We constrain slow-roll inflationary models using the recent Wilkinson Microwave Anisotropy Probe data combined with data from the VSA, CBI, ACBAR and 2dF experiments. We find the slow-roll parameters to be 0<epsilon(1)<0.032 and epsilon(2)+5.0epsilon(1)=0.036+/-0.025. For inflation models Vproportional tophi(alpha) we find that alpha<3.9,4.3 at the 2sigma and 3sigma levels, indicating that the lambdaphi(4) model is under very strong pressure from observations. We define a convergence criterion…

Inflation after WMAP3: confronting the slow-roll and exact power spectra with CMB data
The implications of the WMAP (Wilkinson Microwave Anisotropy Probe) third year data for inflation are investigated using both the slow-roll approximation and an exact numerical integration of the
Single-field inflation constraints from CMB and SDSS data
We present constraints on canonical single-field inflation derived from WMAP five year, ACBAR, QUAD, BICEP data combined with the halo power spectrum from SDSS LRG7. Models with a non-scale-invariant
Constraints on the inflationary expansion from three-year WMAP, small scale CMB anisotropies and large scale structure data sets
We present the constraints on inflationary parameters in a flat ΛCDM universe obtained from the Wilkinson Microwave Anisotropy Probe (WMAP) three-year data release, plus smaller scale cosmic
Inflationary physics from the Wilkinson microwave anisotropy probe
We extract parameters relevant for distinguishing among single-field inflation models from the Wilkinson Microwave Anisotropy Probe (WMAP) data set, and from a combination of the WMAP data and seven
Primordial fluctuations and cosmological inflation after WMAP 1.0
The observational constraints on the primordial power spectrum have tightened considerably with the release of the first-year analysis of the WMAP observations, especially when combined with the
Slow roll reconstruction: constraints on inflation from the 3 year WMAP data set
We study the constraints on the inflationary parameter space derived from the 3 year WMAP data set using 'slow roll reconstruction', using the SDSS galaxy power spectrum to gain further leverage
Constraints on braneworld inflation from CMB anisotropies
We obtain observational constraints on Randall–Sundrum type II braneworld inflation using a compilation of data including WMAP, the 2dF and latest SDSS galaxy redshift surveys. We place constraints
Constraints on the primordial power spectrum from high-resolution Lyman α forest spectra and WMAP
ABSTRACT The combined analysis of the cosmic microwave background on large scalesand Lyman-α forest on small scales provides a sufficiently long lever arm toobtain strong constraints on the slope and
Primordial Black Holes, Eternal Inflation, and the Inflationary Parameter Space after WMAP5
We consider constraints on inflation driven by a single, minimally coupled scalar field in the light of the WMAP5 dataset, as well as ACBAR and the SuperNova Legacy Survey. We use the Slow Roll
