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[edit]
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]
