BG : IRAS 100 micron

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

Spitzer/FIDEL maps : a fluctuation analysis

ASI Review Padova ICC Contribution 6

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.

SPIRE/HerMES maps : a fluctuation analysis

ASI Review Padova ICC Contribution 7

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.

PEP & HerMES SDP Papers

ASI Review Padova Scientific Activities 8

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 31st

Second-generation papers soon afterwards

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
