Markarian 1034 (Mrk 1034) is a pair of spiral galaxies comprising PGC 9074 and PGC 9071, located in the constellation Triangulum. They are located at a distance of 465 million light-years from Earth and are classified as luminous infrared galaxies.[1][2][3]
PGC 9074
[edit]PGC 9074 known as Mrk 1034a,[4] is classified as a type Sa galaxy.[5] It has two spiral arms around its nucleus with a bright galactic bulge. These spiral arms are shown to have dust obscuring background light of stars behind its regions. These are mixed together with star clusters containing a stellar population of hot, recently formed stars. In the central region of PGC 9074, older stars are found surrounded by a faint halo of another group of old stars, some inside globular clusters.[6]
The nucleus of PGC 9074 is active and it has been classified as a Seyfert 1 galaxy.[7][8] It is categorized as a Markarian galaxy because when, compared to other galaxies, its nucleus emits large amounts of ultraviolet rays.[9] It is on the verge of gravitationally interacting with its neighbor, PGC 9071 since the two of them are at close proximity.[6]
PGC 9071
[edit]PGC 9071 known as Mrk 1034b,[10] is classified as a type Sb galaxy.[5] It has almost the same appearance and size to PGC 9074, but with a fainter bulge and a slight altered spiral arm structure: its coils are further away. In addition, it contains a young stellar popular of hot stars combined with obscured dust, with a central region of older star populations.[6]
The nucleus of PGC 9071 is active and it is also a Seyfert 1 galaxy.[9][8] It has a high surface brightness[11] and contains a one-sided jet measured to be 0.144 arcsecs or 103 pc, with a 'kidney-bean' shaped structure located within its optical core.[12] The galaxy is also interacting with PGC 9074, in which eventually they will merge together to form a larger entity in hundreds of millions of years.[6]
