We will present a system to perform closed-loop optical tests of the 64 cm diameter, 336 actuator adaptive secondary made at the Steward Observatory Mirror Laboratory. T esting will include Shack-Hartmann wavefront sensing and modal correction of static and dynamic aberrated wavefronts. The test optical system called thèShimmulator' is designed so that(More)
We present the first scientific images obtained with a deformable secondary mirror adaptive optics system. We utilized the 6.5m MMT AO system to produce high-resolution (FWHM=0.07 ′′) near infrared (1.6µm) images of the young (∼ 1 Myr) Orion Trapezium θ 1 Ori cluster members. A combination of high spatial resolution and high signal to noise allowed the(More)
INTRODUCTION Isolated cases of epicarditis are rare. Thus far, all have occurred with constrictive physiology as most cases involve both parietal and visceral pericardium. We report the first case of asymptomatic epicarditis that involved only the visceral pericardium presenting without constrictive physiology. CASE PRESENTATION A 71-year-old male with a(More)
