  2. 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 Fields : Observed by Spitzer & to be observed by Herschel GT KPs Padova Scientific Activities

  3. The Cosmic Star Formation History at 0<z<2.5MIR & Bolometric Luminosity Functions from MIPS 24 μm samples Rodighiero et al. (in prep) IR Luminosity Density (i.e. Star Formation Rate) vs redshift Data drawn from most popular “Cosmic Windows” : GOODS + VVDS/SWIRE Padova Scientific Activities

  4. SWIRE to HERMES : Large Areas & Cosmic Variance Large areas are crucial in pinpointing local properties of strongly-evolving populations Vaccari et al. (in prep) 24 μm Local Luminosity Function Red Dots – Rodighiero et al. (in prep) GOODS+VVDS/SWIRE ~ 1 deg2 Black Dots – Marchetti (Tesi di Laurea) SWIRE/SDSS ~ 10 deg2 Black Solid Line – Models by Franceschini et al. (in prep) MIR & FIR Number Counts over 5-10 deg2 areas fully reveal the impact of cosmic variance Padova Scientific Activities

  5. Spectroscopic Observations of FIR Sources at 0<z<0.5 • Large areas and high source densities call for additional optical spectroscopy • Several projects are underway, in collaboration with IAC (Tenerife) and Imperial College (London), mostly targeting 0<z<0.5 objects with the aim of improving constraints on the local luminosity function of SWIRE/HERMES objects Observing runs were: - executed (~500 objects) - approved (~600) - proposed (~1000/1500) Planning for Nov 2008 observing run 600 spectra for SWIRE 70 μm sources and/or X-ray sources in XMMLSS field Padova Scientific Activities

  6. Preparing for PEP & HERMES (SPIRE GT KP) • AF models of extragalactic populations presented in Franceschini et al. (in prep) were invaluable in the planning of and in predicting the results of PEP & HERMES • GR studies of MIR & Bolometric Luminosity Functions will pave the way to similar FIR & sub-mm studies which PEP & HERMES will carry out over 0<z<3 and beyond • MV is responsible for the implementation of multi-wavelength cross-correlation software within the pipeline and for the characterization of the survey selection function, critical aspects in making sense of HERMES statistical observables Background fluctuations due to faint unresolved sources place a fundamental limit to the sensitivity of Herschel observations AF models were thus used to compute the amplitude of these fluctuations, so as to optimize the sensitivities of the various fields making up PEP & HERMES Padova Scientific Activities
