Special Issue Information
Dear Colleagues,
The accurate determination of cosmological parameters, thanks to the observations on the cosmic microwave background provided by the WMAP and Planck satellites, establishes very convincing evidence for the homogeneity and the flatness of the present universe. Cosmic inflation not only offers an interpretation of the features above but also provides a mechanism for the generation of the primordial fluctuations, which seed the observed structure of the universe. Its implementation within a concrete particle physics framework represents an are(n)a of intense theoretical activity. On the other hand, supersymmetry—although undiscovered yet in LHC—remains one of the most plausible, well-motivated, and natural candidates for the evolution of particle physics beyond the Standard Model. Given that inflation takes place at values for the employed scalar field (named inflation) close to the Planck scale, the extension of supersymmetry to include gravity, called supergravity, is particularly convenient for the development of inflation. In this context, the geometry of the moduli space plays a crucial role in achieving a flat enough inflationary potential.
The aim of this Special Issue is to review models of inflation based on supergravity, paying particular attention to their predictions and their intersections with other sectors of relevant research such as supersymmetry breaking and spectroscopy, dark matter, cosmological defects, and baryogenesis via leptogenesis.

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.
