Estimating N -point Correlation Functions from Pixelized Sky Maps
We develop, implement and test a set of algorithms for estimating N -point correlation functions from pixelized sky maps. These algorithms are slow, in the sense that they do not break the O(N pix) barrier, and yet, they are fast enough for efficient analysis of data sets up to several hundred thousand pixels. The typical application of these methods is Monte Carlo analysis using several thousa...
متن کاملThe N -point Correlation Functions of the First-year Wilkinson Microwave Anisotropy Probe Sky Maps
We compute the two-, threeand four-point correlation functions from the Wilkinson Microwave Anisotropy Probe (WMAP) data, and compare these to a Monte Carlo ensemble of 5000 realizations, based on the best-fit WMAP running-index spectrum of Gaussian fluctuations. The analysis is carried out in three steps, covering small (< 72), intermediate (< 5) and large scales (up to 180). On the largest sc...
متن کاملFast n-point correlation functions and three-point lensing application
We present a new algorithm to rapidly compute the two-point (2PCF), three-point (3PCF) and n-point (n-PCF) correlation functions in roughly O(N) time for N particles, instead of O(Nn) as required by brute force approaches. This technique exploits node-to-node correlations of a recursive bisectional binary tree. A balanced tree construction minimizes the depth of the tree and the worst case erro...
متن کاملPoint sources in the MAP sky maps
We discuss point sources foregrounds for the MAP experiment. We consider several possible strategies for removing them and we assess how the statistics of the CMB signal are affected by the residual sources. Assuming a power law distribution for the point sources, we propose a method aimed to determine the slope of the distribution from the analysis of the moments of the observed maps. The same...
متن کاملThe N-point correlation functions of the COBE-DMR maps revisited
We calculate the two-, threeand (for the first time) four-point correlation functions of the COBE -DMR 4-year sky maps, and search for evidence of non-Gaussianity by comparing the data to Monte Carlo-simulations of the functions. The analysis is performed for the 53 and 90 GHz channels, and five linear combinations thereof. For each map, we simulate an ensemble of 10 000 Gaussian realisations b...
