The ngVLA: Reference design update

Abstract

The ngVLA is envisaged as an interferometric array with ten times greater sensitivity and spatial resolution than the current VLA and ALMA, operating in the frequency range of 1.2 – 116 GHz. In this talk we provide a project status update and overview of the Reference Design. The Reference Design is a low-technical-risk, costed concept that supports the key science goals for the facility, and forms the technical and cost basis of the ngVLA Astro2020 Decadal Survey proposal.
