NGC 5322 is an elliptical galaxy located in the constellation Ursa Major. It is located at a distance of circa 80 million light years from Earth, which, given its apparent dimensions, means that NGC 5322 is about 140,000 light years across.[1] It was discovered by William Herschel on March 19, 1790.[2]
The galaxy has been found to possess an inner stellar disc and an edge-on nuclear dust disc across the centre, aligned along the major-axis of the galaxy. The stellar disk counter-rotates the galaxy with respect to the spheroid and is believed to be the remnant of a gas-rich satellite. The spheroid has a boxy shape. The galaxy also has an outer halo. In the centre of the galaxy is predicted to lie a supermassive black hole with mass 108.51 ±0.40 (129-813 million) M☉.[3] Observed in radio waves, NGC 5322 is a weak source and features two symmetric jets emanating from the galactic core[4] and having a linear length of 1.6 kpc. The two jets are nearly perpendicular to the major axis of the galaxy and the circumnuclear dust disk. NGC 5322 is thought to contain a low-luminosity active galactic nucleus (AGN), powered by the accretion of gaseous material. The AGN then creates the radio jets.[3]
