2MASX J09133888-1019196 are a pair of interacting galaxies located in the constellation of Hydra.[1] It is located 735 million light-years from the solar system.[2]
Characteristics[edit]
2MASX J09133888-1019196 has a distorted appearance due to the gravity interactions and there is a gap distance of 130,000 light-years between the galaxies, meaning they are beginning to merge.[1] 2MASX J09133888-1019196 is considered as a luminous infrared galaxy[3] which is unusual for such early stages of interacting galaxies.[1][4] It is possibly powered by starbursts with high star formation rates, exceeding 100 M⊙ yr−1, that is combined with contribution from an active galactic nucleus.[5] It is also likely that one or both galaxies might have experienced merging or interacted in the past. Both galaxies have supermassive black holes lurking in their cores.[1] According to SIMBAD, 2MASX J09133888-1019196 is described as Seyfert 2 galaxy,[6] hence its reason for having high luminosity.
