Junction conditions at spacetime singularities
Eran Rosenthal
A classical model for the extension of singular spacetime geometries across their singularities is presented. The regularization introduced by this model is based on the following…
Modification to the Luminosity Distance Redshift Relation in Modified Gravity Theories
Éanna É. Flanagan, Eran Rosenthal, Ira M. Wasserman
We derive an expression for the luminosity distance as a function of redshift for a flat Robertson-Walker spacetime perturbed by arbitrary scalar perturbations possibly produced by…
Cosmological backreaction and spatially averaged spatial curvature
Eran Rosenthal, Éanna É. Flanagan
It has been suggested that the accelerated expansion of the Universe is due to backreaction of small scale density perturbations on the large scale spacetime geometry. While eviden…
Extended Palatini action for general relativity and the natural emergence of the cosmological constant
Eran Rosenthal
In the Palatini action of general relativity the connection and the metric are treated as independent dynamical variables. Instead of assuming a relation between these quantities,…
Can Gravity Probe B usefully constrain torsion gravity theories?
Eanna E. Flanagan, Eran Rosenthal
In most theories of gravity involving torsion, the source for torsion is the intrinsic spin of matter. Since the spins of fermions are normally randomly oriented in macroscopic bod…
Second-order gravitational self-force
Eran Rosenthal
We derive an expression for the second-order gravitational self-force that acts on a self-gravitating compact-object moving in a curved background spacetime. First we develop a new…
