Abstract
The WMAP haze is an excess in the 22 to 93 GHz frequency bands of WMAP extending about 10 degrees from the galactic center. We show thatsynchrotron emission from electron-positron pairs injected into theinterstellar medium by the galactic population of pulsars withenergies in the 1 to 100 GeV range can explain the frequency spectrumof the WMAP haze and the drop in the average haze power withlatitude. The same spectrum of high energy electron-positron pairsfrom pulsars, which gives rise to the haze, may also generate theobserved excesses in AMS, HEAT and PAMELA. We discuss the spatialmorphology of the pulsar synchrotron signal and its deviation fromspherical symmetry, which may provide an avenue to determine the pulsarcontribution to the haze.
