Recent Developments in Gravitational Microlensing and the Latest MACHO Results: Microlensing Towards the Galactic Bulge
D. P. Bennett, C. Alcock, R. A. Allsman +12
We review recent gravitational microlensing results from the EROS, MACHO, and OGLE collaborations, and present some details of the very latest MACHO results toward the Galactic Bul…
The MACHO Project LMC Variable Star Inventory: I. Beat Cepheids - Conclusive Evidence for the Excitation of the Second Overtone in Classical Cepheids
C. Alcock, R. A. Allsman, T. S. Axelrod +13
We report the discovery of 45 beat Cepheids in the Large Magellanic Cloud (LMC) using the MACHO Project photometry database. The variables which are pulsating simultaneously in two…
Theory of Exploring the Dark Halo with Microlensing 1: Power--Law Models
C. Alcock, R. A. Allsman, T. S. Axelrod +15
The detection of microlensing has opened the way for the development of new methods in galactic astronomy. This series of papers investigates what microlensing can teach us about t…
Gravitational Microlensing Results from Macho
W. Sutherland, C. Alcock, R. Allsman +13
We provide a status report on our search for dark matter in our Galaxy in the form of massive compact halo objects (MACHOs), using gravitational microlensing of background stars. T…
Probable Gravitational Microlensing towards the Galatic Bulge
C. Alcock, R. Allsman, T. Axelrod +13
The MACHO project carries out regular photometric monitoring of millions of stars in the Magellanic Clouds and Galactic Bulge, to search for very rare gravitational microlensing ev…
