      The dark energy cosmic clock: A new way to parametrise the equation of state 

      Tarrant, E. R. M.; Copeland, E. J.; Padilla, A.; Skordis, C. (2013)
      We propose a new parametrisation of the dark energy equation of state, which uses the dark energy density, Ωe as a cosmic clock. We expand the equation of state in a series of orthogonal polynomials, with Ωe as the expansion ...
