Combined analysis of the integrated Sachs-Wolfe effect and cosmological implications
Tommaso Giannantonio, Ryan Scranton, Robert G. Crittenden +4
We present a global measurement of the integrated Sachs-Wolfe (ISW) effect obtained by cross-correlating all relevant large scale galaxy data sets with the cosmic microwave backgro…
The effect of reionization on the CMB-density correlation
Tommaso Giannantonio, Robert Crittenden
In this paper we show how the rescattering of CMB photons after cosmic reionization can give a significant linear contribution to the temperature-matter cross-correlation measureme…
Measuring deviations from a cosmological constant: a field-space parameterization
Robert Crittenden, Elisabetta Majerotto, Federico Piazza
Most parameterizations of the dark energy equation of state do not reflect realistic underlying physical models. Here, we develop a relatively simple description of dark energy bas…
Computing challenges of the Cosmic Microwave Background
J. Richard Bond, Robert G. Crittenden, Andrew H. Jaffe +1
The Cosmic Microwave Background (CMB) encodes information on the origin and evolution of the universe, buried in a fractional anisotropy of one part in 100,000 on angular scales fr…
Igloo Pixelizations
Robert G. Crittenden
Upcoming microwave background experiments will see an incredible increase in the volume of data to be analyzed, which makes the choice of how it is discretized on the sky a crucial…
Polarization-Temperature Correlations in the Microwave Background
Robert Crittenden
The polarization of the CMB offers a potentially valuable probe of the physics of the early universe, specifically of the velocity of the photon-baryon fluid on the last scattering…
