We present an analysis of adaptive optics (AO) images from the Keck-I telescope of the microlensing event MOA-2011-BLG-262. The original discovery paper by Bennett et al. 2014 repo…
Microlensing brown-dwarf companions in binaries detected during the 2022 and 2023 seasons
Cheongho Han, Ian A. Bond, Andrzej Udalski +63
Building on previous works to construct a homogeneous sample of brown dwarfs in binary systems, we investigate microlensing events detected by the Korea Microlensing Telescope Netw…
Analysis of the full Spitzer microlensing sample I: Dark remnant candidates and Gaia predictions
Krzysztof A. Rybicki, Yossi Shvartzvald, Jennifer C. Yee +70
In the pursuit of understanding the population of stellar remnants within the Milky Way, we analyze the sample of microlensing events observed by the Spitzer Space Teles…
Four microlensing giant planets detected through signals produced by minor-image perturbations
Cheongho Han, Ian A. Bond, Chung-Uk Lee +63
We investigated the nature of the anomalies appearing in four microlensing events KMT-2020-BLG-0757, KMT-2022-BLG-0732, KMT-2022-BLG-1787, and KMT-2022-BLG-1852. The light curves o…
KMT-2023-BLG-1866Lb: Microlensing super-Earth around an M dwarf host
Cheongho Han, Ian A. Bond, Andrzej Udalski +64
We investigate the nature of the short-term anomaly that appears in the lensing light curve of KMT-2023-BLG-1866. The anomaly was only partly covered due to its short duration, les…
Influence of Black Hole Kick Velocity on Microlensing Distributions
Naoki Koshimoto, Norita Kawanaka, Daichi Tsuna
The natal kick velocity distribution for black holes (BHs) is unknown regardless of its importance for understanding the BH formation process. Gravitational microlensing is a uniqu…

Cheongho Han, Andrzej Udalski, Ian A. Bond +60
We undertake a project to reexamine microlensing data gathered from high-cadence surveys. The aim of the project is to reinvestigate lensing events with light curves exhibiting int…
Measurement of Dependence of Microlensing Planet Frequency on The Host Star Mass and Galactocentric Distance by using a Galactic Model
Kansuke Nunota, Naoki Koshimoto, Daisuke Suzuki +6
We measure the dependence of planet frequency on host star mass, , and distance from the Galactic center, , using a sample of planets discovered by gravitatio…
