First Resolution of Microlensed Images of a Binary-lens Event

The Astrophysical Journal
We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI).

Single-epoch and Differential Astrometric Microlensing of Quasars

The Astrophysical Journal
We propose and discuss a new experimental approach to measure the centroid shift induced by gravitational microlensing in the images of lensed quasars (astrometric microlensing).

Simulations of Gravitational Microlensing

, 2011
Gravitational microlensing occurs when a massive lens (typically a star) deflects lightfrom a more distant source, creating two unresolvable images that are magnified. Theeffect is transient due to the motions of the lens and source, and the changing magnificationgives rise to a characteristic lightcurve.
