IC 2431 are a group of interacting galaxies in the constellation of Cancer. [1] [2] They are located 684 million light-years away from the Solar System [3] and were discovered on February 24, 1896, by Stephane Javelle. [4]

Characteristics

There are at least three galaxies involved in the gravitational interaction. They are IC 2431 NED01 (known as PGC 200245), [5] IC 2431 NED02 (known as NSA 135647) [6] and IC 2431 NED03 (known as PGC 200246). [7] Additionally, a fourth galaxy (PGC 200247) [8] might also be involved in the interaction. As they draw closer to each other, the forces are causing them to tear each other apart. [9] This is common in the universe and all large galaxies, including the Milky Way own their size to violent mergers. [9]

The galaxies are undergoing tumultuous mixture of star formation and tidal distortions which are caused by the interaction. [10] In the center, a thick cloud of dust is seen obscuring, which light from a background galaxy is piercing its outer extremities. [10] Also, they display a thermally-dominated X-ray emission which is much more in excess of expectations based on its own star formation rate. [11]

IC 2431 falls under the category of Markarian Galaxies as Mrk 1224, [3] in which its core shines bright in ultraviolet rays. It is possible that carbon monoxide might be present in the regions of the interacting galaxies, which can be determined by the fraction of interstellar gas and total mass in form of molecules. [12] Not to mention, IC 2431 possibly contains an active nucleus which produces ionized gas outflows. [13] [14]

NGC 4492 is a spiral galaxy located about 90 million light-years away in the constellation Virgo. NGC 4492 was discovered by astronomer William Herschel on December 28, 1785. It was rediscovered by astronomer Arnold Schwassmann on January 23, 1900, and was listed as IC 3438. NGC 4492 lies in the direction of the Virgo Cluster. However, it is not considered to be a member of that cluster.

IC 4271 is a spiral galaxy located some 800 million light-years away in the Canes Venatici constellation. It is 130,000 light-years in diameter. IC 4271 was first located on July 10, 1896, by Stephane Javelle, a French astronomer. It hosts a Seyfert type 2 nucleus, containing an acceleration disc around its supermassive black hole which releases large amounts of radiation, hence its bright appearance. IC 4271 appears to be interacting with its smaller neighboring galaxy, PGC 3096774.

IRAS 14348-1447 known as PGC 52270, are a pair of spiral galaxies located 1 billion light-years away in the constellation of Libra. The galaxy IRAS 14348-1447NE, is in the early process of merging with IRAS 14348-1447SW, causing gravity to pull stars from both galaxies and forming tidal tails. As the interaction takes place, molecular gas is swirled about and creating emission that is responsible for the galaxies' ultraluminous appearance.
