Long Period Variables in the LMC: Results from MACHO and 2MASS
Oliver J. Fraser, Suzanne L. Hawley, Kem H. Cook +1
We use the eight year light-curve database from the MACHO (MAssive Compact Halo Objects) project together with infrared colors and magnitudes from 2MASS (the Two Micron All Sky Sur…
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 (…
The SuperMACHO Microlensing Survey
A. C. Becker, A. Rest, C. Stubbs +18
We present the first results from our next-generation microlensing survey, the SuperMACHO project. We are using the CTIO 4m Blanco telescope and the MOSAIC imager to carry out a se…
Resolving the Nature of the LMC Microlensing Event LMC-5
A. J. Drake, K. H. Cook, S. C. Keller
We present the results from an analysis of Hubble Space Telescope High Resolution Camera data for the Large Magellanic Cloud microlensing event MACHO-LMC-5. By determining the para…
