3C 305, also known as IC 1065, is a lenticular galaxy located in the constellation Draco.[3][1] The galaxy is located 577 million light-years away from Earth.[2] It has an active galactic nucleus and is classified as a Seyfert 2 galaxy.[1][2] This galaxy was discovered by American astronomer Lewis Swift on April 7, 1888.[4]
3C 305 is also a radio galaxy.[5][6] It shows an extended X-ray halo previously detected by Chandra X-ray and Very Large Array observations and hydrogen outflow with a jet power of ~1043 erg s−1.[7]
In additional, 3C 305 shows broad HI absorption levels, which researchers interpreted it as jet-cloud interaction.[8] There are also signs that 3C 305 might be involved in a recent merger process with another gas-rich galaxy.[9]
