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…

Imperfect fluid description of modified gravities
Valerio Faraoni, Jeremy Coté
The Brans-Dicke-like field of scalar-tensor gravity can be described as an imperfect fluid in an approach in which the field equations are regarded as effective Einstein equations.…
