Abstract
We propose to study galaxy clusters around Active Galactic
Nuclei (AGN) at a high redshift range of 0.7<z<1.2. In order to
accomplish this we will utilize data from the Spitzer Space Telescope
compiled by Falder et al. (2010). We propose to identify galaxy
clusters by using simple IRAC color selection which has been found to
be effective at unraveling high redshift galaxies (A. Galametz et al.
2011 ). Using a counts-in-cell analysis, we will identify a field as
being overdense if 15 or more IRAC sources are found within 1arcmin (ie.,
0.5 Mpc at 1<z<3) of the targeted galaxy to the 5 sigma flux density
limits of the IRAC data that was targeted. Also, using the color
selection criteria developed by Stern et al. (2005), we will seek out
other AGN surrounding the originally targeted source. The number of
our sample is 168 and we plan on both rediscovering previously known
clusters and protoclusters as well as discovering new galaxy cluster
candidates. The researchers further hope to create some statistical
sampling which would further confirm suggestions that high redshift
radio AGN with high radio luminosity lie in some of the densest
regions in the Universe.
