dc.descriptionWe demonstrate that combining Cosmic Microwave Background anisotropy measurements from the 1st year WMAP observations with clustering data from the SLOAN galaxy redshift survey yields an indication for primordial anisotropies in the cosmological Neutrino Background.
dc.description4 pages, 4 figures (1 new figure). Discussion expanded following referee suggestions, assumption on the number of massless neutrino families relaxed. Conclusions largely unchanged
