Non-Inertial Frames and Dirac Observables in Relativity
TL;DR: In this article, the transition between one non-inertial frame and another is a gauge transformation, extra variables describing the frame are gauge variables, and the measureable matter quantities are gauge invariant Dirac observables.

The quantization of gravity - an introduction
TL;DR: The conceptual and technical problems of both approaches are discussed, and a discussion of evidence for quantum gravity from the rest of physics is discussed in this paper, which assumes some familiarity with non-relativistic quantum mechanics, special relativity, and the Lagrangian and Hamiltonian formulations of classical mechanics; some experience with classical field theory, quantum electrodynamics and the gauge principle in electromagnetism might be helpful but is not required.

Asymptotic Flatness, Taub-NUT, and Variational Principle
TL;DR: Using hyperbolic temporal and spatial cutoffs to define four-dimensional asymptotically flat spacetimes, this article showed that supertranslation ambiguities in the Asymptotic fields can all be removed even in the presence of gravitational magnetic charges and that configurations with different electric and magnetic fourmomenta can be consistently considered in the Mann-Marolf variational principle.

Canonical Gravity and Relativistic Metrology: from Clock Synchronization to Dark Matter as a Relativistic Inertial Effect
TL;DR: In this paper, it was shown that the main signatures for the existence of dark matter can be reinterpreted as an relativistic inertial effect induced by the non-Euclidean 3-spaces.
