IC 5337 or JW100, is a spiral galaxy located 800 million light-years away from the Solar System in the constellation of Pegasus.[1][2]
It was discovered by French astronomer, Stephane Javelle on November 25, 1897[3] and is probably gravitationally bound to IC 5338, the brightest cluster galaxy in Abell 2626. According to SIMBAD, IC 5337 is considered an emission-line galaxy.[4]
IC 5337 is a jellyfish galaxy, mainly due to ram pressure.[5][6][7] Star-forming gas are thrown about, as the galaxy penetrates through the thin gas layer and causing them to drip from the galaxy's disc, giving it its unique appearance of a cosmic jellyfish.[5] It has a stellar mass of 3.2 × 1011 M⊙[8] and contains an active galactic nucleus likely trigged by accretion of matter into its supermassive black hole.[9]
In addition, IC 5337 also shows an X-ray source.[10]
