Black hole demographics from TDE modeling

2 Black Hole Demographics : High Redshift QSOs

Active Galaxies and the Study of Black Hole Demographics

We discuss the critical importance of black hole mass indicators based on scaling relations in active galaxies. We highlight outstanding uncertainties in these methods and potential paths to substantial progress in the next decade. 1. BLACK HOLE DEMOGRAPHICS AND ACTIVE GALAXIES The most reliable measures of black hole (BH) mass are derived from spatially resolved dynamical tracers, the stars at...

Organizational 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...

Modeling Kicks from the Merger of Generic Black-hole Binaries

Recent numerical relativistic results demonstrate that the merger of comparable-mass spinning black holes has a maximum “recoil kick” of up to ∼ 4000 km s. However the scaling of these recoil velocities with mass ratio is poorly understood. We present new runs showing that the maximum possible kick parallel to the orbital axis does not scale as ∼ η (where η is the symmetric mass ratio), as prev...

Black 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...
