Calibration of the MACHO Photometry Database
C. Alcock, R. A. Allsman, D. R. Alves +18
The MACHO Project is a microlensing survey that monitors the brightnesses of 60 million stars in the Large Magellanic Cloud (LMC), Small Magellanic Cloud, and Galactic bulge. Our d…
The DRIFT Project: Searching for WIMPS with a Directional Detector
M. J. Lehner, K. Griest, C. J. Martoff +4
A low pressure time projection chamber for the detection of WIMPs is discussed. Discrimination against Compton electron background in such a device should be very good, and directi…
Difference Image Analysis of Galactic Microlensing II. Microlensing Events
C. Alcock, R. A. Allsman, D. Alves +18
The MACHO collaboration has been carrying out Difference Image Analysis (DIA) since 1996 with the aim of increasing the sensitivity to the detection of gravitational microlensing.…
Difference Image Analysis of Galactic Microlensing I. Data Analysis
C. Alcock, R. A. Allsman, D. Alves +18
This is a preliminary report on the application of Difference Image Analysis (DIA) to galactic bulge images. The aim of this analysis is to increase the sensitivity to the detectio…
Cepheid Variables in the LMC and SMC
The MACHO Collaboration, D. L. Welch, C. Alcock +20
In this paper, we will review major new results regarding classical Cepheids, in the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC). Specifically, we discuss recent…
