Dong, Subo, Bond, I. A., Gould, A., Kozlowski, Szymon, Miyake, N., Gaudi, B. S., ...
We report the detection of the cool, Jovian-mass planet MOA-2007-BLG-400Lb. The planet was detected in a high-magnification microlensing event (with peak magnification A_max = 628) in which the...
OGLE-2005-BLG-071Lb, the Most Massive M-Dwarf Planetary Companion? (2008)
Dong, Subo, Gould, Andrew, Udalski, Andrzej, Anderson, Jay, Christie, G. W., Gaudi, B. S., ...
We combine all available information to constrain the nature of OGLE-2005-BLG-071Lb, the second planet discovered by microlensing and the first in a high-magnification event. These include...
Discovery of a Very Bright, Nearby Gravitational Microlensing Event (2007)
Gaudi, B. Scott, Patterson, Joseph, Spiegel, David S., Krajci, Thomas, Koff, R., Pojmanski, G., ...
We report the serendipitous detection of a very bright, very nearby microlensing event. In late October 2006, an otherwise unremarkable A0 star at a distance ~1 kpc (GSC 3656-1328) brightened...
First Space-Based Microlens Parallax Measurement: Spitzer Observations of OGLE-2005-SMC-001 (2007)
Dong, Subo, Udalski, A., Gould, A., Reach, W. T., Christie, G. W., Boden, A. F., ...
We combine Spitzer and ground-based observations to measure the microlens parallax of OGLE-2005-SMC-001, the first such space-based determination since S. Refsdal proposed the idea in 1966. The...
Probing ~100 AU Intergalactic MgII Absorbing "Cloudlets" with Quasar Microlensing (2006)
Intergalactic MgII absorbers are known to have structures down to scales ~ 10^{2.5} pc, and there are now indications that they may be fragmented on scales
Planetary Detection Efficiency of the Magnification 3000 Microlensing Event OGLE-2004-BLG-343 (2005)
Dong, Subo, DePoy, D. L., Gaudi, B. S., Gould, A., Han, C., ...
OGLE-2004-BLG-343 was a microlensing event with peak magnification A_{max}=3000+/-1100, by far the highest-magnification event ever analyzed and hence potentially extremely sensitive to planets...
