Special Issue Information
Dear Colleagues,
Symmetry has played an important role in the formulation of modern physics. Although a generic gravitating system possesses no symmetry, some asymptotic symmetry groups live on the boundaries of asymptotically flat spacetimes. Those intimately related to gravitational waves are the celebrated Bondi–Metzner–Sachs groups and their extensions at null infinities. An infinite number of Noether charges of symmetry groups have been defined, and their conservation laws constrain several physical processes, including gravitational memory effects and gravitational scattering. Asymptotic symmetry, the gravitational memory effect, and soft theorem are three corners of the infrared triangle, a universal triangular equivalence relation echoing in many physical systems with a variety of gauge symmetries. Gravitational scattering processes plant soft hairs on black holes, which has prompted studies on the symmetries of black hole horizons and, more generally, the null boundary of some finite region of spacetime. Through existing and future gravitational wave detectors (such as ground-based and space-borne interferometers, pulsar timing arrays, and the Gaia mission), a gravitational wave memory effect might be observed soon.
The purpose of this Special Issue is to review what has been accomplished, discuss what is to be solved, and examine the future. It thus serves as a forum for fostering new directions and new collaborations among groups of researchers. We invite original or review papers on topics including but not limited to (1) asymptotic symmetries; (2) gravitational memory effects; (3) infrared triangles; (4) celestial holography; (5) black holes; and (6) the detection of gravitational memory effects.

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. 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 2400 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.
