Abstract
- We have independently measured the genus topology of the temperature fluctuations in the cosmic microwave background seen by the Wilkinson Microwave Anisotropy Probe (WMAP). A genus analysis of the WMAP data indicates consistency with Gaussian random-phase initial conditions, as predicted by standard inflation.<br />Comment: PDF: http://www.astro.virginia.edu/~wnc5c/WMAPtopology.pdf
