New observations challenge evidence for an 'outsize' black hole in the early universe‎

A recent reanalysis of the outsize black hole galaxy UHZ1 using existing X-ray data and new infrared observations challenges a previous groundbreaking claim. Three years ago, this galaxy made news for hosting an unusually massive and heavily dust-obscured black hole formed through direct collapse. Led by Fan Zou of the University of Michigan, the new study reports no signs of hidden black hole activity. The paper, published in The Astrophysical Journal on Oct. 14, suggests UHZ1 could be a low-mass, metal-poor, star-forming galaxy.
