NGC 1448

Galaxy in the constellation Horologium

NGC 1448 or NGC 1457 is an unbarred spiral galaxy seen nearly edge-on in the constellation Horologium. It is at a distance of 55 million light years from Earth. It was discovered by John Herschel in 1835.

From the spectral analysis of SN 2001el, over a dozen diffuse 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.[2]

In January 2017 it was announced that evidence for a supermassive black hole in NGC 1448 had been found in the center of the galaxy.[3]

The galaxy belongs to the NGC 1433 group,[4] part of the Doradus cloud of galaxies.

Supernovae

Six supernovae have been discovered in NGC 1448: SN 1983S (type II, mag. 14.5),[5] SN 2001el (type Ia, mag. 14.5),[6] SN 2003hn (type II, mag. 14.1),[7] SN 2014df (type Ib, mag. 14),[8] SN 2020zbv (type IIP, mag. 18.8),[9] and SN 2021pit (type Ia, mag. 12.3).[10]
