Classical and Quantum Gravity welcomes original research articles on all branches of gravitational physics and the theory of spacetime. The readership of the journal is broad, comprising gravitational theorists and experimentalists in physics, mathematics and cosmology. All articles should be of interest to this broad readership and should contain a summary that places the findings in the wider context of gravitational physics.

The detailed coverage of the journal includes, but is not limited to:

Classical general relativity

All aspects including initial-value problems, techniques and applications of numerical relativity, exact solutions, topology and causal structure, singularities, canonical and other formalisms, Regge calculus, twistors, dynamical triangulation and other simulation methods. Exact Solutions policy.

Applications of relativity

including relativistic astrophysics, gravitational radiation, gravitational lenses, black holes and collapsed objects, and physical processes in their vicinity.

Experimental gravitation

including gravitational wave detection, tests of gravitational theories, and articles on data analysis and instrumentation with a clear relevance to gravitation. Further details.

Cosmology and the early universe

including particle physics, grand unified theories and phase transitions, inflationary cosmology, theories of galaxy formation and large-scale structure, cosmic microwave background radiation, cosmic strings and topological defects, and cosmic topology.

Quantum gravity

All aspects including canonical and covariant quantization, quantum field theory in curved spacetime, semiclassical quantization, topological effects, gauge and gravitational anomalies, quantum cosmology and the quantum theory of black holes and information loss.

Supergravity, superstrings and supersymmetry

including the structure of string theory, M-theory and its ramifications, conformal field theory, worldsheet symmetries, string vacua, compactifications and phenomenological applications, p-brane dynamics, nonperturbative aspects of string theory and M-theory.

Mathematical physics

relevant to gravitation, specifically gauge-covariant systems, strings and extended objects, constrained Hamiltonian systems, BRST quantization, geometric quantization, renormalization, path integrals, geometry and topology of field theories, instantons and non-linear sigma models, and differential geometry relevant to gravitation.

The journal publishes the following types of articles:

Research papers

Reports of original research work; not normally more than 8500 words (14 journal pages).

Fast track communications

Short, timely papers presenting important new developments. Fast Track Communications (FTCs) have a strict length limit of 8 journal pages (5000 words) and are given prime importance in the journal. Authors submitting an FTC should accompany their manuscript with a short statement outlining why they believe the work to merit high-priority publication.

Topical reviews

Comprehensive review articles commissioned by the Editorial Board.

Brief reviews

Short review articles reviewing rapid, recent progress commissioned by the Editorial Board.

Comments

Brief articles that comment on a previously published Classical and Quantum Gravity article. The authors of the criticised paper may be invited to submit a Reply in response. Comments and Replies are not normally longer than 2500 words each.

Notes

Brief articles that make a short, interesting point, which would not normally merit publication as a full Paper but still make a useful and novel addition to the literature. They may highlight an interesting point, clarify a common misunderstanding or confusion, or present a short new result. Unlike Comments, they do not relate to a specific published article. Notes are not normally longer than 2500 words.
