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
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.
Histograms are real P(D) measured inside three
different aperture radius

SPIRE/HerMES maps a fluctuation analysis
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

• Giulia Rodighiero and Mattia Vaccari are
  respectively leading the PEP PEP Specific Star
  Formation Rate vs Stellar Mass up to z3 and
  HerMES SMM Local (0ltzlt0.2) Luminosity Function
  papers.
• Coordinated submission to AA 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, weve 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 weve 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
