TL;DR: In this paper, the OGLE-2016-BLG-1227 microlensing event appears to be a single-lens event affected by severe finite-source effects, and the residuals are explained by the existence of an additional widely separated heavier lens component, indicating that the lens is a wide-separation planetary system rather than a free-floating planet.

TL;DR: In this paper, the authors show that the perturbation at the peak of the light curve of microlensing event KMT-2019-BLG-0371 is explained by a model with a mass ratio between the host star and planet of 0.08.

TL;DR: In this paper, the authors presented the most comprehensive picture of the central parts of the Milky Way probed with RR Lyrae variable stars, which consists of 38257 RR Lyr stars detected over 182 square degrees by the Optical Gravitational Lensing Experiment (OGLE) in the most central regions of the Galactic bulge.

TL;DR: In this paper, the authors search for microlensing planets with signals exhibiting no caustic-crossing features, considering the possibility that such signals may be missed due to their weak and featureless nature.
