The DSA-2000 is designed to be a world-leading radio survey telescope that has just passed its Conceptual Design Review (CDR), slated for construction in the middle of this decade. The telescope will consist of 2,000 x 5-m dishes operating between 0.7-2 GHz and will operate as a radio camera, providing the community with images and data cubes rather than visibility data products. The DSA-2000 images will have few-arcsecond resolution, sub-microJansky sensitivity, and dynamic ranges >100,000 across the entire sky. The Radio Camera Initiative is developing the necessary algorithms and software.

The DSA-2000 will address frontier topics in multimessenger astronomy by discovering the afterglows of gravitational-wave events, and by timing a suite of millisecond pulsars to detect and characterize low-frequency gravitational waves from binary supermassive black holes. Through a sixteen-epoch all-sky survey, the DSA-2000 will map, catalog, characterize and monitor over a billion radio sources, with detailed HI observations to z=1. These observations will transform our understanding of fuel and feedback associated with star formation and nuclear accretion in galaxies across cosmic time. Time-domain analyses of DSA-2000 survey data, including commensal searches for FRBs and pulsars, will deliver transformational samples of events that populate the dynamic radio sky.

During this AAS splinter session we will discuss the observatory's design as well as some of the key science that the DSA-2000 will address. The DSA-2000 will also have a booth in the main exhibition hall where additional information will be presented.

We look forward to seeing you there!
