NGC 1325 is a flocculent spiral galaxy situated in the constellation of Eridanus. Located about 75 million light years away, [2] it is a member of the Eridanus cluster of galaxies, [3] a cluster of about 200 galaxies. It was discovered by William Herschel on 19 December 1799.
NGC 1325 has a Hubble classification of SBbc, which indicates it is a barred spiral galaxy with moderately wound arms. [5] Its angular size on the night sky is 4.5' x 1.7'. [5] The disk of the galaxy is inclined at an angle of 71° with the main axis aligned along a position angle of 232°. [3] The rotation curve for the galaxy is flat across much of the radius from the core. [7] The galaxy is moving away from the Milky Way with a heliocentric radial velocity of 1,588 km/s. [2]
A supernova was discovered in this galaxy on December 30, 1975 by Justus Dunlap and Y. Dunlap at Corralitos Observatory. [8] Designated SN 1975S with a magnitude of 14.6, [9] it was positioned 53 ″ east and 77″ north of the galactic nucleus. The color of this supernova and the rapid decline of the lightcurve suggest it was a type II supernova. [10]
A core-collapse supernova designated SN 2021yja was detected in this galaxy on September 8, 2021. [11] It was initially categorized as a type II, but may instead be a type Ic. [12]
