Special Issue "Gravitational Waves"
A special issue of Symmetry (ISSN 2073-8994).
Deadline for manuscript submissions: closed (30 September 2018)
Direct observation of gravitational waves in 2015 marked the beginning of a new era in physics and astronomy. Objects in the sky, such as binary black holes, which are not visible in conventional electromagnetic spectrum, have recently been observed via gravitational waves that they emit during the merger phase. Other objects, such as binary neutron stars, can produce both electromagnetic and gravitational-wave signals, which can be analyzed concurrently, leading to an entirely new way to study the universe.
Gravitational waves are minute perturbations of the geometry of space-time which propagate through space with the speed of light. To describe the propagation of gravitational waves and their effect on the detector one has to choose a certain coordinate system. One of the most frequently used coordinate systems is associated with the transverse and traceless gauge in which the gravitational wave is represented by a symmetric, transverse and traceless tensor of the metric perturbation. Gravitational waves can also be described in the Fermi normal coordinate system which is built around the worldline of inertial observer. Other coordinate systems may be more suitable for the analysis of gravitational waves because of the symmetries they manifest.
In this Special Issues of Symmetry, we focus our attention on the role of the coordinate system in the description of gravitational waves, their interaction with the detector, and the formation of the signal. We welcome papers that present theoretical analysis of gravitational waves when described in different coordinate systems and provide physical interpretation of the properties of these coordinate systems. In particular, the authors are welcome to analyze the motion of test masses under the influence of gravitational waves in these coordinate systems, or the way these coordinates affect our interpretation of the detection method.

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.
