PROBING THE WARM DARK MATTER WITH THE HIGH-zQUASAR LUMINOSITY FUNCTION

Hyunmi Song, Jounghun Lee
2009 Astrophysical Journal  
In a warm dark matter (WDM) cosmology, the first objects to form at z>=20 are one dimensional filaments with mean length on the order of the WDM free-streaming scale.  ...  Then, we determine the rate of its decrease in the mass section corresponding to the free streaming scale of a WDM particle of mass m_v.  ...  But, for our case the cloud-in-clouds will not occur since there are no substructures embedded in the early-universe filaments within which the particles just free-stream.  ...
