Abstract: 

NRAO operates four forefront radio astronomical facilities that can be applied to a very wide range of forefront scientific problems by the international astronomy community.  The Megamaser Cosmology Project and a number of key science projects, including NANOGrav, will be presented as illustrations.  The newest facility, the international ALMA, will be described in some detail, along with recent observations demonstrating its transformational capabilities.

Host:  Jacqueline Hewitt
