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…
A Lens Finder Map to check claimed High-z Galaxies behind SMACS J0723.3-7327
Alex Chow, Sung Kei Li, Tom Broadhurst +5
The first science image released by the JWST reveals numerous galaxies in the distant background of the galaxy cluster SMACS J0723.3-7327. Some have claimed redshifts of up to $z \…
KMT-2021-BLG-0171Lb and KMT-2021-BLG-1689Lb: Two Microlensing Planets in the KMTNet High-cadence Fields with Followup Observations
Hongjing Yang, Weicheng Zang, Andrew Gould +56
Follow-up observations of high-magnification gravitational microlensing events can fully exploit their intrinsic sensitivity to detect extrasolar planets, especially those with sma…
KMT-2021-BLG-0322: Severe degeneracy between triple-lens and higher-order binary-lens interpretations
Cheongho Han, Andrew Gould, Yuki Hirao +46
We investigate the microlensing event KMT-2021-BLG-0322, for which the light curve exhibits three distinctive sets of caustic-crossing features. It is found that the overall featur…
Systematic KMTNet Planetary Anomaly Search, Paper I: OGLE-2019-BLG-1053Lb, A Buried Terrestrial Planet
Weicheng Zang, Kyu-Ha Hwang, Andrzej Udalski +69
In order to exhume the buried signatures of "missing planetary caustics" in the KMTNet data, we conducted a systematic anomaly search to the residuals from point-source point-lens…
OGLE-2018-BLG-0799Lb: a Planet with Spitzer Parallax
Weicheng Zang, Yossi Shvartzvald, Andrzej Udalski +73
We report the discovery and analysis of a planet in the microlensing event OGLE-2018-BLG-0799. The planetary signal was observed by several ground-based telescopes, and the planet-…
