NGC 5698 is a barred spiral galaxy in the constellation of Boötes. Its velocity with respect to the cosmic microwave background is 3,782±11 km/s, which corresponds to a Hubble distance of 181.9 ± 12.8 Mly (55.78 ± 3.91 Mpc).[1] However, 7 non-redshift measurements give a closer mean distance of 154.23 ± 11.53 Mly (47.286 ± 3.535 Mpc).[2] It was discovered by German-British astronomer William Herschel on 16 May 1787.[3]
NGC 5698 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.[4][5] Additionally, NGC 5698 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[6][5]
Supernova
One supernova has been observed in NGC 5698:
- SN 2005bc (Type Ia, mag. 16.6) was discovered by the Lick Observatory Supernova Search (LOSS), and independently by Tim Puckett and L. Cox, on 2 April 2005.[7][8]
