SPITZER

Layered SPITZER Surveys: 

Layered SPITZER Surveys Wide–shallow FLS GTO-shallow SWIRE greatest volume 4 8.5 49 sq deg rare luminous objects large-scale structure Confusion-limited GTO-deep GOODS-IRAC maximum information 2.5 sq deg 300 sq arcmin on faintest resolved sources Ultra-deep GTO-ultra GOODS-24 mm confusion distribution 150 300 sq arcmin

Slide4: 

ELAIS N1: 9 sq. deg SWIRE 3.6 mm survey in ELAIS-N1

Photometric redshifts: 

Photometric redshifts SWIRE-VVDS sample (with VVDS team, PI LeFevre) VIRMOS-VLT Deep Survey spectra andgt;1000 sources ~3% rms in (1+z) andlt;2% outliers phot z method of RR 03, Babbedge et al 04, RR et al 05, some refinements ~ IRAC 3.6 and 4.5 mm big help in reducing outliers z = 1 2 3 4 red: gals, blue QSOs

Photometric redshifts: 

Photometric redshifts All SWIRE Catalogue VVDS: 9 optical bands N1,N2: 5 optical bands Lockman: 3-4 optical bnds CDFS: 3 optical bands z = 1 2 3 4

SWIRE COUNTS AT 24 mm: 

SWIRE COUNTS AT 24 mm 24 mm differential counts (Shupe et al, 2007, Papovich et al 2004) new model for ir counts (developed from RR 2001 models): independent evolution for each component, evolution has to flatten off at z andlt; 0.5 M82 cirrus dust tori

SHADES counts at 850 mm: 

SHADES counts at 850 mm Coppins et al, 2007, astro-ph/0609039

counts at 70-850 mm: 

counts at 70-850 mm new SWIRE 70, 160 and SHADES 850 mm differential counts (Afonso-Luis et al, 2007, in prep, Coppins et al 2007)

The Terahertz background

a z ~ 6.7 galaxy detected by SPITZER : 

a z ~ 6.7 galaxy detected by SPITZER Egami et al, 2005, ApJ 618, L5: z ~ 6.7 lensed galaxy with M = 109 Mo, stellar age at least 50 Myr

AKARI: 

AKARI Japanese mission, 68 cm cooled telescope, first all-sky far infrared survey since IRAS, 90 and 140 mm, sensitivity probably comparable to IRAS FSS, but much better spatial resolution, so in principle may be able to construct deeper all-sky sample than PSCz

HERSCHEL: 

HERSCHEL 3.6 m passively cooled telecope operating at 50-500 mm layered survey will be carried out by SPIRE and PACS teams in guaranteed time, widest area 70 sq deg in 9 areas

PLANCK: 

PLANCK PLANCK will carry out a shallow all-sky extragalactic point-source survey, which will detect many high-z very luminous submm galaxies
