Cosmic Infrared Background and New Cosmological Populations [abstract]

Cosmic infrared background (CIB) is produced by emissions from luminous objects spanning the entire history of the Universe including from sources, such as first stars, which are inaccessible to individual telescopic studies. CIB fluctuations, in particular, can be more readily discerned than the actual mean level allowing to overcome the significant Galactic and Solar system foregrounds at NIR wavelengths. I will report on the recent measurements of the CIB fluctuations at near-IR using deep exposure data obtained by the Spitzer Space Telescope. Previous measurements by our group out to scales as large as ~5' had seen the first indication of excess fluctuations above those expected from ordinary galaxies. Recently, these have been extended to sub-degree scales using new data obtained in the course of the 2,000+ hour Spitzer Extended Deep Survey. I will report these new observations, the methods to robustly uncover CIB fluctuations there and the implications of the measurement in isolating new cosmological populations, such as residing during first stars epochs.
