The Cosmological Dipole in Tilted Anisotropic Universes
Alicia MartÃn, Constantinos Skordis, Deaglan J. Bartlett +3
There is tentative evidence for a mismatch between the rest frames of matter and the cosmic microwave background, the "quasar dipole anomaly". We consider such a dipole in tilted a…
Khronon-Tensor theory reproducing MOND and the cosmological model
Luc Blanchet, Constantinos Skordis
We propose an alternative scalar-tensor theory based on the Khronon scalar field labeling a family of space-like three-dimensional hypersurfaces. This theory leads to modified Newt…
Stealth black holes in Aether Scalar Tensor theory
Constantinos Skordis, David M. J. Vokrouhlicky
The Aether Scalar Tensor (AeST) theory is an extension of general relativity(GR) successful at reproducing galactic rotational curves, gravitational lensing, linear large scale str…
Aether scalar tensor theory: Hamiltonian Formalism
Marianthi Bataki, Constantinos Skordis, Tom Zlosnik
The Aether Scalar Tensor (AeST) theory is an extension of General Relativity (GR), proposed for addressing galactic and cosmological observations without dark matter. By casting th…
Relativistic Khronon Theory in agreement with Modified Newtonian Dynamics and Large-Scale Cosmology
Luc Blanchet, Constantinos Skordis
We propose an extension of General Relativity (GR) based on a space-time foliation by three-dimensional space-like hypersurfaces labeled by the Khronon scalar field . We show t…
