Dear Colleagues,

Supernovae mark endpoints of stellar evolution and are observed as powerful explosions. Of the various types of supernovae, Type Ia (SNe Ia) are widely used to measure distances across the universe. They also lead to the discovery of cosmic acceleration. Some other types, such as Type II (SNe II) and SuperLuminous SuperNovae (SLSNe), are becoming promising distance indicators as well.

Currently, cosmology with supernovae are limited mostly by systematic uncertainties in cosmological analysis. A major share of these systematics have astrophysical origin, such as their correlation with their host galaxies, line-of-sight lensing/demagnification effect, and progenitor channel. Current (e.g, Zwicky Transient facility) and future (e.g, Legacy Survey of Space and Time) transient surveys are discovering many supernova candidates. It will be a challenge to properly classify them and use them as cosmological probes. Understanding systematic uncertainties and studying the astrophysics of supernovae has vital importance to achieve precise results in supernova cosmology and to shed light on dark energy—the force responsible for cosmic acceleration.

In this Special Issue of Universe, we will focus on improved methods of supernova classification, follow-up strategies, methods of cosmological analysis, and investigation of systematic uncertainties, progenitor channels, and explosion mechanisms. We plan to include contributions from both theoretical and observational perspectives.

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.
