RB 199

RB 199, also known as LEDA 126817 or GMP 4060, is an E+A galaxy in the Coma cluster.[1][2] [3]

Not to be confused with Turbo-Union RB199.

RB199 contains filamentary structures of hot gas known as "ram pressure fireballs". These fireballs are actively forming stars. After forming, the stars are no longer subjected to a ram pressure force, causing them to be left behind in a tail as the gas structure is accelerated.
