NGC 1106 is a lenticular, non-barred spiral galaxy with considerable structure (type SA0^+), located in the Perseus constellation.[1][2] It was discovered by astronomer John Herschel on 18 September 1828.[3]
Characteristics
[edit | edit source]In 2016, astronomers confirmed NGC 1106 contains a Compton-thick[4] active galactic nucleus, after extensive analysis of the galaxy's X-ray spectra.[5] Due to the AGN in its center, it's also classified as a type II Seyfert galaxy, meaning it has the characteristic bright core of a Seyfert galaxy, as well as appearing bright when viewed at infrared wavelengths.
Star formation
[edit | edit source]A study released in 2022 detected active star formation in NGC 1106.[6] The research involved the use of far-ultraviolet and mid-infrared analysis, both techniques are extensively used as star formation rate tracers.[7]
NGC 1086 Group
[edit | edit source]NGC 1106 is a member of the NGC 1086 Group (also known as LGG 78). The other three galaxies are: NGC 1086, UGC 2349, and UGC 2350.[8]
