General Relativity and Gravitation is a journal devoted to all aspects of modern gravitational science, and published under the auspices of the International Society on General Relativity and Gravitation.It welcomes in particular original articles on the following topics of current research:Analytical general relativity, including its interface with geometrical analysisNumerical relativityTheoretical and observational cosmologyRelativistic astrophysicsGravitational waves: data analysis, astrophysical sources and detector scienceExtensions of general relativitySupergravityGravitational aspects of string theory and its extensionsQuantum gravity: canonical approaches, in particular loop quantum gravity, and path integral approaches, in particular spin foams, Regge calculus and dynamical triangulationsQuantum field theory in curved spacetimeNon-commutative geometry and gravitationExperimental gravity, in particular tests of general relativityThe journal publishes articles on all theoretical and experimental aspects of modern general relativity and gravitation, as well as book reviews and historical articles of special interest.
