Abstract: "The blackbody
radiation left over from the Big Bang has been transformed by the expansion of
the Universe into the nearly isotropic 2.73 K cosmic microwave background.
Tiny inhomogeneities in the early Universe left their imprint on the microwave
background in the form of small anisotropies in its temperature. These
anisotropies contain information about basic cosmological parameters,
particularly the total energy density and curvature of the Universe. Here we
report the first images of resolved structure in the microwave background
anisotropies over a significant part of the sky. Maps at four frequencies
clearly distinguish the microwave background from foreground emission. We
compute the angular power spectrum of the microwave background, and find a
peak at Legendre multipole I(peak) = (197 plus/minus 6), with an amplitude
DELTA T(200) = (69 plus/minus 8) (mu)K. This is consistent with that expected
for cold dark matter models in a flat (euclidean) Universe, as favoured by
standard inflationary models."
This 2000 paper in Nature was cited 43
times in current journal articles indexed in the ISI database during
July-August 2001. With its latest citation tally, it currently ranks as the
fourth-most-cited paper in physics published in the last two years, aside from
reviews. The paper, in fact, has ranked among the most cited in physics for
most of 2001. Prior to the most recent bimonthly count, citations to the paper
have accrued as follows:
