Cosmological parameter estimation and Bayesian model comparison using VSA data
Anze Slosar, Pedro Carreira, Kieran Cleary +28
We constrain the basic comological parameters using the first observations by the Very Small Array (VSA) in its extended configuration, together with existing cosmic microwave back…
The CMB power spectrum out to l=1400 measured by the VSA
Keith Grainge, Pedro Carreira, Kieran Cleary +28
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…
Constraining the shape of the CMB: a Peak-by-Peak analysis
Carolina J. Odman, Alessandro Melchiorri, Michael P. Hobson +1
The recent measurements of the power spectrum of Cosmic Microwave Background anisotropies are consistent with the simplest inflationary scenario and big bang nucleosynthesis constr…
First results from the Very Small Array -- II. Observations of the CMB
Angela C. Taylor, Pedro Carreira, Kieran Cleary +24
We have observed the cosmic microwave background temperature fluctuations in eight fields covering three separated areas of sky with the Very Small Array at 34 GHz. A total area of…
First results from the Very Small Array -- III. The CMB power spectrum
Paul F. Scott, Pedro Carreira, Kieran Cleary +23
We present the power spectrum of the fluctuations in the cosmic microwave background detected by the Very Small Array (VSA) in its first season of observations in its compact confi…
First results from the Very Small Array -- I. Observational methods
Robert A. Watson, Pedro Carreira, Kieran Cleary +23
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 d…
