This section is working to develop the sensors and techniques required to open a relatively unexplored area of astrophysics: high-resolution, long-wavelength astronomy. We pursue developments in three areas: new technology low frequency ground-based arrays, new concepts for very low frequency space and lunar-based arrays, and new radio frequency excision, ionospheric calibration, and wide-field mapping techniques needed for all low frequency arrays. Work in this section is led by Section Head and Principal Investigator Dr. Namir Kassim.
Distributed across our web pages are graphical illustrations representative of ongoing and past R&D accomplishments of our Section. These include examples of developments in instrumentation, software, and results from our programs in observational astrophysics that extend from low radio frequencies to X-rays and Gamma-rays.
