Long-Wavelength Cosmological Surveys
in 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

GOODS and other fields have been
combined to produce MIR &

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 Fields
Spitzer Warm and Spectroscopic Observing Proposals
 AF & MV were Co-Is of the 1400-hr Spitzer Warm approved proposal for IRAC

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
