Thanks to its proximity, the Sun, our nearest star, serves as an outstanding laboratory for studying a variety of high-energy astrophysical processes. Such processes include particle acceleration and intense plasma heating driven by magnetic reconnection, turbulence, and shocks. Radio observations offer unique diagnostics for the energetic electrons and the plasma environment in which they are produced, particularly when the emission is spatially, spectrally, and temporally resolved. In the past decade, we have been enjoying a major transition in solar radio astronomy as it evolves from imaging at a few discrete frequencies to true imaging spectroscopy over a wide frequency range at a fast time cadence, known as "broadband dynamic imaging spectroscopy". In this talk, I will highlight our recent results based on this technique, enabled by observations from the Karl G. Jansky Very Large Array (VLA) and NJIT's Expanded Owens Valley Solar Array (EOVSA).
Dr. Bin Chen (陈彬) is an associate professor in the Department of Physics and the Center for Solar-Terrestrial Research at the New Jersey Institute of Technology (NJIT). Before that, he held an appointment as an astrophysicist at the Harvard-Smithsonian Center for Astrophysics. He obtained his B.Sc. from Peking University in 2005, an M.Sc. from NAOC/UCAS in 2008, and a Ph.D. from the University of Virginia in 2013. He is a recipient of the US National Science Foundation (NSF) CAREER Award (2017) and the NASA/UCAR Jack Eddy Fellowship (2013). In 2019, he was elected as a committee member of the Solar Physics Division of the American Astronomical Society (AAS/SPD). Chen's research mainly focuses on solar high-energy phenomena using radio and multi-wavelength observations. For more information about him, please visit: https://web.njit.edu/~binchen/
