CMBPol Mission Concept Study: Probing Inflation with CMB Polarization
Daniel Baumann, Mark G. Jackson, Peter Adshead +56
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…
The inflationary gravitational-wave background and measurements of the scalar spectral index
Tristan L. Smith, Marc Kamionkowski, Asantha Cooray
Inflation predicts a stochastic background of gravitational waves over a broad range of frequencies, from those accessible with cosmic microwave background (CMB) measurements, to t…
Axion constraints in non-standard thermal histories
Daniel Grin, Tristan L. Smith, Marc Kamionkowski
It is usually assumed that dark matter is produced during the radiation dominated era. There is, however, no direct evidence for radiation domination prior to big-bang nucleosynthe…
The effects of Chern-Simons gravity on bodies orbiting the Earth
Tristan L. Smith, Adrienne L. Erickcek, Robert R. Caldwell +1
One of the possible low-energy consequences of string theory is the addition of a Chern-Simons term to the standard Einstein-Hilbert action of general relativity. It can be argued…
Solar System constraints to general f(R) gravity
Takeshi Chiba, Tristan L. Smith, Adrienne L. Erickcek
It has been proposed that cosmic acceleration or inflation can be driven by replacing the Einstein-Hilbert action of general relativity with a function f(R) of the Ricci scalar R.…
Solar System tests DO rule out 1/R gravity
Adrienne L. Erickcek, Tristan L. Smith, Marc Kamionkowski
Shortly after the addition of a 1/R term to the Einstein-Hilbert action was proposed as a solution to the cosmic-acceleration puzzle, Chiba showed that such a theory violates Solar…
