The cosmic timeline implied by the highest redshift quasars
Published 2024-12-01“…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 $$\varLambda $$ Λ CDM Universe. …”

The quasars’ redshift estimation method based on piecewise Gaussian fitting
Published 2019-05-01“…To solve the problem that high-redshift and broad emission lines weaken the quasar discovery and observation severely, a new redshift calculation method based on piecewise Gaussian fitting is proposed. …”
