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.

Contents

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]

Messier 83 or M83, also known as the Southern Pinwheel Galaxy and NGC 5236, is a barred spiral galaxy approximately 15 million light-years away in the constellation borders of Hydra and Centaurus. Nicolas-Louis de Lacaille discovered M83 on 17 February 1752 at the Cape of Good Hope. Charles Messier added it to his catalogue of nebulous objects in March 1781.

Messier 84 or M84, also known as NGC 4374, is a giant elliptical or lenticular galaxy in the constellation Virgo. Charles Messier discovered the object in 1781 in a systematic search for "nebulous objects" in the night sky. It is the 84th object in the Messier Catalogue and in the heavily populated core of the Virgo Cluster of galaxies, part of the local supercluster.

NGC 514 is a low-luminosity, intermediate spiral galaxy in the equatorial constellation of Pisces, located at a distance of approximately 83 million light-years from the Milky Way. It was discovered on 16 October 1784 by astronomer William Herschel. The general form of the galaxy is specified by its morphological classification of SAB(rs)c, which indicates it has a weak bar system at the core (SAB), an incomplete ring formation around the bar (rs), and somewhat loosely-wound spiral arms (c). This galaxy has an H II nucleus with an extended region that displays weak emission lines in the optical range, but not in the near infrared. The suspected supermassive black hole at the core has an estimated mass of 3.2×106 M☉.
