NGC 1448 is anunbarred spiral galaxy seen nearly edge-on in the constellationHorologium. It is at a distance of 55 millionlight years from Earth. It was discovered by British astronomerJohn Herschel on 24 October 1835.[2] Herschel observed the galaxy again on 14 December 1835, resulting in it being listed twice in theNew General Catalogue, as NGC 1448 and as NGC 1457.[2]

From the spectral analysis of SN 2001el, over a dozendiffuse interstellar bands were discovered in NGC 1448 – one of the few cases that these bands were observed outside of the Milky Way. However, the bands were significantly weaker at SN 2003hn.[3]

In January 2017 it was announced that evidence for asupermassive black hole in NGC 1448 had been found in the center of the galaxy.[4]

The galaxy belongs to theNGC 1433 group,[5] part of the Doradus cloud of galaxies.

Supernovae

[edit]

Sixsupernovae have been observed in NGC 1448:

  • SN 1983S (Type II, mag. 14.5) was discovered byRobert Evans on 6 October 1983.[6][7]
  • SN 2001el (Type Ia, mag. 14.5) was discovered byBerto Monard on 17 September 2001.[8][9] It reached magnitude 12.3, making it the brightest supernova of 2001.[10]
  • SN 2003hn (Type II, mag. 14.1) was discovered by Robert Evans on 25 August 2003.[11][12]
  • SN 2014df (Type Ib, mag. 14) was discovered by Berto Monard on 3 June 2014.[13][14]
  • SN 2020zbv (Type IIP, mag. 18.83) was discovered by theDistance Less Than 40 Mpc Survey (DLT40) on 10 November 2020.[15]
  • SN 2021pit (Type Ia, mag. 13.5) was discovered byASAS-SN on 10 June 2021.[16]
