The Proper Motion of Pyxis: The First Use of Adaptive Optics in Tandem with HST on a Faint Halo Object
Tobias K. Fritz,Sean T. Linden,Paul Zivick,Nitya Kallivayalil,Rachael L. Beaton,Jo Bovy,Laura V. Sales,T. Sohn,Dylan Angell,Michael Boylan-Kolchin,Eleazar R. Carrasco,Guillermo Damke,Ric Davies,S. R. Majewski,Benoit Neichel,R. P. van der Marel +15 more
TL;DR: In this paper, a proper motion measurement for the halo globular cluster Pyxis is presented, using HST/ACS data as the first epoch, and GeMS/GSAOI Adaptive Optics data for the second epoch, separated by a baseline of about 5 years.

Tobias K. Fritz,Nitya Kallivayalil,Eleazar R. Carrasco,Benoit Neichel,Richard Davies,Rachael L. Beaton,Dylan Angell,Sean T. Linden,Paul Zivick,Steve Majewski,Guillermo Damke,M. Boylan-Kolchin,Roeland P. van der Marel,T. Sohn +13 more
TL;DR: In this paper, the authors present a first analysis of the astrometric error budget of absolute astrometry relative to background galaxies using adaptive optics, using multi-conjugated adaptive optics (MCAO) images obtained with GeMS/GSAOI at Gemini South.
