A new component of the Galaxy as the origin of the LMC microlensing events
Evalyn Gates, Geza Gyuk
We suggest a new component of the Milky Way that can account for both the optical depth and event durations implied by microlensing searches targeting the Large Magellanic Cloud. T…
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…
LMC Microlensing and Very Thick Disks
Geza Gyuk, Evalyn Gates
We investigate the implications of a very thick (scale height 1.5 - 3.0 kpc) disk population of MACHOs. Such a population represents a reasonable alternative to standard halo confi…
Microlensing and the Composition of the Galactic Halo
Evalyn Gates, Geza Gyuk, Michael S. Turner
By means of extensive galactic modeling we study the implications of the more than 100 microlensing events that have now been observed for the composition of the dark halo of the G…
MACHOs: The Plot Thickens
Michael S. Turner, Evalyn I. Gates, Geza Gyuk
We discuss the implications of the recent upward revision of the LMC microlensing rate by the MACHO Collaboration. We conclude: (i) A good case for the existence of baryonic dark m…
