ngVLA Community Studies Program
As part of the process of building towards a final concept for the ngVLA, NRAO launched the ngVLA Community Studies program in 2016, allowing members of the scientific and engineering communities to become major contributors to this effort. A total of 53 ngVLA Community Studies have been approved since 2016.

Supporting materials for the ngVLA Community Studies, such as notional receiver and array configuration files, can be found on the ngVLA Tools page. All ngVLA Community Studies are expected to:
- demonstrate the major scientific/technical advancement being advocated and put it in context for the broader astronomical community
- clearly state the impact on design choices
- produce a publication in a peer-refereed journal, or at minimum in the ngVLA memo series

Second Round Awards
As part of the process of building a final concept for the ngVLA, NRAO launched the ngVLA Community Studies program in 2016, allowing members of the scientific and engineering communities to become major contributors to this effort. Given the success of our first round of ngVLA Community Studies, a second round was initiated. Aimed at tackling some of the most pressing questions unveiled by the initial studies, the primary objective for the second round of community studies is to further develop the Key Science Goals outlined in Memo #19. Studies and simulations were asked to focus on addressing these key science goals while better quantifying the expected performance of the array in order to provide additional supporting technical requirements. A list of the 12 approved studies from our second round of community studies is provided below. An asterisk denotes proposals that requested and were approved for additional funding.
