US Planck Data Analysis Review 1 Kevin Huffenberger, JPLUS Planck Data Analysis Review 910 May 2006 Point Sources Kevin Huffenberger Caltech postdoctoral fellow, JPL 2 US Planck Data Analysis Review 910 May 2006Kevin Huffenberger, JPL 2 Challenge and opportunity Planck Bluebook 3 US Planck Data Analysis Review 910 May 2006Kevin Huffenberger, JPL 3 Contamination by unresolved sources Hinshaw et al WMAP 4 US Planck Data Analysis Review 910 May 2006Kevin Huffenberger, JPL 4 Science with sources Catalog: sensitive with small beams, 30857 GHz, all-sky. Some measure of time-variability. 100s to 1,000s of radio sources : Gigahertz peaked and inverted spectrum sources. AGNs. SZ clusters. 10,000s of dusty star forming galaxies: 1st all-sky catalog of submillimeter sources. Complements narrower, deeper measurements (e.g. ALMA). 5 US Planck Data Analysis Review 910 May 2006Kevin Huffenberger, JPL 5 Tool for optical properties 13 Pointing? Effective beam? Pol. calibration? Scan? Mapmaking? Many delta- function sources. Complications: Deblending Background Noise T ant (K) Symmetric beam simulation30 GHz 6 US Planck Data Analysis Review 910 May 2006Kevin Huffenberger, JPL 6 Best models: Planck source templates Thermal sources modeled by D. Clements (UK) IRAS sources, with extrapolations to Planck bands based on 100 & 60 micron fluxes when available Non-thermal sources by G. De Zotti, J. Gonzalez-Nuevo, M. Massardi, C. Baccigalupi (Italy), L. Toffolatti (Spain), R. Sajac and B. Partridge (US) Brightest microwave sources (e.g., WMAP) included with known positions, SEDs and polarizations SZ clusters (J. Bartlett, France) Other populations modeled from available low frequency source counts 7 US Planck Data Analysis Review 910 May 2006Kevin Huffenberger, JPL 7 Source templates: future directions Refine model of thermal sources. Add WMAP 3-yr. sources and other bright radio sources. Include results of southern 20 GHz survey (Ron Ekers, Australia). Ensure wide use of best simulated sky model. 8 US Planck Data Analysis Review 910 May 2006Kevin Huffenberger, JPL 8 Simplified source modeling Quick and dirty catalogs (KMH): Bright radio sources taken from WMAP. Other sources Poisson distributed with prescribed number counts. Simulated source freq. scaling drawn from distribution. Radio source counts / spectra fit to WMAP. IR source counts fit to SCUBA counts, dusty gray-body spectrum. For tests and algorithm validation. Designer catalogs available by request.
