Measuring the Three Point Correlation Function of the Cosmic Microwave Background
Gang Chen, Istvan Szapudi
We present a new method to estimate three-point correlations in Cosmic Microwave Background maps. Our Fast Fourier Transform based implementation estimates three-point functions us…
The Fourth Data Release of the Sloan Digital Sky Survey
J. K. Adelman-McCarthy et al.
This paper describes the fourth data release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through June 2004. The data release includes five-band…
The Monopole Moment of the Three-Point Correlation Function of the 2-degree Field Galaxy Redshift Survey
Jun Pan, Istvan Szapudi
We measure the monopole moment of the three-point correlation function on scales $1\mpc-70\mpc$ in the Two degree Field Galaxy Redshift Survey (2dFGRS). Volume limited samples are…
Introduction to Higher Order Spatial Statistics in Cosmology
István Szapudi
In this lecture notes I concentrate on the classic and widely applicable characterization of higher order statistics by joint moments, a.k.a. higher order correlation functions, an…
Fast Edge Corrected Measurement of the Two-Point Correlation Function and the Power Spectrum
István Szapudi, Jun Pan, Simon Prunet +1
We present two related techniques to measure the two-point correlation function and the power spectrum with edge correction in any spatial dimensions. The underlying algorithm uses…
Cosmological Three-Point Function: Testing The Halo Model Against Simulations
Pablo Fosalba, Jun Pan, Istvan Szapudi +1
We perform detailed comparison of the semi-analytic halo model predictions with measurements in numerical simulations of the two and three point correlation functions (3PCF), as we…
