NGC 1320 is a spiral galaxy located in the constellation Eridanus. Its speed relative to the cosmic 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-British astronomer William Herschel in 1784.[2]
The luminosity class of NGC 1320 is I and it is an active Seyfert 2 galaxy. NGC 1320 is a galaxy whose core shines in the ultraviolet region. It is listed in the Markarian 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 the Hubble 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 ⊙. A study carried out in 2007 on 90 Seyfert 2 type galaxies using velocity 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 ⊙.[5] [6]
According to another study published in 2012 and based on the dispersion of the velocities of the central region of NGC 3982, the mass of the central black hole would be 19.5 million ⊙.[7]
The supernova SN 1994aa (type Ia, mag. 17)[8] was discovered in NGC 1320 on September 11, 1994, by the Scottish-Australian astronomer Robert H. McNaught.[9]
