NGC 1532

NGC 1532, also known as Haley's Coronet, is an edge-on barred spiral galaxy located approximately 58 million light-years from the Solar System in the constellation Eridanus. The galaxy was discovered by James Dunlop on 29 October 1826.

Bar

NGC 1532 is one of many edge-on spiral galaxies that possesses a box-shaped bulge. This is an indication that the bulge is actually a bar. Such bars are easy to detect in face-on galaxies, where the structures can be identified visually. In inclined galaxies such as this one, however, careful analyses are needed to distinguish between bulges and bar structures.

Companion galaxies and interactions

NGC 1532 may possess several dwarf companion galaxies. The galaxy is clearly interacting with one of these galaxies, the amorphous dwarf galaxy NGC 1531. The tidal forces from this interaction have created unusual plumes above the disk of NGC 1532.
NGC 1532 is also an outlying member of the Fornax Cluster.

Supernovae

Three supernovae have been observed in NGC 1532:

SN 1981A was discovered by Robert Evans on 24 February 1981.
SN 2016iae was discovered by ATLAS on 7 November 2016.
SN 2016ija was discovered by the Distance Less Than 40 Mpc Survey on 22 November 2016.
