First Space-Based Microlens Parallax Measurement: Spitzer Observations of OGLE-2005-SMC-001
Subo Dong, A. Udalski, A. Gould +20
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…
Removing the Microlensing Blending-Parallax Degeneracy Using Source Variability
R. J. Assef, A. Gould, the EROS-2 +2
Microlensing event MACHO 97-SMC-1 is one of the rare microlensing events for which the source is a variable star, simply because most variable stars are systematically eliminated f…
Fitting Photometry of Blended Microlensing Events
Christian L. Thomas, Kim Griest
We reexamine the usefulness of fitting blended lightcurve models to microlensing photometric data. We find agreement with previous workers (e.g. Wozniak & Paczynski) that this is a…
Contamination in the MACHO dataset and the puzzle of LMC Microlensing
Kim Griest, Christian L. Thomas
In a recent series of three papers, Belokurov, Evans, and Le Du, and Evans and Belokurov, reanalysed the MACHO collaboration data and gave alternative sets of microlensing events a…
Galactic Bulge Microlensing Events from the MACHO Collaboration
C. L. Thomas, K. Griest, P. Popowski +21
We present a catalog of 450 high signal-to-noise microlensing events observed by the MACHO collaboration between 1993 and 1999. The events are distributed throughout our fields and…
Microlensing Optical Depth towards the Galactic Bulge Using Clump Giants from the MACHO Survey
P. Popowski, K. Griest, C. L. Thomas +20
Using 7 years of MACHO survey data, we present a new determination of the optical depth to microlensing towards the Galactic bulge. We select the sample of 62 microlensing events (…
