TL;DR: In this paper, the authors presented the analysis of OGLE-2018-BLG-0022 that is detected toward the Galactic bulge field and demonstrated that the dense and continuous coverage with the high-quality photometry data from ground-based observations combined with the space-based Spitzer observations of this long timescale event enables them to uniquely determine the masses M1 = 0.40 ± 0.05Me and M2=0.13 − 0.01Me of the individual lens components.

TL;DR: In this article, the authors reported the discovery of a cold planet with a very low planet/host mass ratio of $q=(4.09\pm0.27) \times 10^{-5}$, which is similar to the ratio of Uranus/Sun in the Solar system.

TL;DR: WFIRST is NASA's first flagship mission with pre-defined core science programs to study dark energy and perform a statistical census of wide orbit exoplanets with a gravitational microlensing survey as discussed by the authors.

TL;DR: A set of high level data products are proposed that will enable astronomers without detailed microlensing expertise access to the statistical implications of the WFIRST exoplanetmicrolensing survey data and the formation of a WFIRst Exoplanet Microlensing Community Science Team is proposed.

TL;DR: In this article, the authors summarize current and planned exoplanet detection programs using a variety of methods: microlensing (including WFIRST), radial velocities, Gaia astrometry, and direct imaging.
