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]

Messier 61 is an intermediate barred spiral galaxy in the Virgo Cluster of galaxies. It was first discovered by Barnaba Oriani on May 5, 1779, six days before Charles Messier discovered the same galaxy. Messier had observed it on the same night as Oriani but had mistaken it for a comet. Its distance has been estimated to be 45.61 million light years from the Milky Way Galaxy. It is a member of the M61 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.

Messier 66 or M66, also known as NGC 3627, is an intermediate spiral galaxy in the southern, equatorial half of Leo. It was discovered by French astronomer Charles Messier on 1 March 1780, who described it as "very long and very faint". This galaxy is a member of a small group of galaxies that includes M65 and NGC 3628, known as the Leo Triplet or the M66 Group. M65 and M66 are a common object for amateur astronomic observation, being separated by only 20′.

Arp 271 is a pair of similarly sized interacting spiral galaxies, NGC 5426 and NGC 5427, in the constellation of Virgo. It is not certain whether the galaxies are going to eventually collide or not. They will continue interacting for tens of millions of years, creating new stars as a result of the mutual gravitational attraction between the galaxies, a pull seen in the bridge of stars already connecting the two. Located about 130 million light-years away, the Arp 271 pair is about 130,000 light-years across. It was originally discovered in 1785 by William Herschel. It is speculated, that the Milky Way will undergo a similar collision in about five billion years with the neighbouring Andromeda Galaxy, which is currently located about 2.6 million light-years away.
