A Multi-Wavelength Catalog of Spitzer Sources in Wide-Area Fields  Spitzer Public Catalogs (SWIRE, Bootes, XFLS) –IRAC-selected –MIPS 24/70/160 always available –MIPS 24 source density generally well-matched with beam size –MIPS 70/160 larger beams increase ambiguity of XID process –Nearest MIPS 24 source is chosen as most likely counterpart  GALEX always available  SDSS available in the North (Astro/Photo Calibration)  Miscellaneous Optical Imaging (NOAO, INT, CFHT)  2MASS always available (Spitzer Astro Calibration)  UKIDSS available in XMM/LH/EN1 fields but little else  Spec-Zs available (but poorly documented) from NED  Extra public Spec-Zs from recent literature HerMES MeetingData Fusion

5. ASI ReviewPadova Scientific Activities5 Spitzer-Warm Observations of HERMES Fields SERVS Observations and Data Fusion  AF & LM & MV are Co-Is of 1400-hr Spitzer Warm SERVS program to obtain IRAC 3.6 and 4.5 micron observations of ~20 deg 2 within SWIRE/HERMES fields  Most fields already observed ten-times deeper than SWIRE  Data Fusion required for Early Science Papers (due in early April)  Ongoing Gemini Optical Imaging Program and miscellaneous follow-up proposals  Working on Photometric Redshift and Stellar Mass estimates SERVS Data Fusion as of 20 Mar 2010

6. Spitzer/FIDEL maps : a fluctuation analysis ASI ReviewPadova ICC Contribution6 P(D) analysis is a technique developed by Scheuer & Ryle 1957 for use in the radio but extended to X-rays & IR in 1970s. P(D) analysis allows to study faint sources where the map spatial resolution is low. We can thus derive information about source number counts down to fluxes corresponding to one source per beam. We applied this tool to study background fluctuations in Spitzer 70 µm FIDEL maps to compare against Franceschini et al. 2010 models.

7. SPIRE/HerMES maps : a fluctuation analysis ASI ReviewPadova ICC Contribution7 Franceschini et al. 2009 We also applied this technique to the new maps from Herschel Space Observatory, in particular to the SPIRE HerMES Maps. The simulated maps are based on Franceschini 2010 model and the P(D) result is consistent whit the P(D) from real maps. This confirms the goodness of the adopted models.

8. PEP & HerMES SDP Papers ASI ReviewPadova Scientific Activities8  Giulia Rodighiero and Mattia Vaccari are respectively leading the PEP “PEP Specific Star Formation Rate vs Stellar Mass up to z~3” and “HerMES SMM Local (0<z<0.2) Luminosity Function” papers.  Coordinated submission to A&A on Mar 31 st  Second-generation papers soon afterwards

9. Where do we go from here?  Over the last 3 years Padova has been consistently  Contributing to SW development and testing effort by PACS and SPIRE ICCs  Working on defining and planning for PACS and HERMES GT KPs  In particular, we’ve been extensively contributing to  PACS/SPIRE DP testing and SPIRE GUI Development  Defining in detail Herschel Extragalactic Surveys “Wedding Cake”  Planning and scheduling HerMES Herschel observations  Obtaining essential ancillary data within HerMES Fields  Consequently we’ve been  Assuming a prominent role within HerMES and PEP KP teams  Assigned the lead of HerMES and PEP SDP papers  Fostering collaborations with colleagues old and new  Placing ourselves in an ideal position to best exploit Herschel data ASI ReviewPadova ICC Contribution9
