“…b The power-law model for the primordial spectrum is P(k) = ∆ 2 R k k 0 ns−1 ther varies significantly as the cosmological parameters are varied within their errors in the flat cosmology we consider in this work. The P (k) constraints from the CMB alone overlap well with the power spectrum measurements from the SDSS DR7 LRG sample (Reid et al 2010), which have been deconvolved from their window functions. The ACT data allow us to probe the power spectrum today at scales 0.001 < k < 0.19 Mpc −1 using only the CMB, improving on previous constraints using microwave data.…”

“…The data points between 0.02 < k < 0.19 Mpc −1 show the SDSS DR7 LRG sample, and have been deconvolved from their window functions, with a bias factor of 1.18 applied to the data. This has been rescaled from the Reid et al (2010) 2011). The bottom panel shows the same data plotted on axes where we relate the power spectrum to a mass variance, ∆ M /M, and illustrates how the range in wavenumber k (measured in Mpc −1 ) corresponds to range in mass scale of over 10 orders of magnitude.…”

We present constraints on the primordial power spectrum of adiabatic fluctuations using data from the 2008 Southern Survey of the Atacama Cosmology Telescope (ACT). The angular resolution of ACT provides sensitivity to scales beyond = 1000 for resolution of multiple peaks in the primordial temperature power spectrum, which enables us to probe the primordial power spectrum of adiabatic scalar perturbations with wavenumbers up to k 0.2 Mpc −1 . We find no evidence for deviation from power-law fluctuations over two decades in scale. Matter fluctuations inferred from the primordial temperature power spectrum evolve over cosmic time and can be used to predict the matter power spectrum at late times; we illustrate the overlap of the matter power inferred from CMB measurements (which probe the power spectrum in the linear regime) with existing probes of galaxy clustering, cluster abundances and weak lensing constraints on the primordial power. This highlights the range of scales probed by current measurements of the matter power spectrum.
