Special Issue Information
Dear Colleagues,
Currently, supernovae (SNe) observations and research are booming. The number of SNe candidates increased ten times in the past decade, and the number of well-observed and studied samples has also sharply increased. Now, the statistical gain from increasing numbers of samples of regular-type supernovae appears to be tapering off. However, we are observing an expansion of the parameters of SNe in the new generation of blinded, high-cadence, and multi-color surveys. In addition, an increasing number of rare events are appearing, including super-luminous or extra-faint objects, fast- or slow-rising events, and cases with signatures of interaction, suggesting a complex evolution at the late age of their progenitor. Thus, observations of even a single supernova can still yield huge scientific gains in the future. Moreover, new statistical tools also provide new methods through which distinct insights into supernova natures can be obtained.
To clarify the origin of SNe diversity and constrain the connection between supernova properties and progenitor parameters, we need to obtain multi-band information concerning these explosions. For example, the shock waves and ejected matter produced by a supernova explosion usually interact with the matter of the progenitor star, thereby changing the shape of the supernova and producing different and even rare observational features in the X-ray ultraviolet optical and radio wavelengths. Thus, multi-band observation has further promoted the study of supernovae. Furthermore, in the multi-messenger age, new observation methods such as gravitational waves and neutrinos combined with traditional electromagnetic observation will create a completely different scene in supernova observation and research.
The established observational diversities of SNe provide a new way to constrain the connection between supernova properties and progenitor parameters and introduce new challenges for the SN explosion model. Given the unique opportunities and challenges, this Special Issue aims to collect recent breakthroughs and insights in SN observation and research, including observations of particular and exciting events, statistical research and insights based on large samples, new modeling or statistical methods, new survey technologies and strategies, multi-messenger observations, the origin of observational diversities, and the relationship between observational diversities and progenitor properties.

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.
