From the abstract: "A simple cosmological model with only six parameters
(matter density, Omega(m)h(2), baryon density, Omega(b)h(2), Hubble
constant, H-0, amplitude of fluctuations, sigma(8), optical depth, tau, and
a slope for the scalar perturbation spectrum, n(s)) fits not only the 3
year WMAP temperature and polarization data, but also small-scale CMB data,
light element abundances, large-scale structure observations, and the
supernova luminosity/distance relationship. Using WMAP data only, the
best-fit values for cosmological parameters for the power-law flat Lambda
cold dark matter (Lambda CDM) model are (Omega(m)h(2), Omega(b)h(2), h,
n(s), tau, sigma(s)) = (0.1277(-0.0079)(+0.0080), 0.02229 +/- 0.00073,
0.732(-0.032)(+0.031), 0.958 +/- 0.016,0.089 +/- 0.030,
0.761(-0.048)(+0.049)). The 3 year data dramatically shrink the allowed
volume in this six-dimensional parameter space. Assuming that the
primordial fluctuations are adiabatic with a power-law spectrum, the WMAP
data alone require dark matter and favor a spectral index that is
significantly less than the Harrison-Zel'dovich-Peebles scale-invariant
spectrum ( n(s) = 1, r = 0)....Even if we do not include the prior that the
universe is flat, by combining WMAP, large-scale structure, and supernova
data, we can still put a strong constraint on the dark energy equation of
state, w = -1.08 +/- 0.12. For a flat universe, the combination of WMAP and
other astronomical data yield a constraint on the sum of the neutrino
masses, Sigma m(nu) < 0.66 eV (95%CL). Consistent with the predictions
of simple inflationary theories, we detect no significant deviations from
Gaussianity in the CMB maps using Minkowski functionals, the bispectrum,
trispectrum, and a new statistic designed to detect large-scale
anisotropies in the fluctuations."
This 2007 report from Astrophysical Journal Supplement Series was
cited 121 times in current journal articles indexed by Clarivate
during May-June 2009. After ten consecutive bimonthly periods as the
most-cited non-review physics paper published in the last two years, the
paper now slips a rung to the #2 spot (surrendering the top perch to its
successor, a 2009 report on the WMAP mission). With this latest two-month
interval, the paper now reaches the two-year "retirement" age for Hot
Papers. But it was quite a run. Prior to the most recent tally, citations
