Using Orbital Effects to Break the Close/wide Degeneracy in Binary-lens Microlensing Events
I. -G. Shin, T. Sumi, A. Udalski +37
Microlensing can provide an important tool to study binaries, especially those composed of faint or dark objects. However, accurate analysis of binary-lens light curves is often ha…
Microlensig Binaries with Candidate Brown Dwarf Companions
I. -G. Shin, C. Han, A. Gould +152
Brown dwarfs are important objects because they may provide a missing link between stars and planets, two populations that have dramatically different formation history. In this pa…
Measurement of zero degree inclusive photon energy spectra for 900 GeV proton-proton collisions at LHC

The inclusive photon energy spectra measured by the Large Hadron Collider forward (LHCf) experiment in the very forward region of LHC proton-proton collisions at 900 Ge…
A possible binary system of a stellar remnant in the high magnification gravitational microlensing event OGLE-2007-BLG-514
N. Miyake, A. Udalski, T. Sumi +78
We report the extremely high magnification (A > 1000) binary microlensing event OGLE-2007-BLG-514. We obtained good coverage around the double peak structure in the light curve via…
