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]
  • PSN J09084248+4448132 (Type Ia, mag. 15.8) was discovered by the Catalina Real-time Transient Survey and Stan Howerton on 26 October 2014.[7][8]
  • SN 2019cad (Type Ic, mag. 18.75) was discovered by the Zwicky Transient Facility on 17 March 2019.[9] This supernova was double-peaked and resembled SN 2005bf.[10]
  • SN 2025ane (Type II, mag. 18.2563) was discovered by the Zwicky Transient Facility on 31 January 2025.[11]
