Characterizing Inflationary Perturbations: The Uniform Approximation
Salman Habib, Andreas Heinen, Katrin Heitmann +2
The spectrum of primordial fluctuations from inflation can be obtained using a mathematically controlled, and systematically extendable, uniform approximation. Closed-form expressi…

Future Cosmic Microwave Background Constraints to the Baryon Density
Marc Kamionkowski, Gerard Jungman, Arthur Kosowsky +1
We discuss what can be learned about the baryon density from an all-sky map of the cosmic microwave background (CMB) with sub-degree angular resolution. With only minimal assumptio…
