New Constraints on Quasar Broad Absorption and Emission Line Regions from Gravitational Microlensing [PDF]
Frontiers in Astronomy and Space Sciences, 2017 Gravitational microlensing is a powerful tool allowing one to probe the structure of quasars on sub-parsec scale. We report recent results, focusing on the broad absorption and emission line regions.

Effect of Deviations from General Relativity on Searches for Gravitational-wave Microlensing and Type II Strong Lensing [PDF]
The Astrophysical JournalAs the gravitational-wave (GW) detector network is upgraded and the sensitivity of the detectors improves, novel scientific avenues open for exploration. For example, tests of general relativity (GR) will become more accurate as smaller deviations can be

GRAVITATIONAL MICROLENSING AND EXTENDED SOURCE MODELS
Odessa Astronomical Publications, 2014 We perform statistical simulations of light curves of extended microlensed sources having different brightness distribution in the source plane. We generated a set of realizations of lensing point mass system that takes into account an external shear ...

Mass Production of 2021 KMTNet Microlensing Planets II
The Astronomical Journal, 2023 We continue our program of publishing all planets (and possible planets) found by eye in 2021 Korea Microlensing Telescope Network (KMTNet) online data. We present four planets (KMT-2021-BLG-0712Lb, KMT-2021-BLG-0909Lb, KMT-2021-BLG-2478Lb, and KMT-2021 ...

Systematic KMTNet Planetary Anomaly Search. VIII. Complete Sample of 2019 Subprime Field Planets
The Astronomical Journal, 2023 We complete the publication of all microlensing planets (and “possible planets”) identified by the uniform approach of the KMT AnomalyFinder system in the 21 KMT subprime fields during the 2019 observing season, namely, KMT-2019-BLG-0298, KMT-2019-BLG ...

Microlensing Searches for Exoplanets
Geosciences, 2018 Gravitational microlensing finds planets through their gravitational influence on the light coming from a more distant background star. The presence of the planet is then inferred from the tell-tale brightness variations of the background star during the
