Abstract

This capstone develops tools usable for the detection of the Integrated Sachs-Wolfe Effect within the data products of the Planck satellite, scheduled to be launched in late April 2009. This project prepared for flight data using simulations of the cosmic microwave background as well as of galaxy surveys. Using these simulated maps as a base, I developed tools to find the power spectrum of the cross correlation in order to detect the ISW effect. With this detection and the corresponding error bars, I effected a comparison with theoretical models. This comparison constrained the value of ΩDE (dark energy density) put into simulations, along with the confidence interval. The products of this investigation will be directly portable to the forthcoming flight data from the Planck satellite.
