Early reionization by cosmic strings revisited
Levon Pogosian, Alexander Vilenkin
Measurements of the CMB temperature anisotropy and the temperature-polarization cross correlation by WMAP suggest a reionization redshift of . On the other hand, o…

Anthropic predictions for vacuum energy and neutrino masses
Levon Pogosian, Alexander Vilenkin, Max Tegmark
It is argued that the observed vacuum energy density and the small values of the neutrino masses could be due to anthropic selection effects. Until now, these two quantities have b…

Observational constraints on cosmic strings: Bayesian analysis in a three dimensional parameter space
Levon Pogosian, Mark Wyman, Ira Wasserman
Current data exclude cosmic strings as the primary source of primordial density fluctuations. However, in a wide class of inflationary models, strings can form at later stages of i…
