Pushing the limits of near-infrared photometry with the Gemini Multi-Conjugate Adaptive Optics System: study of crowded fields in the globular cluster M5 [PDF]
Monthly notices of the Royal Astronomical SocietyWe present the deepest J – Ks near-infrared photometry of the globular cluster M5 (NGC 5904) from observations taken with the Gemini South Adaptive Optics Imager in tandem with the Gemini Multi-conjugate adaptive optics System (GeMS) on the 8.1m Gemini-

Accurate photometry with adaptive optics in the presence of anisoplanatic effects with a sparsely sampled PSF [PDF]
, 2009 Anisoplanatic effects can cause significant systematic photometric uncertainty in the analysis of dense stellar fields observed with adaptive optics. Program packages have been developed for a spatially variable PSF, but they require that a sufficient ...

Adaptive Optics Photometry and Astrometry of Binary Stars. II. A Multiplicity Survey of B Stars [PDF]
, 2007 We carried out a search for companions to B stars using the adaptive optics system of the Advanced Electro-Optical System 3.6 m telescope. We observed 70 B stars in the I band, finding 16 companions, 10 of which are newly discovered companions.
