NGC 3512 is an intermediate spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 1,677±21 km/s, which corresponds to a Hubble distance of 80.7 ± 5.7 Mly (24.73 ± 1.76 Mpc).[1] However, four non-redshift measurements give a farther mean distance of 113.50 ± 11.20 Mly (34.800 ± 3.434 Mpc).[2] It was discovered by German-British astronomer William Herschel on 11 April 1785.[3][4]
NGC 3512 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[1]
NGC 3504 group
[edit]NGC 3512 is a member of the NGC 3504 Group (also known as LGG 227), which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the western edge of the Virgo Supercluster.[5] There are eight other galaxies in the group, including NGC 3380, NGC 3400, NGC 3414, NGC 3451, NGC 3504, UGC 5921 and UGC 5958.[6][7] This NGC 3504 group is also mentioned by Abraham Mahtessian in his research paper published in 1998.[8]
Supernova
[edit]One supernova has been observed in NGC 3512:
- SN 2001fv (Type II, mag. 16.4) was discovered by British amateur astronomer Mark Armstrong on 3 November 2001.[9][10]
