NGC 6045

NGC 6045 is a barred spiral galaxy located about 450 million light-years away^[2] in the constellation Hercules.^[3] NGC 6045 was discovered by astronomer Lewis Swift on June 27, 1886^[4] and is a member of the Hercules Cluster.^[5][4] It is also a LINER galaxy.^[6]

Possible interaction

NGC 6045 is very luminous in both X-ray^[5] and infrared light.^[7] This high luminosity in both X-ray and infrared has been suggested to be the result of a starburst event in the galaxy.^[5][7] It is thought that starburst events are caused by interactions or mergers with other galaxies.^[8][5] Also, NGC 6045 has a warped disk which may be due to an interaction^[7] with the elliptical galaxy NGC 6047 which lies around ~320,000 ly (97 kpc) from the galaxy.^[5]
