Long-Wavelength Cosmological Surveysin the Era of the Great Observatories Padova has been involved into long-wavelength studies of extragalactic populations since the 1980s and has consistently contributed to large-area survey projects carried out with IRAS, ISO, Spitzer and now Herschel SWIRE ~ 50 ☐2 SWIRE Fieldsobserved by Spitzer & to be observed by Herschel GT KPs (PER & HERMES)interplay of deep and shallow observations in “nested” surveys Padova Scientific Activities
The Cosmic Star Formation History at 0 < z < 2.5Deep 24 micron samples broken down into Luminosity Bins The deepest Spitzer/MIPS observations at 24 micron in the GOODS and other fields have been combined to produce MIR & Luminosity Functions at 0 < z < 2.5 allowing an estimate of the contributions to the Bolometric Luminosity Functions by sources of different luminosities The space density of 24 micron selected galaxies as a function of redshift in different luminosity classes. The colored labels by each curve indicate the corresponding IR luminosity in logarithmic solar units. Rodighiero+ (in prep) GOODS & VVDS/SWIRE Fields Padova Scientific Activities
The SWIRE-SDSS Database and the FIR LLFsExtragalactic FIR Astronomy over ~10 deg2 SWIRE/HERMES Areas 24 micron Redshift Distribution 70 micron LLF Vaccari+ 09 arXiv:0902.0248 SDSS provides an optical spectro-photometric dataset well matched to SWIRE/MIPS depths, allowing to probe the properties of flux-limited samples of local (z<~0.5) FIR galaxies in a complete and reliable manner. The use of Virtual Observatory tools which have recently been made available to the community greatly simplified the assembly and cross-correlation of the otherwise sparsely available multi-wavelength datasets. The resulting SWIRE-SDSS database not only allows to reliably estimate the Local Luminosity Functions at 24/70/160 micron but also provides an invaluable resource for science exploitation of HERMES data.

Ancillary Observations of HERMES FieldsSpitzer Warm and Spectroscopic Observing Proposals • AF & MV were Co-Is of the 1400-hr Spitzer Warm approved proposal for IRAC 3.6 and 4.5 micron observations of ~20 deg2 within SWIRE/HERMES fields • 3 extra nights (adding to 6) were approved to expand spectroscopic coverage of MIPS 70 & 160 micron sources within LH/EN1/EN2 SWIRE/HERMES fields May 09 Run Spitzer Warm observations will allow much improved stellar mass estimates up to z~6 over SWIRE/HERMES-like areas, providing an ideal counterpart to the VISTA JHK & Herschel FIR/SMM Surveys Nov 08 Run Incremental Observing Runs 2007/08/09/… Padova Scientific Activities
Preparing for PEP (PACS GT) & HERMES (SPIRE GT) KPs • We have been extensively and variously involved in finalizing the details of the observations for the PEP and HERMES KP GTs, with a special emphasis on those planned for SD • In particular we’ve contributed to • Modeling Extragalactic Populations (AF & MV) • Simulating Catalogs & Images (GR & MV) • Studying HERMES Field Visibility during SD Phase and Finalizing AORs accordingly (MV) • Developing & Testing Frequentist & Bayesian Multi-Wavelength XID S/W (MV) • Assembling VO-compliant Multi-Wavelength Ancillary Databases (GM & LM & GR & MV) • “Discussion” about SD Phase Papers Simulated Extragalactic Skies at PACS wavelengths enabling extensive PACS pipeline testing Padova Scientific Activities
