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…
OGLE-2019-BLG-0825: Constraints on the Source System and Effect on Binary-lens Parameters arising from a Five Day Xallarap Effect in a Candidate Planetary Microlensing Event
Yuki K. Satoh, Naoki Koshimoto, David P. Bennett +86
We present an analysis of microlensing event OGLE-2019-BLG-0825. This event was identified as a planetary candidate by preliminary modeling. We find that significant residuals from…
Brown dwarf companions in binaries detected from the 2021 season high-cadence microlensing surveys
Cheongho Han, Youn Kil Jung, Ian A. Bond +45
As a part of the project aiming to build a homogeneous sample of binary-lens (2L1S) events containing brown-dwarf (BD) companions, we investigate the 2021 season microlensing data…
KMT-2022-BLG-0475Lb and KMT-2022-BLG-1480Lb: Microlensing ice giants detected via non-caustic-crossing channel
Cheongho Han, Chung-Uk Lee, Ian A. Bond +49
We investigate the microlensing data collected in the 2022 season from the high-cadence microlensing surveys in order to find weak signals produced by planetary companions to lense…
Roman CCS White Paper: Characterizing the Galactic population of isolated black holes
Casey Y. Lam, Natasha Abrams, Jeff Andrews +34
Although there are estimated to be 100 million isolated black holes (BHs) in the Milky Way, only one has been found so far, resulting in significant uncertainty about their propert…
KMT-2021-BLG-1150Lb: Microlensing planet detected through a densely covered planetary-caustic signal
Cheongho Han, Youn Kil Jung, Ian A. Bond +49
Recently, there have been reports of various types of degeneracies in the interpretation of planetary signals induced by planetary caustics. In this work, we check whether such deg…
