Black Hole Winds
We show that black holes accreting at or above the Eddington rate probably produce winds which are optically thick in the continuum, whether in quasars or X–ray bina-ries. The photospheric radius and outflow speed are proportional to ˙ M 2 out and ˙ M −1 out respectively, where ˙ M out is the mass outflow rate. The outflow momentum rate is always of order L Edd /c. Blackbody emission from these...
متن کاملContinuum Acceleration of Black Hole Winds
Motivated by recent observations of high-velocity, highly ionized winds in several QSOs, models of purely continuum-driven winds launched from ∼ 200 GMBH/c2 are presented. Launching conditions are investigated, as well as the observational signatures for a variety of initial conditions and illuminating continua. While we verify that continuum-driven, highly-ionized outflows reach the observed v...
متن کاملOrganizational Black Hole Theory
There are issues in organizations that require new theoretical formulation. Hence, metaphorical theorizing is used in the study of organizations to interpret them and understand their complexities. In this method, the organization is likened to an entity and one of the key features of that entity is generalized to the organization. It should be borne in mind that most organizational theories ar...
متن کاملBlack Hole thermodynamics without a black hole?
In the present paper we consider, using our earlier results, the process of quantum gravitational collapse and argue that there exists the final quantum state when the collapse stops. This state, which can be called the “no-memory state”, reminds the final “no-hair state” of the classical gravitational collapse. Translating the “no-memory state” into classical language we construct the classica...
متن کاملSolutions of Two Dimensional Viscous Accretion and Winds In Kerr Black Hole Geometry
We extend our previous studies of shock waves and shock-free solutions in thin accretion and winds in pseudo-Newtonian geometry to the case when the flow is two-dimensional and around a Kerr black hole. We present equations for fully general relativistic viscous transonic flows and classify the parameter space according to whether or not shocks form in an inviscid flow. We discuss the behaviors...
