Characteristics

NGC 1167 is a massive galaxy with a giant HI disk of DHI = 160 kpc. For comparison, the Milky Way galaxy is approximately 30.6 kpc across. Astronomers suggest NGC 1167 is accumulating gas by satellite accretion, incorporating its neighboring galaxies through fairly recent mergers, expanding its disk. [4] While this galaxy contains significant amount of gas, matter is distributed over a very large area, resulting in a relatively low surface density (less than 2 M⊙/pc). [5]

NGC 1167 has ring-like arcs where star formation is taking place. However its arcs are uncommonly thin and smooth, not showing the expected irregularities observed in star-forming regions of a galaxy's arms. Astronomers suggest this might be due to the lack of O stars within the structure. The nature of the phenomenon is yet not fully comprehended. [5]

Radio jet

In a research paper released in 2022, astronomers reported the detection of a radio jet (named B2 0258+35) on NGC 1167. Given the properties of the detected X-ray emission coming from the jet and its similarity with an extended emission from an active galactic nucleus, the researchers concluded the galaxy is presently a LINER but had an AGN in the past.

NGC 1672 is a barred spiral galaxy located in the constellation Dorado. It was discovered by the astronomer James Dunlop on November 5, 1826. It was originally unclear whether it was a member of the Dorado Group, with some sources finding it to be a member and other sources rejecting its membership. However, recent tip of the red-giant branch (TRGB) measurements indicate that NGC 1672 is located at the same distance as other members, suggesting it is indeed a member of the Dorado Group.
