UGC 5460

UGC5460 is a barred spiral galaxy in the constellation of Ursa Major. Its velocity with respect to the cosmic microwave background for is , which corresponds to a Hubble distance of . In addition, two non redshift measurements give a distance of . The first known reference to this galaxy comes from Part 1 of the Morphological Catalogue of Galaxies, where it is listed as MCG +09-17-028.

The SIMBAD database lists UGC5460 as an active galaxy nucleus candidate, i.e. it has a compact region at the center that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.

NGC 3079 Group

UGC 5460 is a member of the NGC 3079 Group (also known as LGG 188), which contains six galaxies. The other five galaxies in the group are: NGC 3073, NGC 3079, UGC 5421, UGC 5459, and UGC 5479.

Supernovae

Two supernovae have been observed in UGC 5460:

• SN2011ht (TypeIIn, mag. 17) was discovered by Tom Boles on 29 September 2011. This supernova was initially suspected of being a luminous blue variable. Later analysis suggested that it belongs to an unusual group of SNe IIn, including SN 1994W and SN 2009kn, and perhaps SN 2005cl, that warrants a new designation of Type IIn-P.
• SN2015as (TypeIIb, mag. 16) was discovered by Ken'ichi Nishimura on 15 November 2015. Although initially classified as TypeII, later analysis concluded it to be TypeIIb.
