Solar radio astronomy is a burgeoning field affecting almost all branches of solar physics, space weather, and even other branches of astrophysics. Solar radio emissions come not only from various kinds of solar activities, but also from the Sun, from the photosphere, through the chromosphere to the corona, and far into interplanetary space; the related frequency spans more than 5 orders of magnitude from several hundreds of GHz (sub-mm wavelength) down to sub-MHz (km wavelength). Radio emissions are very sensitive to the acceleration and propagation of nonthermal electrons, plasma instabilities, magnetic fields and their variations, magnetic reconnections and violent energy releases, various scales of shock waves, etc. Solar radio observations can possibly be applied to measure the magnetic fields in the very hot and diluted coronal atmosphere, to reveal the mystery of coronal heating, to detect energetic particle acceleration and propagation, to explore the origin of solar violent eruptions (including solar flares, CMEs, various scales of jets, etc.) and track their temporal and spatial evolutions, and to provide crucial information for predicting space weather.
Recently, a series of advanced solar radio telescopes were put into operation and obtained a large amount of observation data. These new instruments include MUSER, EVOSA, SRH, LOFAR, MWA, ALMA and PSP. Through their high-sensitivity and high-resolution solar radio observations, we have the opportunity to give new explanations to the above important problems, discover new physics knowledge and make new scientific breakthroughs. In order to exhibit the new, up-to-date progress obtained in this domain, we are organizing the Special Issue, “Solar Radio Emissions”, and invite colleagues to submit their new manuscripts on one or more of the following topics for this Special Issue:
- New observational phenomena of solar radio emissions;
- New discoveries of spectral fine structures of solar radio bursts;
- New theoretical explanations of solar radio bursts, including an explanation of the origin and formation mechanism of the solar radio Zebra pattern, fiber bursts, spike groups, the fine structures of type II, III, and IV bursts, and multi-timescale QPP;
- Radio signals of magnetic reconnections and shock waves;
- Radio precursors of solar flares and CMEs;
- Diagnostics of coronal magnetic fields from radio emissions;
- Radio emissions related to particle acceleration and propagations;
- Advanced methods to predict solar activities and space weather by using solar radio observations;
- Possible clues for new physics knowledge hidden by solar radio emissions, such as signals for dark matter, solar interior structures and dynamics, etc.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
