OGLE-2018-BLG-0584 and KMT-2018-BLG-2119: two microlensing events with two lens masses and two source stars
Cheongho Han, Andrzej Udalski, Youn Kil Jung +34
We conduct a systematic investigation of the microlensing data collected during the previous observation seasons for the purpose of reanalyzing anomalous lensing events with no sug…
New Short-Period Delta Scuti Stars in OGLE-IV Fields toward the Galactic Bulge
P. Pietrukowicz, M. Ratajczak, I. Soszynski +12
We report the classification of 24 puzzling short-period variable stars located in OGLE-IV Galactic bulge fields. The stars are low-amplitude (<0.05 mag) multi-periodic objects wit…
Self-Supervised Clustering on Image-Subtracted Data with Deep-Embedded Self-Organizing Map
Y. -L. Mong, K. Ackley, T. L. Killestein +45
Developing an effective automatic classifier to separate genuine sources from artifacts is essential for transient follow-ups in wide-field optical surveys. The identification of t…
Brown-dwarf companions in microlensing binaries detected during the 2016--2018 seasons
Cheongho Han, Yoon-Hyun Ryu, In-Gu Shin +60
With the aim of finding microlensing binaries containing brown-dwarf (BD) companions, we investigate the microlensing survey data collected during the 2016--2018 seasons. For this…
The Gravitational-wave Optical Transient Observer (GOTO)
Martin J. Dyer, Kendall Ackley, Joe Lyman +12
The Gravitational-wave Optical Transient Observer (GOTO) is a wide-field telescope project focused on detecting optical counterparts to gravitational-wave sources. Each GOTO roboti…
OGLE-2019-BLG-0362Lb: A super-Jovian-mass planet around a low-mass star
Sun-Ju Chung, Jennifer C. Yee, Andrej Udalski +28
We present the analysis of a planetary microlensing event OGLE-2019-BLG-0362 with a short-duration anomaly near the peak of the light curve, which is caused…
