Getting Lucky with Adaptive Optics: Fast AO Image Selection in the Visible with a Large Telescope
N. M. Law, C. D. Mackay, R. G. Dekany +6
We describe the results from a new instrument which combines Lucky Imaging and Adaptive Optics to give the first routine direct diffraction-limited imaging in the visible on a 5m t…
10 New Very Low Mass Close Binaries Resolved in the Visible
Nicholas M. Law, Simon T. Hodgkin, Craig D. Mackay +1
We present preliminary results from the first part of the LuckyCam late M-dwarf binarity survey. We survey a sample of 48 nearby (40 pc) and red (M5-M9) stars with the novel hig…
Lucky Imaging: High Angular Resolution Imaging in the Visible from the Ground
Nicholas M. Law, Craig D. Mackay, John E. Baldwin
We use a Lucky Imaging system to obtain I-band images with much improved angular resolution on a ground-based 2.5m telescope. We present results from a 10-night assessment campaign…
CIRPASS: description, performance and astronomical results
Ian Parry, Andrew Bunker, Andrew Dean +9
The Cambridge Infra-red Panoramic Survey Spectrograph (CIRPASS) is described. This near-infrared (NIR) spectrograph has been used on the 8m Gemini-South Telescope, the 3.9m Anglo-A…
The Las Campanas IR Survey. II. Photometric redshifts, comparison with models and clustering evolution
A. E. Firth, R. S. Somerville, R. G. McMahon +15
The LCIR Survey, using the Cambridge IR Survey Instrument (CIRSI), reaches H \~ 20-21 over ~1 deg^2. We present results for 744 arcmin^2 in which public UBVRI data exist. We compar…
Sub-electron read noise at MHz pixel rates
C. D. Mackay, R. N. Tubbs, R. Bell +2
A radically new CCD development by Marconi Applied Technologies has enabled substantial internal gain within the CCD before the signal reaches the output amplifier. With reasonably…
Infrared observations of gravitational lensing in Abell 2219 with CIRSI
Meghan E. Gray, Richard S. Ellis, Alexandre Refregier +5
We present the first detection of a gravitational depletion signal at near-infrared wavelengths, based on deep panoramic images of the cluster Abell 2219 (z=0.22) taken with the Ca…
Optical structure and polarization of the western hot spot of Pictor A
R. C. Thomson, P. Crane, C. D. Mackay
HST images of the western hot spot of the nearby FRII radio galaxy Pictor A resolve the hot spot into an amorphous region of highly polarized wisps. The high polarization (>~ 50%)…
