Measuring dark energy with the integrated Sachs-Wolfe effect
Tommaso Giannantonio
I present to this conference our latest measurements of the integrated Sachs-Wolfe (ISW) effect. After a brief review of the reasons for which this effect arises and of the techniq…
Detectability of a phantom-like braneworld model with the integrated Sachs-Wolfe effect
Tommaso Giannantonio, Yong-Seon Song, Kazuya Koyama
We study a braneworld model in which a phantom-like behaviour occurs with only cold dark matter and a cosmological constant, due to a large distance modification of gravity. With t…
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…
Constraining dark energy with cross-correlated CMB and Large Scale Structure data
P. S. Corasaniti, T. Giannantonio, A. Melchiorri
We investigate the possibility of constraining dark energy with the Integrated Sachs Wolfe effect recently detected by cross-correlating the WMAP maps with several Large Scale Stru…
