Realisations of type III stress-energy tensors of the Hawking-Ellis classification in scalar-tensor gravity
Narayan Banerjee, Valerio Faraoni, Robert Vanderwee +1
The ``ugly duckling'' of the Segré-Plebański-Hawking-Ellis classification of stress-energy tensors is believed to be either impossible or extremely difficult to realise in Einstein…

Tolman-Ehrenfest's criterion of thermal equilibrium extended to conformally static spacetimes
Valerio Faraoni, Robert Vanderwee
With insight from examples and physical arguments, the Tolman-Ehrenfest criterion of thermal equilibrium for test fluids in static spacetimes is extended to local thermal equilibri…
