Point particles in general relativity: beyond linear perturbation theory
Jørgen Musaeus, Adam Pound, Samuel D. Upton
Point particles are generically ill defined in fully nonlinear general relativity, although they are naturally well defined in linear perturbation theory. In a previous paper, two…
Galilean fluids from non-relativistic gravity
Jelle Hartong, Aditya Mehra, Jørgen Musaeus
The -expansion of general relativity appropriately sourced by matter can be used to derive an action principle for Newtonian gravity. The gravitational part of this action is…
Setting the connection free in the Galilei and Carroll expansions of gravity
Jørgen Musaeus, Niels A. Obers, Gerben Oling
We obtain a Palatini-type formulation for the Galilei and Carroll expansions of general relativity, where the connection is promoted to a variable. Known versions of these large an…
Towards a covariant framework for post-Newtonian expansions for radiative sources
Jelle Hartong, Jørgen Musaeus
We consider the classic problem of a compact fluid source that behaves non-relativistically and that radiates gravitational waves. The problem consists of determining the metric cl…
Fractons, dipole symmetries and curved spacetime
Leo Bidussi, Jelle Hartong, Emil Have +2
We study complex scalar theories with dipole symmetry and uncover a no-go theorem that governs the structure of such theories and which, in particular, reveals that a Gaussian theo…
