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]
