Dark energy after GW170817, revisited
Edmund J. Copeland, Michael Kopp, Antonio Padilla +2
We revisit the status of scalar-tensor theories with applications to dark energy in the aftermath of the gravitational wave signal GW170817 and its optical counterpart GRB170817A.…
The Parameterized Post-Newtonian-Vainshteinian formalism for the Galileon field
Nadia Bolis, Constantinos Skordis, Daniel B Thomas +1
Recently, an extension to the Parameterized Post-Newtonian (PPN) formalism has been proposed. This formalism, the Parameterized Post-Newtonian-Vainshteinian (PPNV) formalism, is we…
The Dark Matter equation of state through cosmic history
Michael Kopp, Constantinos Skordis, Daniel B. Thomas +1
Cold Dark Matter (CDM) is a crucial constituent of the current concordance cosmological model. Having a vanishing equation of state (EoS), its energy density scales with the invers…
