NGC 1448 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 British astronomer John Herschel on 24 October 1835. Herschel observed the galaxy again on 14 December 1835, resulting in it being listed twice in the New General Catalogue, as NGC 1448 and as NGC 1457.
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.
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.Two monster black holes found lurking in nearby galaxies
Galaxy Group The galaxy belongs to the NGC 1433 group, part of the Doradus cloud of galaxies.
NGC 1448 is considered to be part of a galaxy group known as LGG 102. It has at least 5 members, which are NGC 1411, PGC 13390, PGC 13409 and IC 1970.
