21st NRAO Synthesis Imaging Workshop

NMT, Socorro, New Mexico
May 26 - June 3, 2026

The NRAO is preparing to host the 21st Synthesis Imaging Summer Workshop in Socorro, New Mexico, from 26 May to 3rd June 2026. The workshop will consist of a week of lectures on aperture synthesis theory and techniques at a level appropriate for graduate students in astrophysics, covering both radio interferometry fundamentals and state-of-the-art methods and techniques. The program will also include discussion groups, and tutorials demonstrating data collection, calibration, and imaging of various types of observations, including new data from the Very Large Array (VLA), Very Long Baseline Array (VLBA), and the Atacama Large Millimeter/submillimeter Array (ALMA), and a special tour to the VLA site.

Registration deadline is April 30, 2026, or when the 150-participant capacity of the workshop is reached.

For more details for this event, and to register, please visit the official 21st NRAO Synthesis Imaging Workshop website.

The NSF National Radio Astronomy Observatory and NSF Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NSF NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NSF NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NSF NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NSF NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The U.S. National Science Foundation (U.S. NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."
