The MACHO Project: 45 Candidate Microlensing Events from the First Year Galactic Bulge Data
C. Alcock, R. A. Allsman, T. S. Axelrod +15
We report the detection of 45 candidate microlensing events in fields toward the Galactic bulge. These come from the analysis of 24 fields containing 12.6 million stars observed fo…
First Observation of Parallax in a Gravitational Microlensing Event
C. Alcock, R. A. Allsman, D. Alves +14
We present the first detection of parallax effects in a gravitational microlensing event. Parallax in a gravitational microlensing event observed only from the Earth appears as a d…
The MACHO Project First Year LMC Results: The Microlensing Rate and the Nature of the Galactic Dark Halo
C. Alcock, R. A. Allsman, T. S. Axelrod +15
The MACHO collaboration reports on the analysis of our first year LMC data, 9.5 million light curves with an average of 235 observations each. Automated selection procedures give 3…
