A New (Old) Component of the Galaxy as the Origin of the Observed LMC Microlensing Events
Evalyn I. Gates, Geza Gyuk
We suggest a new component of the Milky Way galaxy that can account for both the optical depth and the event durations obtained by the MACHO microlensing survey toward the Large Ma…
MEGA, a Wide-Field Survey of Microlensing in M31
A. P. S. Crotts, R. Uglesich, G. Gyuk
We detail how microlensing internal to M31 could be used to test whether a large fraction of the matter in spiral galaxy haloes is composed of dark objects with masses comparable t…
Expectations from Realistic Microlensing Models of M31. I: Optical Depth
Geza Gyuk, Arlin Crotts
We provide a set of microlensing optical depth maps for M31. Optical depths towards Andromeda were calculated on the basis of a four component model of the lens and source populati…
A Possible Explanation for the Radio ``Flare'' in the Early Afterglow of GRB990123
Xiangdong Shi, Geza Gyuk
We suggest that the deceleration of the relativistic shock by a denser part of the interstellar medium off line-of-sight produced the observed radio ``flare'' in the early afterglo…
