first stars/first galaxies

We studied the constribution of high-z dwarf galaxies and first stars to the cosmic near-infrard background (CNIRB) by using numerical simulations, found that the these sources cannot account for the measured CNIRB flucutaitons level.

We proposed that direct colloapse black holes (DCBHs) may be the major sources of the observed CNIRB, and investigated the their formation.
