TL;DR: The detection of a cool, sub-Neptune-mass planets may be more common than gas giant planets, as predicted by the core accretion theory, and is suggested to name OGLE-2005-BLG-390Lb, indicating a planetary mass companion to the lens star of the microlensing event.

TL;DR: The discovery of a population of unbound or distant Jupiter-mass objects is reported, which are almost twice as common as main-sequence stars, based on two years of gravitational microlensing survey observations towards the Galactic Bulge.

TL;DR: Two planets with masses that could not have been detected with other techniques are identified; their discovery from only six confirmed microlensing planet detections suggests that solar system analogs may be common.

TL;DR: The OGLE-2007-BLG-368Lb with a planet-star mass ratio of q = [9.5 ± 2.1] × 10^(-5] via gravitational microlensing was discovered in real-time thanks to the high cadence of the Microlensing Observations in Astrophysics survey and intensive followup observations.
