Abstract:The standard alpha-disc model predicts an anti-correlation between the density of the inner accretion disc and the black hole mass times square of the accretion rate, as seen in higher mass (M BH > 10 6 M ⊙ ) active galactic nuclei (AGNs). In this work, we test the predictions of the alpha-disc model and study the properties of the inner accretion flow for the low-mass end (M BH ≈ 10 5−6 M ⊙ ) of AGNs. We utilize a new high-density disc reflection model where the density parameter varies from n e = 10 15 to 10… Show more
