IC 4141 is a spiral galaxy in the constellation of Coma Berenices.[1] [2] The galaxy is located 900 million light-years away from Earth. Discovered in 1904 by German astronomer Max Wolf,[3] it measures 255,000 light-years across in diameter. With a radial velocity of 19,000 kilometers per second, it is slowly drifting from the Solar System.
__TOC__
The galaxy has been intensively studied by the Hubble telescope due to its distinctive spiral structures, which appears to be a result of gravitational interactions from nearby galaxies inside Abell 1668, thus distorting its appearance into a jellyfish galaxy.[4] In reality, it is actually caused by dynamic pressure. The dust and gas has been stripped from the galaxy itself caused by intracluster medium,[5] thus creating tendrils of long star formation trails. Due to its consistent ram pressure stripping, its star formation has decreased significantly over the last 10 years. Eventually, no new stars will be made.[6]
IC 4141 is classified as a LINER galaxy by the SIMBAD database, this indicates levels of emission spectrum, in which its supermassive black hole appears to be responsible for.[7]
