Computational Physics, Inc., seeks a radio astronomer with experience in interferometry to join our team at the United States Naval Observatory (USNO) in Washington, D.C.
The USNO is responsible for the production and dissemination of precise parameters concerning time, star positions, and the earth’s rotation. These astronomical and geophysical parameters support navigation (GPS) and many other applications. This USNO mission includes maintaining, together with the Paris Observatory, the International Celestial Reference System (ICRS) and the International Celestial Reference Frame (ICRF).
DESCRIPTION OF THE POSITION
The focus of this position will be to provide radio frequency images of International Celestial Reference Frame (ICRF) sources, intrinsic structure models derived from the radio images, and an assessment of the astrometric quality of the ICRF sources, based on their intrinsic structure, to support definition and maintenance of the celestial reference frame. Work includes the maintenance of a Web-accessible data archive (Fundamental Reference Image Data Archive, or FRIDA) of radio frequency images of ICRF sources, derived from observations executed using radio astronomy telescopes, especially the Very Long Baseline Array (VLBA). The work includes the correlation and calibration of imaging data and the publication of the data to FRIDA. Ultimately, this effort will require incorporating data on reference frame sources at multiple wavelengths in the future. A small amount of travel may be required.
PhD with at least 3 years’ experience in radio interferometry is required.
Experience in the collection, processing and analysis of astronomical data taken in the radio portion of the spectrum is required.
Specific experience with the VLBA and the supporting software and data processing systems is highly desirable.
Experience in the use of radio astronomy to support celestial reference frame or geodesy observations is desirable.
U.S. citizenship is required by our contract from the Navy.
The USNO requires full vaccination for Covid-19.
