The Geometry of Gravitational Radiation
Jelle Hartong
We consider 4-dimensional asymptotically flat vacuum spacetimes near future null infinity endowed with the most general allowable Carroll geometry. We show that the near-boundary r…
The Energy-Momentum-News Complex near Future Null Infinity
Jelle Hartong, Emil Have, Vijay Nenmeli +1
We study asymptotically flat vacuum solutions of general relativity in three and four dimensions, with an emphasis on the geometric structures that emerge near null infinity. We co…
Boundary Energy-Momentum Tensors for Asymptotically Flat Spacetimes
Jelle Hartong, Emil Have, Vijay Nenmeli +1
We consider 3D and 4D asymptotically flat spacetimes near future null infinity endowed with the most general allowed Carroll geometry. We define a boundary energy-momentum tensor b…
Fractons on curved spacetime in dimensions
Jelle Hartong, Giandomenico Palumbo, Simon Pekar +2
We study dipole Chern-Simons theory with and without a cosmological constant in dimensions. We write the theory in a second order formulation and show that this leads to a fr…
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…
Strings near black holes are Carrollian -- Part II
Arjun Bagchi, Aritra Banerjee, Jelle Hartong +2
We study classical closed bosonic strings probing the near-horizon region of a non-extremal black hole and show that this corresponds to understanding string theory in the Carroll…
