Contributions to Astro2020

Astro2020 is the Astronomy and Astrophysics Decadal Survey; a community partnership with the National Academies to identify key prorities in the astrophysical field. The goal of Astro2020 is to provide a comprehensive strategy for investiments in research for the upcoming decade. Documented below are the contributing white papers by the NANOGrav collaboration for the 2020-2030 decade. For more information on Astro2020, visit the partnership's website located here.
