Primordial 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 کاملBlack Hole Formation from Massive Scalar Fields
It is shown that there exists a range of parameters in which gravitational collapse with a spherically symmetric massive scalar field can be treated as if it were collapsing dust. This implies a criterion for the formation of black holes depending on the size and mass of the initial field configuration and the mass of the scalar field.

متن کاملBlack hole formation from colliding bubbles
Some indication of conditions that are necessary for the formation of black holes from the collision of bubbles during a supercooled phase transition in the the early universe are explored. Two colliding bubbles can never form a black hole. Three colliding bubbles can refocus the energy in their walls to the extent that it becomes infinite. 98.80Cq, 04.60.+n, 97.60.Lf Typeset using REVTEX
متن کاملWhat Can We Learn about Black-hole Formation from Black-hole X-ray Binaries?
I discuss the effect of the formation of a black hole on a (close) binary and show some of the current constraints that the observed properties of black hole X-ray binaries put on the formation of black holes. In particular I discuss the evidence for and against asymmetric kicks imparted on the black hole at formation and find contradicting answers, as there seems to be evidence for kick for in...
متن کاملConstraints on mass ejection in black hole formation derived from black hole X-ray binaries
Both the recently observed high runaway velocities of Cyg X-1 (∼ 50 km s) and X-ray Nova Sco 1994 (≥ 100 km s) and the relatively low radial velocities of the black hole X-ray binaries with low mass donor stars, can be explained by symmetric mass ejection in the supernovae (SNe) which formed the black holes in these systems. Assuming symmetric mass ejection in black hole formation, we estimate ...
