Abstract: Solar flares involve the catastrophic release of magnetic energy through magnetic reconnection. Flares are also highly efficient particle accelerators, capable of accelerating a significant fraction of available charged particles to relativistic energies within a short time. Radio remote-sensing observations offer unique diagnostics for both the plasma environment at (or near) the magnetic reconnection site and the flare-accelerated high-energy electrons. 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 some of our recent results based on this technique, enabled by observations from the Karl G. Jansky Very Large Array and NJIT's solar-dedicated radio observatory: The Expanded Owens Valley Solar Array.
