Abstract The Wide Field InfraRed Survey Telescope (WFIRST) is the next NASA
astrophysics flagship mission, to follow the James Webb Space Telescope. The WFIRST …

We report the results of the statistical analysis of planetary signals discovered in MOA-II
microlensing survey alert system events from 2007 to 2012. We determine the survey …

We report the analysis of OGLE-2019-BLG-0960, which contains the smallest mass-ratio
microlensing planet found to date (q= 1.2–1.6× 10− 5 at 1σ). Although there is substantial …

We report the complete statistical planetary sample from the prime fields (Γ≥ 2 h− 1) of the
2019 Korea Microlensing Telescope Network (KMTNet) microlensing survey. We develop …

In order to exhume the buried signatures of" missing planetary caustics" in Korea
Microlensing Telescope Network (KMTNet) data, we conducted a systematic anomaly …

We combine Spitzer and ground-based observations to measure the microlens parallax
vector ${\boldsymbol {\pi}} _ {\rm E} $, and thus the mass and distance of OGLE-2014-BLG …

We present a statistical analysis of the first four seasons from a 'second-generation'
microlensing survey for extrasolar planets, consisting of near-continuous time coverage of 8 …

We present the analyses of two microlensing events, OGLE-2018-BLG-0567 and OGLE-
2018-BLG-0962. In both events, the short-lasting anomalies were densely and continuously …

We report the discovery of KMT-2020-BLG-0414Lb, with a planet-to-host mass ratio q 2= 0.9–
1.2× 10− 5= 3–4⊕ at 1σ, which is the lowest mass-ratio microlensing planet to date …

Space-based microlens parallax measurements are a powerful tool for understanding planet
populations, especially their distribution throughout the Galaxy. However, if space-based …
