CMBPol Mission Concept Study: Probing Inflation with CMB Polarization
Daniel Baumann, Mark G. Jackson, Peter Adshead +56
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…
Weighing the spatial and temporal fluctuations of the dark universe
Pengjie Zhang, Rachel Bean, Michele Liguori +1
A generic prediction of the standard cosmology, based on general relativity (GR), dark matter and the cosmological constant (and more generally, smooth dark energy), is that, the t…
Impact of Uncertainties in the Cosmological Parameters on the Measurement of Primordial non-Gaussianity
M. Liguori, A. Riotto
We study the impact of cosmological parameters' uncertainties on estimates of the primordial NG parameter f_NL in local and equilateral models of non-Gaussianity. We show that prop…
Limits on Primordial Non-Gaussianity from Minkowski Functionals of the WMAP Temperature Anisotropies
Chiaki Hikage, Takahiko Matsubara, Peter Coles +3
We present an analysis of the Minkowski Functionals (MFs) describing the WMAP three-year temperature maps to place limits on possible levels of primordial non-Gaussianity. In parti…
Galaxy-CMB Cross-Correlation as a Probe of Alternative Models of Gravity
Fabian Schmidt, Michele Liguori, Scott Dodelson
Bekenstein's alternative to general relativity, TeVeS, reduces to Modified Newtonian Dynamics (MOND) in the galactic limit. On cosmological scales, the (potential well <-> overdens…
Matching WMAP 3-yrs results with the Cosmological Slingshot Primordial Spectrum
Cristiano Germani, Michele Liguori
We consider a recently proposed scenario for the generation of primordial cosmological perturbations, the so called Cosmological Slingshot scenario. We firstly obtain a general exp…
