Cosmic infrared background
Invited talk
The extragalactic background light (EBL) is the relic emission of all processes of structure formation in the Universe. About half of this background, called the Cosmic Infrared Background (CIB) is emitted in the 8–1000 microns range, and peaks around 150 microns. It is due to the dust reemission from star formation processes and AGN emission. The CIB SED constraints the model of star...

In our recent paper (Keenan et al. 2010, accepted to ApJ), we present a current best estimate of the integrated near-infrared (NIR) extragalactic background light (EBL) attributable to resolved galaxies in J, H, and Ks. We derive these new limits by combining our deep wide-field NIR photometry from five widely separated fields with other studies from the literature to create a galaxy counts...

Launched in May 2009, Herschel is providing stunning results: the first PACS extragalactic surveys are giving an unprecedented view of the Infra-Red sky, unveiling the far-IR emission of many galaxies, up to redshifts z~2 and beyond.
The PACS Evolutionary Probe extragalactic survey (PEP, P.I. Lutz) samples four different layers in the cosmological ``wedding cake'', from shallow wide fields...

The fluctuation analysis of the near-infrared background was performed based on the NEP survey at 2.4, 3.2 and 4.1 μm carried out by Japanese infrared astronomy satellite, AKARI. The excess fluctuation powers were detected at the angles larger than 100 arcsec, and they show turnover at tens of arcmin. The excess fluctuating power has a blue stellar spectrum, and correlation between wavelength...
