The cosmic timeline implied by the highest redshift quasars
Abstract The conventional picture of supermassive black-hole growth in the standard model had already been seriously challenged by the emergence of $$\sim 10^9\;M_\odot $$ ∼ 10 9 M ⊙ quasars at $$z\sim 7.5$$ z ∼ 7.5 , conflicting with the predicted formation of structure in the early $$\varLambda $$...
