The ngVLA: A technical development update

The National Radio Astronomy Observatory (NRAO) has engaged the broad scientific and technical communities in the design of a next-generation Very Large Array (ngVLA), a large-scale research infrastructure project under development for the National Science Foundation Astronomical Sciences Division (NSF-AST) through a cooperative agreement with Associated Universities, Inc. The ngVLA is 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.
