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

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.

NGC 6240, also known as the Starfish Galaxy, is a nearby ultraluminous infrared galaxy (ULIRG) in the constellation Ophiuchus. It was discovered by French astronomer Édouard Stephan on 12 July 1871.

Luminous infrared galaxies or LIRGs are galaxies with luminosities, the measurement of brightness, above 1011 L☉. They are also referred to as submillimeter galaxies (SMGs) through their normal method of detection. LIRGs are more abundant than starburst galaxies, Seyfert galaxies and quasi-stellar objects at comparable luminosity. Infrared galaxies emit more energy in the infrared than at all other wavelengths combined. A LIRG's luminosity is 100 billion times that of the Sun.

APM 08279+5255 is a very distant, broad absorption line quasar located in the constellation Lynx. It is magnified and split into multiple images by the gravitational lensing effect of a foreground galaxy through which its light passes. It appears to be a giant elliptical galaxy with a supermassive black hole and associated accretion disk. It possesses large regions of hot dust and molecular gas, as well as regions with starburst activity.

<span class="mw-page-title-main">FSC 15307+3253</span> Galaxy in the constellation Corona Borealis

FSC15307+3253 is an ultraluminous infrared galaxy (ULIRG), with a luminosity between 8 and 1000 μm of approximately 2×1013L⊙, possibly the highest currently known. The "FSC" refers to Faint Source Catalogue, one of the source catalogs produced by the IRAS infrared survey mission. The emission is believed due to some combination of starburst activity and accretion onto a super-massive black hole, producing primary radiation at shorter wavelengths which is mostly blocked by obscuring dust, which is in turn heated and re-radiates in the infrared. The redshift of the source is z = 0.93, indicating a distance of the order of 7 billion light years.

NGC 3256 is a peculiar galaxy formed from the collision of two separate galaxies in the constellation of Vela. NGC 3256 is located about 100 million light-years away and belongs to the Hydra–Centaurus Supercluster complex. NGC 3256 provides a nearby template for studying the properties of young star clusters in tidal tails. The system hides a double nucleus and a tangle of dust lanes in the central region. The telltale signs of the collision are two extended luminous tails swirling out from the galaxy. The tails are studded with a particularly high density of star clusters. NGC 3256 is the most luminous galaxy in the infrared spectrum located within z 0.01 from Earth.

MCG -03-04-014 or PGC 4167, is a spiral galaxy located 450 million light-years in the constellation of Cetus. MCG -03-04-014 is classified as a luminous infrared galaxy, meaning it has high star-formation regions. MCG -03-04-014 has a galactic center that is obscured by dust lanes and presents an abundant supply of molecular gas. The reasons behind the luminosity of this galaxy are debated among astronomers. Some attribute it to recent starbursts, while others point to activity in the galaxies' supermassive black holes. It is also considered that both factors may contribute. The exact cause remains uncertain.
