UGC 4798 is a spiral galaxy in the constellation of Lynx. Its velocity with respect to the cosmic microwave background is 8,209±14 km/s, which corresponds to a Hubble distance of 394.9 ± 27.7 Mly (121.07 ± 8.48 Mpc).[1]. The first known reference to this galaxy comes from Part 1 of the Morphological Catalogue of Galaxies, published in 1962, where it is listed as MCG +08-17-038.[2]
Supernovae
Five supernovae have been observed in UGC 4798:
- SN 2005mf (Type Ic, mag. 17.4) was discovered by the THCA Supernova Survey on 25 December 2005.[3][4]
- SN 2013V (Type Ia, mag. 17.8) was discovered by T. Crowley, Jack Newton, and Tim Puckett on 6 January 2013.[5][6]
