We estimated spin, inclination angle and corresponding SMBH mass values for sample of extremely distant (6 < z < 7.5) ultraluminous quasars. The estimated spin values are on average greater that 0.9 and the spin distribution has a characteristic appearance, similar to ones obtained for other types of AGNs and quasars. The dependence of estimated parameters on each other shows strong correlations between them, from which we can assume that in this early quasars the growth of SMBHs mass should occur mainly due to disk accretion with high accretion rate, which very effectively increases the spin.

  1. Estimation of black hole spins in low-mass AGNs and comparison with other types of AGNs

    astro-ph.HE 2026-06 unverdicted novelty 3.0

    Spins of low-mass AGN black holes decrease with mass, supporting mergers or chaotic accretion as growth mechanisms and suggesting an evolutionary sequence where spins first decrease then slowly increase.
