NGC 1407 is an elliptical galaxy in Eridanus. It is at a distance of 76 million light-years from Earth. It is the brightest galaxy in the NGC 1407 Group, part of the Eridanus Group, with NGC 1407 being its brightest member. [2] NGC 1400, the second-brightest of the group lies 11.8 arcmin away.

NGC 1407 is X-ray luminous, with high hot gas Fe abundance, [3] and with evidence of recurrent radio outbursts. [4] In the central area of the galaxy are present old stars, with mean age 12.0 ± 1.1 Gyrs, that are metal rich and with supersolar abundances of α-elements. Observations indicate that NGC 1407 hasn't recently undergone strong star-formation activity. [5] The galaxy hosts a supermassive black hole with a mass 1.12 ± 0.42 billion solar masses, based on velocity dispersion. [6]

The galaxy was discovered by 6 October 1785 by William Herschel. [7]

NGC 3621 is a field spiral galaxy about 22 Mly (6.7 Mpc) away in the equatorial constellation of Hydra. It is comparatively bright and can be well seen in moderate-sized telescopes. The galaxy is around 93,000 ly (29,000 pc) across and is inclined at an angle of 66° from being viewed face on. It shines with a luminosity equal to 13 billion times that of the Sun. The morphological classification is SA(s)d, which indicates this is an ordinary spiral with loosely wound arms. There is no evidence for a bulge. Although it appears to be isolated, NGC 3621 belongs to the Leo spur.

NGC 3783 is a barred spiral galaxy located about 135 million light years away in the constellation Centaurus. It is inclined by an angle of 23° to the line of sight from the Earth along a position angle of about 163°. The morphological classification of SBa indicates a bar structure across the center (B) and tightly-wound spiral arms (a). Although not shown by this classification, observers note the galaxy has a luminous inner ring surrounding the bar structure. The bright compact nucleus is active and categorized as a Seyfert 1 type. This nucleus is a strong source of X-ray emission and undergoes variations in emission across the electromagnetic spectrum.
