Self-Similar Solution of Hot Accretion Flows with Ordered Magnetic Field and Outflow
De-Fu Bu, Feng Yuan, Fu-Guo Xie
Observations and numerical magnetohydrodynamic (MHD) simulations indicate the existence of outflows and ordered large-scale magnetic fields in the inner region of hot accretion flo…
The Compact Structure of Radio-Loud Broad Absorption Line Quasars
Y. Liu, D. R. Jiang, T. G. Wang +1
We present the results of EVN+MERLIN VLBI polarization observations of 8 Broad Absorption Line (BAL) quasars at 1.6 GHz, including 4 LoBALs and 4 HiBALs with either steep or flat s…
The Influences of Outflow on the Dynamics of Inflow
Fu-Guo Xie, Feng Yuan
Both numerical simulations and observations indicate that in an advection-dominated accretion flow most of the accretion material supplied at the outer boundary will not reach the…
Global Compton heating and cooling in hot accretion flows
Feng Yuan, Fuguo Xie, Jeremiah P. Ostriker
The hot accretion flow is usually optically thin in the radial direction, therefore the photons produced at one radius can travel for a long distance without being absorbed. These…
