Progress with Adaptive Optics Testbeds at the UCO/Lick Observatory Laboratory for Adaptive Optics
We report on experimental results with adaptive optics testbeds at the UCO/Lick Observatory. One testbed is dedicated to high contrast AO imaging and is a prototype for a ground-based extrasolar planet imager for the Gemini telescope. The second testbed is dedicated to developing concepts and architectures for multilaser guidestar tomography in wide-field AO applications. Such systems are now u...
متن کاملArnica: the Arcetri Observatory Nicmos 3 Imaging Camera
ARNICA (ARcetri Near Infrared CAmera) is the imaging camera for the near infrared bands between 1.0 and 2.5 m that Arcetri Observatory has designed and built as a general facility for the TIRGO telescope (1.5 m diameter, f/20) located at Gornergrat (Switzerland). The scale is 100 per pixel, with sky coverage of more than 40 40 on the NICMOS 3 (256 256 pixels, 40 m side) detector array. The opti...
متن کاملTwo components of responding in Pavlovian lick suppression.
The present research examined the temporal distribution of responding in a lick suppression paradigm. In Experiment 1, rats were trained with either a 30- or a 120-s conditioned stimulus (CS), which was followed either by a footshock (unconditioned stimulus [US]) or nothing. Licking during the CS was suppressed only in the former condition. Suppression was more pronounced early in the CS. In Ex...
متن کاملThe Two Micron All-Sky Survey: Removing the Infrared Foreground
We introduce the properties of the Two Micron All-Sky Survey (2MASS) survey for IAU Symposium 204. 2MASS is a near-infrared survey of the entire sky characterized by high reliability and completeness. Catalogs and images for 47% of the sky are now available online. This data release has been used by Wright (2000) and Cambrésy et al. (2000) to subtract the stellar foreground at 1.25 and 2.2 micr...
متن کاملTwo Exoplanets Discovered at Keck Observatory
We present two exoplanets detected at Keck Observatory. HD 179079 is a G5 subgiant that hosts a hot Neptune planet with M sin i = 27.5 M⊕ in a 14.48 d, low-eccentricity orbit. The stellar reflex velocity induced by this planet has a semiamplitude of K = 6.6 m s. HD 73534 is a G5 subgiant with a Jupiter-like planet of M sin i = 1.1 MJup and K = 16 m s −1 in a nearly circular 4.85 yr orbit. Both ...
