Raphael Flauger publishes paper that questions BICEP2’s gravitational wave discovery

Two months ago, a team of cosmologists reported that it had spotted the first direct evidence that the newborn universe underwent an exponential growth spurt known as inflation (Science, 21 March, p. 1296).   Raphael Flauger, who will join the McWilliams Center and CMU Physics faculty this fall, has published a paper that questions the BICEP2’s gravitational wave discovery.  His analysis suggests the signal, a subtle pattern in the afterglow of the big bang, or cosmic microwave background (CMB), could be an artifact produced by dust within our own galaxy.
