was not influenced by other objects. However, a new study conducted by U.S. astronomers shows that the isolation of NGC 5523 could be due to its past minor mergers with surrounding low-mass galaxies. The findings are detailed in a paper published Nov. 18 on arXiv.org.
