IC 4141is aspiral galaxyin the constellation ofComa Berenices.[2][1]The galaxy is located 900 millionlight-yearsaway fromEarth.Founded in 1904 byGermanastronomerMax 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 theSolar System.
Characteristics
[edit]The galaxy has been intensively studied by theHubble telescopedue to its distinctive spiral structures, which appears to be a result ofgravitational interactionsfrom nearby galaxies inside Abell 1668, thus distorting its appearance into ajellyfish galaxy.[4]In reality, it is actually caused by dynamicpressure.The dust and gas has been stripped from the galaxy itself caused byintracluster 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 aLINERgalaxy by theSIMBADdatabase, this indicates levels ofemission spectrum,in which itssupermassive black holeappears to be responsible for.[7]
