“Our work suggested that supermassive black holes are, on average, not as massive as previously thought.”
Another paper from the University of California Berkley, said: “The evidence for the unprecedentedly high mass of the unseen companion comes from reported radial velocity (RV) variability of the Hα [a spectral line packed with hydrogen electrons] emission line, which has been proposed to originate from an accretion disk around a BH.
“We show that there is in fact no evidence for RV variability of the Hα emission line, and that its apparent shifts instead originate from shifts in the luminous star’s Hα absorption line.”
Put simply, the University of California Berkley’s study states the Chinese Academy of Sciences research is wrong.
