WebJan 1, 2024 · In the conventional δ -Eddington approximation, f is set to g2, which is a measure of the variance of the phase function. As already reported by a previous study [15], the conventional approach ( f = g2) shows accurate results for optically thick clouds ( τ ≥ 5). However, for the optically thin clouds ( τ < 5), single scattering becomes ... WebAug 21, 2024 · We perform non-hydrodynamical 2.5D simulations to study the dynamics of material above accretion disk based on the disk radiation pressure acting on dust. We assume a super-accreting underlying disk with the accretion rate of 10 times the Eddington rate with central black hole mass ranging from 107 up to 109M⊙. Such high accretion …
Radiative transfer with delta-Eddington-type phase functions
WebWe present a generalized Delta-Eddington phase function to simplify the radiative transfer equation to integral equations with respect to both photon fluence rate and flux vector. The photon fluence rate and flux can be solved from the system of integral equations. By comparing to the Monte Carlo simulation results, the solutions of the system ... WebApproximations for Spherical Harmonics Radiative Transfer in Reflected Light¶. In Rooney et al 2024 we rigorously derive the spherical harmonics method for reflected light and benchmark the 4-term method (SH4) against Toon et al. 1989 and two independent methods. Here, we provide the code to reproduce the analysis that compares Toon89 … boy scouts of america oklahoma

WebMay 1, 2024 · Here, we choose the anisotropy factor g = 0.9, and take the parameters as p 0 = 0.85 and g ′ = 0.12 in the delta-Eddington phase function. Based on the delta … Webgrowth factor expected in sub-Eddington phase is only 2. Therefore, the cosmic BH growth by accretion is likely dominated by super-Eddington phase, rather than sub-Eddington phase which is the majority among AGNs. This analysis is based on the fraction and the average accretion rate of NLS1s and NLQs obtained for z 0.5. If those numbers Web1%–10% of the mass accreted in the super-Eddington phase. The temporal evolution of the radio emission also uncovers the circumnuclear density profile,r()RRµ-2.5 on a scale of about 0.01pc, a scale that cannot be probed via direct measurements even in the nearest supermassive black holes.
