We report progress in commissioning the Expanded Very Large Array (EVLA), a project to improve the key observational capabilities of the VLA (point source sensitivity, instantaneous bandwidth, frequency resolution, and flexibility) by roughly an order of magnitude, while extending the suite of receivers to allow tuning the array anywhere between 1 and 50 GHz. The first scientific data were taken on March 2, 2010, and commissioning and scientific operations continue at a rapid pace. Here we report on the status of the upgrades and present some recent observational results. We also review the schedule through the end of the construction/commissioning period with special emphasis on the scientific capabilities we expect to offer the community. Full operations are scheduled to begin at the end of 2012.
The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
