OGLE-2019-BLG-0468Lb,c: two microlensing giant planets around a G-type star
Cheongho Han, Andrzej Udalski, Chung-Uk Lee +37
With the aim of interpreting anomalous lensing events with no suggested models, we conducted a project of reinvestigating microlensing data in and before the 2019 season. In this w…
The Unanticipated Phenomenology of the Blazar PKS~2131021: A Unique Super-Massive Black Hole Binary Candidate
S. O'Neill, S. Kiehlmann, A. C. S. Readhead +24
Most large galaxies host supermassive black holes in their nuclei and are subject to mergers, which can produce a supermassive black hole binary (SMBHB), and hence periodic signatu…
Three faint-source microlensing planets detected via resonant-caustic channel
Cheongho Han, Andrzej Udalski, Doeon Kim +32
We conducted a project of reinvestigating the 2017--2019 microlensing data collected by the high-cadence surveys with the aim of finding planets that were missed due to the deviati…
Using Source Proper Motion to Validate Terrestrial Parallax: OGLE-2019-BLG-1058
In-Gu Shin, Jennifer C. Yee, Kyu-Ha Hwang +30
We show that because the conditions for producing terrestrial microlens parallax (TPRX; i.e., a nearby disk lens) will also tend to produce a large lens-source relative proper moti…
Systematic KMTNet Planetary Anomaly Search, Paper II: Six New Mass-ratio Planets
Kyu-Ha Hwang, Weicheng Zang, Andrew Gould +62
We apply the automated AnomalyFinder algorithm of Paper I (Zang et al. 2021b) to 2018-2019 light curves from the covered by the six KMTNet prime fields, wi…
Three microlensing planets with no caustic-crossing features
Cheongho Han, Andrzej Udalski, Doeon Kim +31
We search for microlensing planets with signals exhibiting no caustic-crossing features, considering the possibility that such signals may be missed due to their weak and featurele…
