The Frequency Agile Solar Radiotelescope: On the Cusp of the Future


Prof. Dale Gary, NJIT

Room: 373 Tiernan

Time: Noon-1 pm with 11:30 am tea time



The Frequency Agile Solar Radiotelescope (FASR) is a concept for a modern solar-dedicated radio array that has been under intense study for more than 12 years, since the first science workshop held in 1995.  It is finally on the verge of becoming a reality.  The science motivation for the facility is discussed through examples from fore-runner instruments such as NJIT's Owens Valley Solar Array, the NRAO Very Large Array, the Japan's Nobeyama Radioheliograph, among others.  The exciting science that the completed FASR will do, and its prospects for new discoveries, is briefly discussed, with emphasis on the basic physics
questions that will be addressed.  These include the first true measurement of magnetic fields in the solar corona, the direct imaging of sites of magnetic energy release and subsequent acceleration of relativistic electrons, and initiation of eruptions from the Sun that are the drivers of space weather.  The status of the project and NJIT's role is described.
