The Angstrom Project Alert System: real-time detection of extragalactic microlensing
M. J. Darnley, E. Kerins, A. Newsam +9
The Angstrom Project is undertaking an optical survey of stellar microlensing events across the bulge region of the Andromeda Galaxy (M31) using a distributed network of two-meter…
Emergence of Chaotic Itinerancy in Simple Ecological Systems
Pan-Jun Kim, Tae-Wook Ko, Hawoong Jeong +2
Chaotic itinerancy is a universal dynamical concept that describes itinerant motion among many different ordered states through chaotic transition in dynamical systems. Unlike the…
Blending in Future Space-based Microlensing Surveys
Cheongho Han, Byeong-Gon Park, Ho-Il Kim +1
We investigate the effect of blending in future gravitational microlensing surveys by carrying out simulation of Galactic bulge microlensing events to be detected from a proposed s…
Instanton interpolating current for --tetraquark
Hee-Jung Lee, N. I. Kochelev
We perform a QCD sum rule analysis for the light scalar meson () with a tetraquark current related to the instanton picture for QCD vacuum. We demonstrate that instan…
The secondary star and distance of the polar V1309 Ori
K. Reinsch, Y. Kim, K. Beuermann
The first phase-resolved JHK light curves of the eclipsing polar (AM Herculis binary) V1309 Ori are presented and interpreted. We separate the contributions from the secondary star…
Microlens OGLE-2005-BLG-169 Implies Cool Neptune-Like Planets are Common
A. Gould, A. Udalski, D. An +33
We detect a Neptune mass-ratio (q~8e-5) planetary companion to the lens star in the extremely high-magnification (A~800) microlensing event OGLE-2005-BLG-169. If the parent is a ma…
