IC 3222 known as PGC 40065 and UGC 7437, is a barred spiral galaxy with a ring structure [1] located in the constellation of Coma Berenices. [2] [3] It is located 869 million light-years from the Solar System [4] and has dimensions of 0.90 x 0.6 arcmin, [5] meaning IC 3222 is 235,000 light-years across in diameter. This makes it a large galaxy. IC 3222 was discovered by Max Wolf on March 23, 1903. [6]

Characteristics

IC 3222 has an active galactic nucleus. It is classified as a LINER galaxy. [7] [8] That is, a galaxy whose nucleus presents an emission spectrum which is characterized by broad lines of weakly ionized atoms. [4]

This activity might be attributed to a central mass-accreting supermassive black hole, making IC 3222 one of the galaxies with the largest AGN sub-population, which dominate in numbers over Seyfert galaxies and quasars. [9]

An active galactic nucleus (AGN) is 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. Such excess, non-stellar emissions have been observed in the radio, microwave, infrared, optical, ultra-violet, X-ray and gamma ray wavebands. A galaxy hosting an AGN is called an active galaxy. The non-stellar radiation from an AGN is theorized to result from the accretion of matter by a supermassive black hole at the center of its host galaxy.
