Dear HPS, The Planck collaboration has just released a large amount of new information. See: http://www.sciops.esa.int/index.php?project=PLANCK&page=Planck_Published_Papers And for the main summary paper: http://arxiv.org/abs/1303.5062 I would be very interested in learning more about how these new results impact the search for heavy photons. Cheers, Maurik
