A blind detection of a large, complex, Sunyaev--Zel'dovich structure
AMI Consortium, :, T. W. Shimwell +58
We present an interesting Sunyaev-Zel'dovich (SZ) detection in the first of the Arcminute Microkelvin Imager (AMI) 'blind', degree-square fields to have been observed down to our t…
The brighter-fatter effect and pixel correlations in CCD sensors
P. Antilogus, P. Astier, P. Doherty +2
We present evidence that spots imaged using astronomical CCDs do not exactly scale with flux: bright spots tend to be broader than faint ones, using the same illumination pattern.…
The Arcminute Microkelvin Imager
AMI Consortium, :, J. T. L. Zwart +57
The Arcminute Microkelvin Imager is a pair of interferometer arrays operating with six frequency channels spanning 13.9-18.2 GHz, with very high sensitivity to angular scales 30''-…
The Pan-STARRS1 Photometric System
J. L. Tonry, C. W. Stubbs, K. R. Lykke +11
The Pan-STARRS1 survey is collecting multi-epoch, multi-color observations of the sky north of declination -30 deg to unprecedented depths. These data are being photometrically and…
High-significance Sunyaev-Zel'dovich measurement: Abell 1914 seen with the Arcminute Microkelvin Imager
AMI Collaboration, R. Barker, P. Biddulph +47
We report the first detection of a Sunyaev-Zel'dovich (S-Z) decrement with the Arcminute Microkelvin Imager (AMI). We have made commissioning observations towards the cluster A1914…
An ultra-wide bandwidth (704 to 4032 MHz) receiver for the Parkes radio telescope
G. Hobbs, R. N. Manchester, A. Dunning +69
We describe an ultra-wide-bandwidth, low-frequency receiver ("UWL") recently installed on the Parkes radio telescope. The receiver system provides continuous frequency coverage fro…
