The cosmic timeline implied by the highest redshift quasars by Fulvio Melia

“…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 impact of compact object deformation on thin accretion disk properties by Shokoufe Faraji

“…The main purpose of this work is to determine whether such a deformed object possesses its own observational fingerprint that can distinguish it from Schwarzschild and Kerr black holes. Our analysis reveals the properties of this relativistic accretion disk model and its dependence on the initial parameters.…”
