The population of dark and isolated compact objects in the Galaxy contains critical information related to many of these topics, but is only practically accessible via gravitational microlensing.

We report the discovery of the first candidate microlensing event to be discovered in the direction of the Galactic Bulge. The peak brightness of the candidate event occurred on June 15, 1993. The ...

Utilizing realistic models for both the BAL region and the action of an ensemble of microlensing masses, we demonstrate that stars at cosmological distances can provide an important probe of the ...

Earth-like exoplanets might be more common throughout the Milky Way than previously believed, astronomers report in a new study.

Over the past decade or so, astronomers have speculated about the characteristics of rogue planets in the Milky Way galaxy. These "free-floating" worlds don't orbit stars, but instead roam the ...

The nature and the location of the lenses discovered in the microlensing surveys done so far towards the LMC remain unclear. Motivated by these questions we ... literature Help Submit Login Literature ...

A star racing at high speed through our galaxy is dragging along a massive planet. This discovery surprises scientists, who expected the planet to be ejected during such a cosmic journey.
