Investigating dark energy experiments with principal components
Robert G. Crittenden, Levon Pogosian, Gong-Bo Zhao
We use a principal component approach to contrast different kinds of probes of dark energy, and to emphasize how an array of probes can work together to constrain an arbitrary equa…
Tracking Dark Energy with the ISW effect: short and long-term predictions
Levon Pogosian, Pier Stefano Corasaniti, Christian Stephan-Otto +2
We present an analysis of the constraining power of future measurements of the Integrated Sachs-Wolfe (ISW) effect on models of the equation of state of dark energy as a function o…
Bounds on Cosmic Strings from WMAP and SDSS
Mark Wyman, Levon Pogosian, Ira Wasserman
We find the constraints from WMAP and SDSS data on the fraction of cosmological fluctuations sourced by local cosmic strings using a Markov Chain Monte Carlo (MCMC) analysis. In ad…
