Quasar Variability and Gravitational Microlensing

The Astrophysical Journal, 1997
In 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 Search Via Gravitational Microlensing

AIP Conference Proceedings, 2009
We review the recent results of the exoplanet search via gravitational microlensing. The microlensing technique is unique and complementary to other methods because it does not rely on the light from the primary. Microlensing is sensitive to small‐size planets down to those of Earth mass around dim M‐dwarfs.

Gravitational Microlensing: Current Issues

2003
We briefly review four major issues currently being debated in observations of gravitational microlensing within the Local Group. Microlensing in the Galaxy has established that the baryonic denizens of the dark halo do not contribute significantly to its mass budget.
