Mapping the Galactic Halo III. Simulated Observations of Tidal Streams
Paul Harding, Heather L. Morrison, Edward W. Olszewski +5
We have simulated the evolution of tidal debris in the Galactic halo in order to guide our ongoing survey to determine the fraction of halo mass accreted via satellite infall. Cont…
Mapping the Galactic Halo IV. Finding Distant Giants Reliably with the Washington System
H. L. Morrison, E. W. Olszewski, M. Mateo +4
We critically examine the use of the Washington photometric system (with the 51 filter) for identifying distant halo giants. While this is the most powerful photometric technique f…
A 421 d Activity Cycle in the BeX Recurrent Transient A0538-66 from MACHO monitoring
C. Alcock, R. A. Allsman, D. R. Alves +23
We present a ~ 5-yr optical light curve of the recurrent Be/X-ray transient A0538-66 obtained as a by-product of the MACHO Project. These data reveal both a long-term modulation at…
The MACHO Project Hubble Space Telescope Follow-Up: Preliminary Results on the Location of the Large Magellanic Cloud Microlensing Source Stars
C. Alcock, R. A. Allsman, D. R. Alves +21
We attempt to determine whether the MACHO microlensing source stars are drawn from the average population of the LMC or from a population behind the LMC by examining the HST color-…
Mapping the Galactic Halo II: Photometric Survey
R. C. Dohm-Palmer, Mario Mateo, E. Olszewski +4
We present imaging results from a high Galactic latitude survey designed to examine the structure of the Galactic halo. The objective of the survey is to identify candidate halo st…
Galactic Bulge Microlensing Events with Clump Giants as Sources
P. Popowski, C. Alcock, R. A. Allsman +21
We present preliminary results of the analysis of 5 years of MACHO data on the Galactic bulge microlensing events with clump giants as sources. In particular, we discuss: 1) the se…
