NGC 1493

NGC1493 is a barred spiral galaxy in the constellation of Horologium. Its velocity with respect to the cosmic microwave background is 1004 ± 4km/s, which corresponds to a Hubble distance of. In addition, six non redshift measurements give a closer distance of. The galaxy was discovered by Scottish astronomer James Dunlop on 2 September 1826.
The SIMBAD database lists NGC1493 as a Seyfert II Galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.

Morphology

Eskridge, Frogel, and Pogge published a paper in 2002 describing the morphology of 205 closely spaced spiral or lenticular galaxies. The observations were made in the H-band of the infrared and in the B-band. Eskridge and colleagues described NGC 1493 as a:

NGC 1493 group

According to A.M. Garcia, NGC 1493 is the namesake of the NGC 1493 galaxy group. This group contains six galaxies, including IC 2000, NGC 1483, NGC 1494, PGC 13979, and PGC 14125.

Supernova

One supernova has been observed in NGC 1493. SN 2024abfo was discovered by ATLAS on 15 November 2024.
