The Rise of Dark Energy

  title={The Rise of Dark Energy},
  author={E. Linder},
A frontier for the next generation of cosmic surveys after the ones now getting underway will be pushing to higher redshift, earlier in the evolution of the universe. Cosmicly, this is not simply a dull era of complete matter domination: the dark energy density at redshift z = 2 is expected to be about double the current baryon density and one quarter the current matter density. How dark energy rises to dominate the current expansion may also offer clues to its nature. For example, at z = 2.5… Expand

Searching for dark energy in the matter-dominated era
Most efforts to detect signatures of dynamical dark energy are focused on late times, $z \lesssim 2$, where the dark energy component begins to dominate the cosmic energy density. Many theoreticalExpand
