Manifestly covariant variational principle for gauge theories of gravity
Michael Hobson, Anthony Lasenby, Will Barker
A variational principle for gauge theories of gravity is presented, which maintains manifest covariance under the symmetries to which the action is invariant, throughout the calcul…

Einstein-Proca theory from the Einstein-Cartan formulation
Will Barker, Sebastian Zell
We construct a theory of gravity in which a propagating massive vector field arises from a quadratic curvature invariant. The Einstein-Cartan formulation and a partial suppression…

Does gravitational confinement sustain flat galactic rotation curves without dark matter?
W. E. V. Barker, M. P. Hobson, A. N. Lasenby
The short answer is . Specifically, this paper considers a recent body of work which suggests that general relativity requires neither the support of dark mat…
