Great Data from GeMS!

Despite weather constrains and limitations in laser power, the Gemini Muti-Conjugate Adaptive Optics Systems (GeMS) recently completed a successful run, delivering lots of great data for users. According to Gemini astronomer Rodrigo Carrasco, the adaptive optics performance was good and uniform in the entire Gemini South Adaptive Optics Imager (GSAOI) field of view. The resolution varied between 65 milli-arcseconds and 85 milli-arcseconds.

During the run, the GeMS team completed a Large and Long Program lead by Principal Investigator and senior observer Dr. Tobias Fritz. Fritz is a postdoc at the University of Virginia.

Fritz leads an investigation aiming to constrain our galaxy’s shape and mass. His team is using GeMS/GSAOI to study the proper motions for a variety of stars in dwarf galaxies and globular clusters in the halo of the Milky Way.
