NGC 3672 is an unbarred spiral galaxy in the constellation Crater. The galaxy lies about 80 million light years away from Earth, which means, given its apparent dimensions, that NGC 3672 is approximately 100,000 light years across. [1] It was discovered by William Herschel on March 4, 1786. [3]

Characteristics

The galaxy has a small, bright nucleus. Its mass is estimated to be about 200 million solar masses and its radius 350 parsecs (1,100 ly). Spectral analysis of the nuclear region of the galaxy revealed the presence of large velocity gradients along the minor axis of the outer disk. This has been interpreted as a result of the presence of excited nuclear gas rotating at a large angle with respect to the rest of the galaxy or gas clouds collapsing towards the centre. [4] That was the first time such nuclear gas kinematics were observed in a spiral galaxy. [5] Four well defined arms with many knots emerge from the centre of the galaxy in a grand design pattern. [6] [7] The star formation rate of the galaxy is estimated to be about 3.5 M per year. [8]

Supernovae

Two supernovae have been observed in NGC 3672:

Nearby galaxies

NGC 3672 is the foremost member of the NGC 3672 Group, also known as LGG 235. [14] Other members of the group include NGC 3636, NGC 3637, [15] and IC 688. [14] IC 688 lies about 20 arcminutes away from NGC 3672. [7] The galaxy group lies in the same galaxy cloud with NGC 3730 and NGC 3779. [14]
