UGC 5460 is a barred spiral galaxy in the constellation of Ursa Major. Its velocity with respect to the cosmic microwave background for is 1,276±14 km/s, which corresponds to a Hubble distance of 61.4 ± 4.4 Mly (18.82 ± 1.34 Mpc).[1] In addition, two non redshift measurements give a distance of 58.1 ± 6.8 Mly (17.8 ± 2.1 Mpc).[2] 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 UGC 5460 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.[3]
NGC 3079 Group
[edit | edit source]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.[4]
Supernovae
[edit | edit source]
Two supernovae have been observed in UGC 5460:
- SN 2011ht (Type IIn, mag. 17) was discovered by Tom Boles on 29 September 2011.[5][6] This supernova was initially suspected of being a luminous blue variable.[5] 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.[7]
- SN 2015as (Type IIb, mag. 16) was discovered by Ken'ichi Nishimura on 15 November 2015.[8] Although initially classified as Type II,[9] later analysis concluded it to be Type IIb.[10]
