VATT/Columbia Microlensing Survey of M31 and the Galaxy
Arlin P. S. Crotts
We describe the results and outline the methods used in a search for microlensing events affecting stars in the outer bulge and inner disk of M31, due both to masses in M31 and the…
Expanding the Realm of Microlensing Surveys with Difference Image Photometry
Austin B. Tomaney, Arlin P. S. Crotts
We present a new technique for monitoring microlensing activity even in highly crowded fields, and use this technique to place limits on low-mass MACHOs in the haloes of M31 and th…
Results from a Survey of Gravitational Microlensing towards M31
Arlin P. S. Crotts, Austin B. Tomaney
We describe the results of a search for microlensing events affecting stars in the outer bulge and inner disk of M31, due both to masses in M31 and the Galaxy. These observations,…
Physical Conditions in Low Ionization Regions of the Orion Nebula
J. A. Baldwin, A. Crotts, R. J. Dufour +12
We reexamine the spectroscopic underpinnings of recent suggestions that [O I] and [Fe II] lines from the Orion H II region are produced in gas where the iron-carrying grains have b…
