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…

OGLE-2018-BLG-0971, MOA-2023-BLG-065, and OGLE-2023-BLG-0136: Microlensing events with prominent orbital effects

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…

Precise mass measurement of OGLE-2013-BLG-0132/MOA-2013-BLG-148: a Saturn mass planet orbiting an M-dwarf

Natalia E. Rektsini, Virginie Batista, Clement Ranc +10

We revisit the planetary microlensing event OGLE-2013-BLG-0132/MOA-2013-BLG-148 using Keck adaptive optics imaging in 2013 with NIRC2 and in 2020, 7.4 years after the event, with O…

MOA-2022-BLG-563Lb, KMT-2023-BLG-0469Lb, and KMT-2023-BLG-0735Lb: Three sub-Jovian-mass microlensing planets

Cheongho Han, Youn Kil Jung, Ian A. Bond +45

We analyze the anomalies appearing in the light curves of the three microlensing events MOA-2022-BLG-563, KMT-2023-BLG-0469, and KMT-2023-BLG-0735. The anomalies exhibit common sho…
