What do WMAP and SDSS really tell about inflation?
Julien Lesgourgues, Alexei A. Starobinsky, Wessel Valkenburg
We derive new constraints on the Hubble function H(phi) and subsequently on the inflationary potential V(phi) from WMAP 3-year data combined with the Sloan Luminous Red Galaxy surv…
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…
How much of the inflaton potential do we see?
Wessel Valkenburg
We discuss the latest constraints on a Taylor-expanded scalar inflaton potential, obtained focusing on its observable part only. This is in contrast with other works in which an ex…
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…
