Astronomers have studied the role of an excited black hole in the death of an exotic ‘jellyfish’ galaxy. The supermassive black hole at the center of jellyfish galaxy JO201 is stripping away gas and throwing it out into space, accelerating suppression of star formation and effectively ‘killing’ the galaxy.
Jellyfish galaxies are spectacular objects that undergo a dramatic process of transformation as they plunge through the dense core of a galaxy cluster at supersonic speeds. External drag forces tear away the galaxy’s gas, in a process known as ram-pressure stripping, leaving extended tentacles of trailing material.
The fate of JO201 has been revealed as part of a study of 114 jellyfish galaxies by th...
