Article in this week's Nature - Observing Growing Black Holes

Dark Cosmology Centre Associate Professor, Marianne Vestergaard, is among an international team of researchers published this week in Nature with new findings, the result of observations of 21 quasars from distant galaxies. 

"It appears we have found what are likely primitive first-generation quasars, that are born in a dust-free medium shortly after Big Bang and are now seen at somewhat later stages of evolution. With these quasars showing both rapid growth in both the black hole and the amount of dust, we may have found the young galaxy systems we have long been looking for”, explains Marianne Vestergaard and adds that “it is fantastic that we are witnesses to this building up of black holes and the amount of heavier elements in the form of dust”.
