Dale Gary Colloquium: Recent Advances in Solar Radio Imaging Spectroscopy

Online

Abstract

An impressive number of new radio instruments have appeared on the scene, or are in the planning stages, that perform high-resolution imaging at many closely spaced frequencies over a broad frequency range. In the case of imaging of the Sun, this has ushered in a revolution in our understanding by providing radio imaging spectroscopy, i.e., spatially resolved brightness temperature spectra. Such spectra can be connected directly to basic physical parameters of the radiating particles and their environment, leading to a breakthrough in our understanding of solar flares and bursts as well as the structure and processes of the non-flaring solar atmosphere. This talk will cover the instruments and advances fueling this revolution, and present some of the recent results for the Sun and also (briefly) stars.
