Massive Black Hole Growth and Formation
I review current difÞculties in understanding the origin of the supermassive black holes we now think reside in almost all normal to large galaxies. For example, it is not obvious how so much matter can be rapidly packed into such a small volume so as to produce the accreting supermassive black holes observed out to redshifts z > 6, when the Universe less than a tenth of its current age. I then...
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 کاملPrimordial Black Hole Formation from Inflaton
Measurements of the distances to SNe Ia have produced strong evidence that the Universe is really accelarating, implying the existence of a nearly uniform component of dark energy with the simplest explanation as a cosmological constant. In this paper a small changing cosmological term is proposed, which is a function of a slow-rolling scalar field, by which the de Sitter primordial black holes...
متن کاملPrimordial Black Hole Formation in Supergravity
We study a double inflation model (a preinflation + a new inflation) in supergravity and discuss the formation of primordial black holes which may be identified with massive compact halo objects (MACHOs) observed in the halo of our galaxy. The preinflation drives an inflaton for the new inflation close to the origin through supergravity effects and the new inflation naturally occurs. If the tot...
متن کاملImaging the Black Hole Silhouette of M87: Implications for Jet Formation and Black Hole Spin
The silhouette cast by the horizon of the supermassive black hole in M87 can now be resolved with the emerging millimeter very-long baseline interferometry (VLBI) capability. Despite being ∼ 2× 10 times farther away than Sgr A* (the supermassive black hole at the center of the Milky-Way and the primary target for horizon-scale imaging), M87’s much larger black hole mass results in a horizon ang...
