Detecting Clusters of Galaxies at High Redshift with the Spitzer Space Telescope

We present an infrared adaptation of the Cluster Red-Sequence method. We modify the two filter technique of Gladders & Yee (2000) to identify clusters based on their R-[3.6] color. We apply the technique to the 4 degree^2 Spitzer First Look Survey and detect 123 clusters spanning the redshift range 0.09 < z < 1.4. Our results demonstrate that the Spitzer Space Telescope will play an important role in the discovery of large samples of high redshift galaxy clusters.

Measuring High Moments of Galaxy Angular Distribution in the First Look Survey using Infrared Array Camera

We present the results of using three methods, the probability distribution function, the Renyi information, and the multi-fractals, to measure the high moments of galaxy angular distribution in the Infrared Array Camera data of the Spitzer First Look Survey. This is the first time that Renyi information is explicitly used to describe the large-scale galaxy spatial distribution, and our galaxy samples are also the first of the kind in their wavelengths and sensitivities.
