Forecasting Cosmic Parameter Errors from Microwave Background Anisotropy
Experiments
Authors:
J. Richard Bond,
George Efstathiou & Max Tegmark
Abstract:
Accurate measurements of the cosmic microwave background (CMB) anisotropies
with an angular resolution of a few arcminutes can be used to determine
fundamental cosmological parameters such as the Hubble constant H_0, the
density parameter Omega_0 and the baryon density parameter Omega_b, to
a precision of about a percent or better. Assuming the true theory is a
variant of inflationary cold dark matter cosmologies, we calculate the
accuracy with which cosmological parameters can be determined by the next
generation of CMB satellites, MAP and Planck. We pay special attention
to:
-
the accuracy of the computed derivatives of the CMB power spectrum C_l;
-
the number and choices of parameters;
-
the inclusion of prior knowledge of the values of various parameters.
