A measurement of secondary cosmic microwave background anisotropies from
  the 2500-square-degree SPT-SZ survey
  We present measurements of secondary cosmic microwave background (CMB)
anisotropies and cosmic infrared background (CIB) fluctuations using data from
the South Pole Telescope (SPT) covering the complete 2540 sq.deg. SPT-SZ survey
area. Data in the three SPT-SZ frequency bands centered at 95, 150, and 220
GHz, are used to produce six angular power spectra (three single-frequency
auto-spectra and three cross-spectra) covering the multipole range 2000 < ell <
11000 (angular scales 5' > \theta > 1'). These are the most precise
measurements of the angular power spectra at ell > 2500 at these frequencies.
The main contributors to the power spectra at these angular scales and
frequencies are the primary CMB, CIB, thermal and kinematic Sunyaev-Zel'dovich
effects (tSZ and kSZ), and radio galaxies. We include a constraint on the tSZ
power from a measurement of the tSZ bispectrum from 800 sq.deg. of the SPT-SZ
survey. We measure the tSZ power at 143 GHz to be DtSZ = 4.08 +0.58 -0.67 \mu
K^2 and the kSZ power to be DkSZ = 2.9 +- 1.3 \mu K^2. The data prefer positive
kSZ power at 98.1% CL. We measure a correlation coefficient of \xi = 0.113
+0.057 -0.054 between sources of tSZ and CIB power, with \xi < 0 disfavored at
a confidence level of 99.0%. The constraint on kSZ power can be interpreted as
an upper limit on the duration of reionization. When the post-reionization
homogeneous kSZ signal is accounted for, we find an upper limit on the duration
\Delta z < 5.4 at 95% CL.
