Constraining neutrino masses with the ISW-galaxy correlation function
Julien Lesgourgues, Wessel Valkenburg, Enrique Gaztanaga
Temperature anisotropies in the Cosmic Microwave Background (CMB) are affected by the late Integrated Sachs-Wolfe (lISW) effect caused by any time-variation of the gravitational po…
New constraints on the observable inflaton potential from WMAP and SDSS
Julien Lesgourgues, Wessel Valkenburg
We derive some new constraints on single-field inflation from the Wilkinson Microwave Anisotropy Probe 3-year data combined with the Sloan Luminous Red Galaxy survey. Our work diff…
The cosmology of the nonsymmetric theory of gravitation
Tomislav Prokopec, Wessel Valkenburg
We show that during cosmological inflation the nonsymmetric metric tensor theory of gravitation develops a spectrum which is potentially observable by cosmic microwave background o…
