Mimicking general relativity in the solar system
Luca Amendola, Christos Charmousis, Stephen C. Davis
In order for a modified gravity model to be a candidate for cosmological dark energy it has to pass stringent local gravity experiments. We find that a Brans-Dicke (BD) theory with…
Ernst equation and spheroidal coordinates with a cosmological constant term
Christos Charmousis
We discuss solution generating techniques treating stationary and axially symmetric metrics in the presence of a cosmological constant. Using the recently found extended form of Er…
Thick self-gravitating plane-symmetric domain walls
Filipe Bonjour, Christos Charmousis, Ruth Gregory
We investigate a self-gravitating thick domain wall for a potential. The system of scalar and Einstein equations admits two types of non-trivial solutions: domain wall solut…
Can a self-gravitating thin cosmic string obey the Nambu-Goto dynamics ?
B. Boisseau, C. Charmousis, B. Linet
We assume that a self-gravitating string is locally described by a thin tube of matter represented by a ``smoothed conical metric''. If we impose a specific constraint on the model…
