The Effective Cross-sections of a Lensing-galaxy: Singular Isothermal Sphere with External Shear
Dong-Wook Lee, Sang-Joon Kim
Numerical studies on the imaging and caustic properties of the singular isothermal sphere (SIS) under a wide range of external shear (from 0.0 to 2.0) are presented. Using a direct…
Microlensing Detections of Planets in Binary Stellar Systems
Dong-Wook Lee, Chung-Uk Lee, Byeong-Gon Park +4
We demonstrate that microlensing can be used for detecting planets in binary stellar systems. This is possible because in the geometry of planetary binary systems where the planet…
Properties of Central Caustics in Planetary Microlensing
Sun-Ju Chung, Cheongho Han, Byeong-Gon Park +9
To maximize the number of planet detections, current microlensing follow-up observations are focusing on high-magnification events which have a higher chance of being perturbed by…
Reconstruction of the microlensing light curves of the Einstein Cross, QSO2237+0305: possible evidence of an accretion disk with a central hole
Dong-Wook Lee, J. Surdej, O. Moreau +2
Recent OGLE (Optical Gravitational Lensing Experiment) and GLITP (Gravitational Lens International Time Project) monitoring data for QSO 2237+0305 (Huchra et al.) have been analyze…
Constraints on Scalar-Field Dark Energy from the Cosmic Lens All-Sky Survey Gravitational Lens Statistics
Kyu-Hyun Chae, Gang Chen, Bharat Ratra +1
We use the statistics of strong gravitational lensing based on the Cosmic Lens All-Sky Survey (CLASS) data to constrain cosmological parameters in a spatially-flat, inverse power-l…
