The Relationship Between Solar Radio and Hard X-ray Emission View all abstracts by submitter

This review discusses the complementary relationship between radio and hardX-ray observations of the Sun using primarily results from the era of theReuven Ramaty High Energy Solar Spectroscopic Imager satellite. A primary focusof joint radio and hard X-ray studies of solar flares uses observations ofnonthermal gyrosynchrotron emission at radio wavelengths and bremsstrahlunghard X-rays to study the properties of electrons accelerated in the main flaresite, since it is well established that these two emissions show very similartemporal behavior. A quantitative prescription is given for comparing theelectron energy distributions derived separately from the two wavelengthranges: this is an important application with the potential for measuring themagnetic field strength in the flaring region, and reveals significantdifferences between the electrons in different energy ranges. Examples of theuse of simultaneous data from the two wavelength ranges to derive physicalconditions are then discussed, including the case of microflares, and thecomparison of images at radio and hard X-ray wavelengths is presented. Therehave been puzzling results obtained from observations of solar flares atmillimeter and submillimeter wavelengths, and the comparison of these resultswith corresponding hard X-ray data is presented. Finally, the review discussesthe association of hard X-ray releases with radio emission at decimeter andmeter wavelengths, which is dominated by plasma emission (at lower frequencies)and electron cyclotron maser emission (at higher frequencies), both coherentemission mechanisms that require small numbers of energetic electrons. Thesecomparisons show broad general associations but detailed correspondence remainsmore elusive.
