VERY SMALL ARRAY: OBSERVATIONS AND LATEST RESULTS

The Very Small Array is an interferometric telescope operating at 33 GHz at Tenerife. It has the flexibility to measure fluctuations in the Cosmic Microwave Background over a large range of angular scales corresponding to l=150-2500. This range of angular scales is achieved by means of three configurations of the main array: compact, extended and super-extended. We also employ a dedicated source-subtraction single baseline interferometer to allow subtraction of discrete sources, the dominant foreground on these angular scales. Here we present the latest results from observations with the extended array covering angular scales between l=150-1500. The observing strategy and data analysis pipeline are summarised. We present new VSA maps and the latest power spectrum from the VSA collaboration.
