Special Issue "Numerical Relativity and Gravitational Wave"
Deadline for manuscript submissions: 31 July 2021.
Interests: General Relativity; Numerical Relativity; Gravitational Wave
Numerical relativity (NR) is currently a major topic connecting general relativity to computational astrophysics and simulation science. After the 2006 breakthroughs in the simulation of black hole collisions, the field developed in several directions. Current applications range from multimessenger astrophysics modeling to cosmology, with new formal and numerical aspects under development.
Key astrophysical NR applications involve the simulations of mergers of neutron stars and black holes and of core collapse supernovae. Binary black hole simulations crucially helped the characterization of the first gravitational signals detected by the LIGO-Virgo experiments. Their increasing accuracy and completeness is driving waveform modeling for gravitationalwave astronomy. General relativistic fluidynamics simulations of compact binary mergers are essential to study the engines that power electromagnetic observables. Strong gravity is also a primary component for quantitative simulations of stellar collapse and accretion onto compact objects.
Fundamental applications of NR tools are the dynamical stability of compact objects, scenarios for black hole formation, and investigations of the cosmic censorship conjecture. Critical phenomena in gravitational collapse were a genuine numerical discovery and are currently being extended to nonspherical symmetries and multidimensions. High-energy black-hole collisions can be used to probe black-hole formation in proton–proton collisions at particle colliders or in cosmic-ray showers hitting the Earth’s atmosphere. The field is evolving also towards the exploration of alternative theories of gravity, black-hole studies in the context of the gauge–gravity duality, and the first cosmological applications.
The purpose of this Special Issue is to collect new original contributions in the broad field of numerical relativity. We welcome contributions exploring new formalisms and new numerical methods for Einstein equations, as well as new applications of NR methods in all areas.

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 1800 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.
