Special Issue "Astrophysical Tests of Modifications to the Symmetry of Special Relativity"
Deadline for manuscript submissions: 31 August 2020.
The continuously increasing quantity of experimental data from cosmic messengers (gamma rays, cosmic rays, neutrinos, joined now by gravitational waves) that has become available in recent times, has allowed us to test deviations from special relativity at very high energies, as a possible phenomenological consequence of quantum gravity.
From the theory side, there are two different scenarios: a violation versus a deformation of special relativity. These scenarios produce different predictions with respect to the type and the magnitude of the possible effects: modification in particle reaction thresholds, new energy loss mechanisms, time delays in the propagation over cosmic distances, etc.
From the experimental side, the situation is rather intriguing, with a possible cutoff in the cosmic neutrino spectrum that could be explained by unstable neutrinos, or the strong bounds in photon time delays that are been recently challenged by the new analysis of a number of gamma ray bursts. The confirmation of the GZK cutoff of cosmic rays, which is a direct consequence of special relativity, also contains subtleties that are being examined at the moment. Finally, the detection of gravitational waves has provided the opportunity to search for modifications to special relativity in a new type of messenger and has also originated the beginning of a real multi-messenger astronomy.
In this Special Issue on the astrophysical tests of modifications to the symmetry of special relativity we welcome contributions on both theoretical and experimental aspects in this rapidly evolving field.

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 papers will be 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. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). 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.
