Spitzer_Approved_Extragalactic Mar 25, 10 16:24 Page 579/742 Spitzer Space Telescope − General Observer Proposal #20439 Ultra−Deep IRAC Imaging of Massive Lensing Galaxy Clusters: Probing the Reionization Era with Spitzer Principal Investigator: Eiichi Egami Institution: Steward Observatory, University of Arizona Technical Contact: Eiichi Egami, U. Arizona Co−Investigators: Jean−Paul Kneib, Observatoire de Marseille Graham Smith, California Institute of Technology Richard Ellis, California Institute of Technology Michael Santos, University of Cambridge Daniel Stark, California Institute of Technology Jiasheng Huang, Center for Astrophysics Science Category: galaxy clusters and groups Observing Modes: IracMap Hours Approved: 44.5 Abstract: Locating and characterizing the first subgalactic sources that may have been responsible for completing cosmic reionization and ending the ‘‘Dark Ages’’ represents the latest frontier in observational cosmology. The remarkable potential of Spitzer to probe the reionzation era was demonstrated dramatically by the IRAC detection of a gravitationally−lensed z~7 galaxy at 3.6 and 4.5 um made by our group. The results have provided a number of significant constraints on the physical properties of this galaxy. Here, we propose to conduct ultra−deep IRAC imaging (10 hrs per band) of two of the most well−studied lensing clusters, Abell 1689 and Abell 2218, in our sample. Our goal is to detect more examples of lensed galaxies at z=6−8 and to explore for systems at higher redshift.

Florida Ranga−Ram Chary, SSC Leonidas Moustakas, JPL/Caltech Edward Wright, UCLA Daniel Stern, JPL/Caltech Roberto DePropris, CTIO Science Category: galaxy clusters and groups Observing Modes: IracMap MipsPhot Hours Approved: 19.8 Abstract: The incidence of LIRGs and ULIRGs is roughly two orders of magnitude higher in the field at redshift z > 1, and at these redshifts such objects dominate the global star formation activity. Mergers which fuel such activity might be expected to enhance the frequency of LIRGs in dense environments. We propose to use MIPS to obtain a census of LIRGs in z > 1 galaxy clusters from a well defined sample found in the IRAC Shallow Survey. Supporting IRAC and HST ACS data are also requested.

Spitzer_Approved_Extragalactic Mar 25, 10 16:24 Page 581/742 Spitzer Space Telescope − Guaranteed Time Observer Proposal #30 IRAC Shallow Survey Principal Investigator: Peter Eisenhardt Institution: JPL Technical Contact: Peter Eisenhardt, JPL Science Category: galaxy clusters and groups Observing Modes: IracMap Hours Approved: 61.8 Abstract: The NOAO deep survey is presently surveying a 9 − 10 square degree region in Bootes to K=19.5 and R=26. Data in Bw, I, J and H is also being obtained. The MIPS and IRS GTO teams are planning to survey this region with MIPS. The primary objectives for the IRAC survey of this region are to identify galaxy clusters with redshifts greater than one, and to find field brown dwarfs. If the luminosity evolution observed in clusters to redshift one continues to hold, we expect to detect L*+1 (evolving) cluster galaxies to z=2. Spitzer_Approved_Extragalactic Printed_by_SSC Mar 25, 10 16:24 Page 582/742 Spitzer Space Telescope − General Observer Proposal #30940 Tracing Star Formation History in RCS Galaxy Clusters Principal Investigator: Erica Ellingson Institution: University of Colorado Technical Contact: Erica Ellingson, University of Colorado Co−Investigators: Jessica Jones, U. Colorado Howard Yee, University of Toronto Tracy Webb, McGill University Mike Gladders, U. Chicago Yeong Loh, U. Colorado Amy Bender, U. Colorado Science Category: Galaxy Clusters and Groups Observing Modes: MipsPhot Hours Approved: 63.7 Abstract: We propose to obtain MIPS 24micron images for 48 clusters selected from the Red−Sequence Cluster Survey to study the evolution of star formation history and AGN fraction and their dependence on galaxy environment. The cluster sample contains relatively rich clusters (50% with estimated richness richer than mid−Abell class 1), and covers a large redshift range (0.3 to 1.1) uniformly. Current studies of star formation in mid−redshift suggest that a significant fraction of star formation in clusters may be hidden by dust. A statistically robust census using a well−defined cluster sample will greatly improve our understanding of galaxy evolution clusters and the role the environment plays. We will be able to measure star formation rate to 30 Msun/yr, for the overall sample, and to ~10−15Msun/yr for a subsample of z~1 clusters. The combination of the MIPS data and allocated IRAC imaging of the same sample will allow us to disentangle starburst/AGN sources. We will derive the excess 24micron sources in clusters as a function of redshift, study the spatial distribution of dusty starbursts and AGN in clusters, and the dependence of these activities on the properties of the clusters. Furthermore, these clusters have extensive ancillary follow−up data, including deep 4−color optical photometry, H or K band NIR imaging, multi−object spectroscopy, HST−ACS images, and SCUBA and deep radio imaging, allowing us to carry out detailed studies of the properties of 24micron luminous galaxies in clusters.
