A Multiwavelength View of Supernovae

Dear Colleagues,

Supernovae (SNe) are one of the few objects that are visible over the entire wavelength range. They have been imaged at radio, infra-red, optical, ultraviolet, and X-ray wavelengths, with candidates at gamma-ray wavelengths. The increasing sensitivity of ground-based and space-based telescopes in the last half century has led to a vast increase in both the number of objects detected and our knowledge of these objects. More classes and subclasses of SNe appear to have arisen. Type Ia SNe have acquired a prominent role in cosmology, but their progenitors are still debated. The role of binary stars in SN formation and evolution is being investigated. Improvements in X-ray and radio telescopes have allowed for an investigation of various emission processes that was not possible a few decades ago. Our understanding of their radiation signatures at all wavelengths has significantly increased.

The goal of this Special Issue is to summarize recent multiwavelength results for supernovae. We aim to have papers describing results for individual SNe at various wavelengths, as well as review papers summarizing results at specific wavelengths. We also aim to include a description of theoretical processes, analysis of various emission signatures, and investigations of SN evolution and interactions with the circumstellar medium. Overall, we hope that this Special Issue will encapsulate the current state of SN research, summarize the observational results, and outline the physics necessary to understand the observations.

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.
