Statistics of Gravitational Microlensing Magnification. II. Three-Dimensional Lens Distribution
Man Hoi Lee, Arif Babul, Lev Kofman +1
In Paper I we studied the theory of gravitational microlensing for a planar distribution of point masses. In this second paper, we extend the analysis to a three-dimensional lens d…
Statistics of Gravitational Microlensing Magnification. I. Two-Dimensional Lens Distribution
Lev Kofman, Nick Kaiser, Man Hoi Lee +1
(Abridged) In this paper we refine the theory of microlensing for a planar distribution of point masses. We derive the macroimage magnification distribution P(A) at high magnificat…
Comments on "Analytic and Numerical Study of Preheating Dynamics"
Lev Kofman, Andrei Linde, Alexei Starobinsky
In a recent paper Boyanovsky et al (hep-ph/9608205) studied preheating for a particular theory of the inflaton field. Although they results essentially confirm those of the origina…
The Origin of Matter in the Universe: Reheating after Inflation
Lev Kofman
In the inflationary scenario all the matter constituting the universe was created from the process of reheating after inflation. Recent development of the theory of reheating is br…
