OGLE-2017-BLG-0448Lb: A Low Mass-Ratio Wide-Orbit Microlensing Planet?

Ruocheng Zhai, Radosław Poleski, Weicheng Zang +38

The gravitational microlensing technique is most sensitive to planets in a Jupiter-like orbit and has detected more than 200 planets. However, only a few wide-orbit () micro…

OGLE-2019-BLG-1180Lb: Discovery of a Wide-orbit Jupiter-mass Planet around a Late-type Star

Sun-Ju Chung, Andrzej Udalski, Jennifer C. Yee +30

We report on the discovery and analysis of the planetary microlensing event OGLE-2019-BLG-1180 with a planet-to-star mass ratio . The event OGLE-2019-BLG-1180 has una…

KMT-2023-BLG-1431Lb: A New Microlensing Planet from a Subtle Signature

Aislyn Bell, Jiyuan Zhang, Youn Kil Jung +70

The current studies of microlensing planets are limited by small number statistics. Follow-up observations of high-magnification microlensing events can efficiently form a statisti…

Systematic Reanalysis of KMTNet microlensing events, Paper I: Updates of the Photometry Pipeline and a New Planet Candidate

Hongjing Yang, Jennifer C. Yee, Kyu-Ha Hwang +52

In this work, we update and develop algorithms for KMTNet tender-love care (TLC) photometry in order to create an new, mostly automated, TLC pipeline. We then start a project to sy…

Gravitational-wave Electromagnetic Counterpart Korean Observatory (GECKO): GECKO Follow-up Observation of GW190425

Gregory S. H. Paek, Myungshin Im, Joonho Kim +13

One of the keys to the success of multimessenger astronomy is the rapid identification of the electromagnetic wave counterpart, kilonova (KN), of the gravitational-wave (GW) event.…

KMT-2021-BLG-1547Lb: Giant microlensing planet detected through a signal deformed by source binarity

Cheongho Han, Weicheng Zang, Youn Kil Jung +52

We investigate the previous microlensing data collected by the KMTNet survey in search of anomalous events for which no precise interpretations of the anomalies have been suggested…
