The new frontiers of gravitational microlensing
International Journal of Modern Physics D, 2022Albert Einstein referred to gravitational microlensing as a “most curious effect”, and while its underlying principles are intriguingly simple, their universality makes a powerful tool for inferring information about a wide range of astronomical bodies.

Quasar Variability and Gravitational Microlensing
The Astrophysical Journal, 1997In this Letter we examine the claim by Baganoff & Malkan that the timescale of brightness variations of quasars increases with decreasing optical wavelength, and that this effect can offset a time dilation effect at high redshift. They base their case on a thin accretion disk model that implies that timescales become shorter as the observed passband ...

Exoplanet searches with gravitational microlensing
2010Different regimes of gravitational lensing depend on lens masses and roughly correspond to angular distance between images. If a gravitational lens has a typical stellar mass, this regime is named microlensing because the typical angular distance between images is about microarcseconds in the case for sources and lenses at cosmological distances.

Chapter 3 presents the implementation of the computer model. Modelling techniques used by other researchers are discussed, as are alternative approaches considered for the implementation of this model. In order to simulate the evolving distribution of the lensing objects over time, the simulation was designed to run on high performance parallel ...

Morse theory and gravitational microlensing
Journal of Mathematical Physics, 1992Morse theory is used to rigorously obtain counting formulas and lower bounds for the total number of images of a background point source, not on a caustic, undergoing lensing by a single-plane microlens system having compact bodies plus either subcritical or supercritical continuously distributed matter.
