Morphological and Spectral Features of the WMAP Haze (15'+5')
 
The WMAP "haze" is an extended region of excess microwaves towards the 
Galactic Center relative to known ISM 
emissions.  I will first present the results of our analysis of the morphological 
and spectral features of the haze. 
From there, I will show that they are consistent with synchrotron emission from 
an injection of high energy 
electrons/positrons sourced by ~500 GeV neutralino DM annihilations with 
thermal relic cross section in the galactic 
DM halo with a rho~r^-1.2 density profile and no boost factor.  Further, I will 
show that they are inconsistent with 
a point source injection from massive explosions such as GRBs, SNe, etc.  Halo 
annihilations of this type have 
significant consequences for present and future indirect observations such as 
Planck, PAMELA, and GLAST.
