Turnaround radius in scalar-tensor gravity with quasilocal mass
Valerio Faraoni, Andrea Giusti, Jeremy Côté
Following an existing procedure in general relativity, the turnaround radius of a spherical structure is studied in scalar-tensor gravity using a new prescription for the analog of…
Spacetime mappings of the Brown-York quasilocal energy
Jeremy Côté, Marianne Lapierre-Léonard, Valerio Faraoni
In several areas of theoretical physics it is useful to know how a quasilocal energy transforms under conformal rescalings or generalized Kerr-Schild mappings. We derive the transf…
Quasilocal mass and multipole expansion in scalar-tensor gravity
Valerio Faraoni, Jeremy Coté
A generalization of the Hawking-Hayward quasilocal mass to scalar-tensor gravity is compared, in vacuo and for asymptotically flat stationary geometries, with a recent multipole ex…
Do Solar System experiments constrain scalar-tensor gravity?
Valerio Faraoni, Jeremy Côté, Andrea Giusti
It is now established that, contrary to common belief, (electro-)vacuum Brans-Dicke gravity does not reduce to general relativity for large values of the Brans-Dicke coupling .…
Revisiting the conformal invariance of Maxwell's equations in curved spacetime
Jeremy Côté, Valerio Faraoni, Andrea Giusti
We revisit the invariance of the curved spacetime Maxwell equations under conformal transformations. Contrary to standard literature, we include the discussion of the four-current,…
Two new approaches to the anomalous limit of Brans-Dicke to Einstein gravity
Valerio Faraoni, Jeremy Côté
Contrary to common belief, (electro)vacuum Brans-Dicke gravity does not reduce to general relativity for large Brans-Dicke coupling , a problem which has never been fully solved…
