NGC 1320 is aspiral galaxy located in theconstellation Eridanus. Its speed relative to thecosmic microwave background is 2,620 ± 15 km/s, which corresponds to a Hubble distance of 38.6 ± 2.7 Mpc (~126 million ly).[1] It was discovered by the German-BritishastronomerWilliam Herschel in 1784.[2]
The luminosity class of NGC 1320 is I and it is an activeSeyfert 2 galaxy.[1] NGC 1320 is a galaxy whose core shines in the ultraviolet region. It is listed in theMarkarian catalog under the symbol Mrk 607 (MK 607).[3]
To date, a non-redshift-based measurement gives a distance of approximately 37,700 Mpc (~123 million ly).[4] This value is within theHubble distance values.
According to the authors of a paper published in 2002, the mass of the central black hole of NGC 1230 is 1.51 x 107 𝑀⊙. A study carried out in 2007 on 90 Seyfert 2 type galaxies usingvelocity dispersion made it possible to estimate the mass of their central supermassive black holes. For NGC 1320, the mass of the black hole is 15 ×106 𝑀⊙.[5][6]
According to another study published in 2012 and based on the dispersion of the velocities of the central region ofNGC 3982, the mass of the central black hole would be 19.5 million 𝑀⊙.[5][7]
Onesupernova has been observed in NGC 1320: SN 1994aa (type Ia, mag. 17) was discovered by the Scottish-Australian astronomerRobert H. McNaught on 11 September 1994.[8][9]
