NGC 4580 is an unbarred spiral galaxy [2] located about 70 million light-years away [3] in the constellation Virgo. [4] NGC 4580 is also classified as a LINER galaxy. [3] [5] It was discovered by astronomer William Herschel on February 2, 1786 [6] and is a member of the Virgo Cluster. [2] [7]
Physical characteristics
NGC 4580 consists of a ringed structure. The inner pseudoring of the galaxy is very well-defined and is made of two tightly wound spiral arms. Three very diffuse spiral arms which are partly defined by dust, split off from the inner pseudoring. [2]
Truncated disk
NGC 4580 has a severely truncated star-forming disk. This may be due to ram-pressure stripping [2] caused by the infall of the Messier 49 subcluster into the Virgo Cluster. [8] Due to the truncation of the star forming disk, NGC 4580 is classified as an anemic galaxy. [9]
