New Frontiers in Astroparticle Physics: From Nuclear Reactions to Multimessenger Astronomy

Dear Colleagues,

Recent observations have opened completely new perspectives in the way we look at the Universe and the tools we can use to comprehend it. For the first time, the same source has been detected by means of both gravitational and electromagnetic waves, and this implies that now, objects of astrophysical interest can be observed in a much more complete way than before. This is indeed the start of a new era, meaning that the means and techniques of investigation will be qualitatively different from before. In this perspective, bringing together expertise from different fields in astroparticle physics is of paramount importance. In addition to the ones cited, there are many other topics considered to have the most comprehensive view of the field. For instance, in this context, a detailed understanding of the complex nuclear reactions taking place in the cores of massive objects is quite important, and for this, the study of the relative cross-sections performed at heavy ion accelerators can be helpful. Moreover, the constant search for candidates for dark matter and dark energy could provide an additional piece to this mosaic and complete the view we have of the Universe. Furthermore, the development of new detection systems, and the possibility to compare different kinds of data, obtained using various techniques, opens the way to multimessenger astronomy, which actually represents one of the most interesting frontiers in astroparticle physics. We believe that this is the right moment to provide a state-of-the-art summary of all most recent discoveries and developments, making an effort to combine the information coming from different fields and techniques of investigation. Contributions are expected to address, but are not limited to, the following areas:

• Multimessenger astronomy;
• Gravitational waves;
• Nuclear reactions of astrophysical interest;
• Astroparticle physics;
• Detection techniques for astroparticle physics;
• Dark matter and dark energy.

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.
