Non-Gaussianity in the Very Small Array CMB maps with Smooth-Goodness-of-fit tests (2006)
Rubino-Martin, Jose Alberto, Aliaga, Antonio M., Barreiro, R. B., Battye, Richard A., Carreira, Pedro, Cleary, Kieran, ...
(Abridged) We have used the Rayner & Best (1989) smooth tests of goodness-of-fit to study the Gaussianity of the Very Small Array (VSA) data. Out of the 41 published VSA individual pointings...
Source subtraction for the extended Very Small Array and 33-GHz source count estimates (2004)
Cleary, Kieran A., Taylor, Angela C., Waldram, Elizabeth, Battye, Richard A., Dickinson, Clive, Davies, Rod D., ...
We describe the source subtraction strategy and observations for the extended Very Small Array, a CMB interferometer operating at 33 GHz. A total of 453 sources were monitored at 33 GHz using a...
High sensitivity measurements of the CMB power spectrum with the extended Very Small Array (2004)
Dickinson, Clive, Battye, Richard A., Cleary, Kieran, Davies, Rod D., Davis, Richard J., Genova-Santos, Ricardo, ...
We present deep Ka-band ($\nu \approx 33$ GHz) observations of the CMB made with the extended Very Small Array (VSA). This configuration produces a naturally weighted synthesized FWHM beamwidth of...
Cosmological parameter estimation using Very Small Array data out to l=1500 (2004)
Rebolo, Rafael, Battye, Richard A., Carreira, Pedro, Cleary, Kieran, Davies, Rod D., Davis, Richard J., ...
We estimate cosmological parameters using data obtained by the Very Small Array (VSA) in its extended configuration, in conjunction with a variety of other CMB data and external priors. Within the...
Estimating the bispectrum of the Very Small Array data (2004)
Smith, Sarah, Rocha, Graca, Challinor, Anthony, Battye, Richard A., Carreira, Pedro, Cleary, Kieran, ...
We estimate the bispectrum of the Very Small Array data from the compact and extended configuration observations released in December 2002, and compare our results to those obtained from Gaussian...
Searching for non-Gaussianity in the VSA data (2003)
Savage, Richard, Battye, Richard A., Carreira, Pedro, Cleary, Kieran, Davies, Rod D., Davis, Richard J., ...
We have tested Very Small Array (VSA) observations of three regions of sky for the presence of non-Gaussianity, using high-order cumulants, Minkowski functionals, a wavelet-based test and a Bayesian...
The CMB power spectrum out to l=1400 measured by the VSA (2002)
Grainge, Keith, Carreira, Pedro, Cleary, Kieran, Davies, Rod D., Davis, Richard J., Dickinson, Clive, ...
We have observed the cosmic microwave background (CMB) in three regions of sky using the Very Small Array (VSA) in an extended configuration with antennas of beamwidth 2 degrees at 34 GHz. Combined...
Cosmological parameter estimation and Bayesian model comparison using VSA data (2002)

We investigate the constraints on basic cosmological parameters set by the first compact-configuration observations of the Very Small Array (VSA), and other cosmological data sets, in the standard...
First results from the Very Small Array -- I. Observational methods (2002)
Watson, Robert A., Carreira, Pedro, Cleary, Kieran, Davies, Rod D., Davis, Richard J., Dickinson, Clive, ...
The Very Small Array (VSA) is a synthesis telescope designed to image faint structures in the cosmic microwave background on degree and sub-degree angular scales. The VSA has key differences from...
