Final review of adaptive optics results from the pre-conversion MMT (2007)
M. Lloyd-hart, M. Lloyd-hart, R. Angel, R. Angel, T. Groesbeck, ...
The FASTTRAC II adaptive optics instrument has been used at the Multiple Mirror Telescope (MMT) for the past 2 years to provide improved image resolution in the near infrared. Results have been...
Diffraction-limited K-band imaging at the Multiple Mirror Telescope with adaptive optics (2007)
M. Lloyd-hart, D. Colucci, D. Wittman, B. Mcleod, A. Ghez, ...
Low spatial frequencies of atmospheric turbulence are specially troublesome to astronomers because the phase distortions they cause have large amplitude. We have begun experiments at the Multiple...

Progress in Diffraction-Limited Imaging at the Multiple Mirror Telescope with Adaptive Optics (2007)
M. Lloyd-hart, R. Dekany, D. Sandler, D. Wittman, R. Angel, D. Mccarthy
this paper were obtained using only the five mirrors highlighted in Fig. 1. With no aberration, the point spread function of this array appears as shown in Fig. 2, with a bright central peak...
Infrared adaptive optics system for the 6.5 m MMT: system status and prototype results (2007)
Lloyd-Hart Angel, R. Angel, D. Sandler, T. Barrett, P. Mcguire, T Rhoadarmer, ...
The Multiple Mirror Telescope (MMT) is now being replaced by a single 6.5 m telescope 1 which will have an integral adaptive optics system optimized for near infrared operation. We illustrate key...
The “Meaning ” System on the English Allwords Task (2007)
L. Villarejoý, L. Màrquezý, E. Agirreþ, D. Martínezþ, B. Magnini, D. Mccarthy, ...
The “Meaning ” system has been developed within the framework of the Meaning European research project 1. It is a combined system, which integrates several supervised machine learning word sense
A Re-evaluation of the Eastern and Western Records of the Supernova of 1054 (2007)
The Chinese and Japanese records are our primary evidence of the supernova of 1054. But their evidence is not entirely consistent, and recent scholarly discussion of them has not yielded clear-cut...
Nicmos/hst Post-Perihelion Images Of Comet Hale--Bopp (2007)
In Outburst Mccarthy, D. Mccarthy, S. Stolovy, S. Kern, G. Schneider, A. Ferro, ...
Near-infrared images of comet Hale--Bopp (C/1995 O1) were obtained from NICMOS /HST on UT August 27--28, 1997, when the comet emerged from the 50 degree solar elongation limit at 2.99 AU from Earth....
