An online workshop held on January 19-20, 2022. The program and talk recordings can be found here. Slides are being collected here.
Please feel free to send your feedback, suggestions, ideas, and any thoughts on the DSA-2000 conceptual design and science case via e-mail to science [at] deepsynoptic.org.
The DSA-2000 is designed to be a world-leading radio survey telescope that is in its design phase, slated for construction in the middle of this decade. The telescope will consist of 2,000 5-m dishes operating between 0.7-2 GHz, with comparable sensitivity to and survey speed in excess of 6x that of SKA1-mid. The telescope 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.
Through a series of invited talks and associated discussions, this open workshop is intended to engage a diverse community in identifying and elucidating some of the most exciting science that the DSA-2000 will enable. At the same time, the workshop begins the process of ensuring that the requirements of these science programs are matched by the DSA-2000 design. The project will undergo a conceptual design review shortly after this workshop. The workshop will lead to a summary paper that links the preliminary science case to the conceptual telescope design. Future workshops will enable a more detailed science case and science traceability matrix to be developed, including early science opportunities during construction. Finally, the workshop is also intended to ensure that effective strategies for enabling broader impacts, and presenting data to the public, are central to the DSA-2000 design from this early stage.
We look forward to seeing you there!
The workshop will be held over two sessions (1500-1800 UT) on January 19th and 20th, 2022. All links (Zoom, Slack invite) will be sent a few days prior to the workshop to all registered attendees. For any questions, please contact Vikram Ravi (vikram [at] caltech [dot] edu).
