Prospects For Detecting Dark Matter With GLAST In Light Of The WMAP Haze

Understand

Observations by the WMAP experiment have identified an excess of microwave emission from the center of the Milky Way.

• It has previously been shown that this "WMAP Haze" could be synchrotron emission from relativistic electrons and positrons produced in the annihilations of dark matter particles.
• In particular, the intensity, spectrum and angular distribution of the WMAP Haze is consistent with an electroweak scale dark matter particle (such as a supersymmetric neutralino or Kaluza-Klein dark matter in models with universal extra dimensions) annihilating with a cross section on the order of sigma v~3x10^-26 cm^3/s and distributed with a cusped halo profile.
• No further exotic astrophysical or annihilation boost factors are required.
