NGC 3748 is a lenticular galaxy with a bar [1] located in the Leo constellation. [2] [3] It is located 440 million light-years away from the Solar System [4] and was discovered by Ralph Copeland on April 5, 1874, but also observed by Hermann Kobold, Lawrence Parsons and John Louis Emil Dreyer. [5]
Like NGC 3746, NGC 3748 also has a recessed core (RET). [4] It is described as, "moderately bright, fairly small, slightly elongated NW-SE, 0.4'x0.3' with a small bright core". [6]
NGC 3748 is a member of the Copeland Septet which is made up of 7 galaxies which were discovered by Copeland in 1874. [7] The other members are NGC 3745, NGC 3746, NGC 3750, NGC 3751, NGC 3753 and NGC 3754. [8]
Halton Arp noticed the galaxies in this group in an article that was published in 1966. [9] This group is known as Arp 320 along with another galaxy, PGC 36010. [10]
This group was observed by Paul Hickson whom he included in his article in 1982. [11] The group is known as Hickson 57, in which NGC 3748 is designated as HCG 57E. [12]
