Inflationary physics from the Wilkinson microwave anisotropy probe
- Physics
- 2004
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
- Physics
- 2004
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…
Boundary inflation and the WMAP data
- Physics
- 2006
Inflation in a five-dimensional brane world model with two boundary branes is studied. We make use of the moduli space approximation whereby the low energy theory reduces to a four-dimensional…
Constraints on braneworld inflation from CMB anisotropies
- Physics
- 2003
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…
Inflation after WMAP3
- Physics
- 2007
I discuss the current status of inflationary cosmology in light of the recent WMAP 3-year data release. The basic predictions of inflation are all supported by the data. Inflation also makes…
Monte Carlo Markov chains analysis of WMAP3 and SDSS data points to broken symmetry inflaton potentials and provides a lower bound on the tensor to scalar ratio

background (CMB) and large scale structure (LSS) data (including the three years WMAP data) with single field slow-roll new inflation and chaotic inflation models. We do this within our approach to…
THE EFFECTIVE THEORY OF INFLATION IN THE STANDARD MODEL OF THE UNIVERSE AND THE CMB+LSS DATA ANALYSIS
- Physics
- 2009
Inflation is part of the Standard Model of the Universe supported by CMB and large scale structure LSS datasets. This review presents new developments of inflation in three main chapters. (I): The…
Non-parametric reconstruction of the primordial power spectrum at horizon scales from WMAP data
- Mathematics
- 2006
We extend to large scales a method proposed in previous work that reconstructs non-parametrically the primordial power spectrum from cosmic microwave background data at high resolution. The…
Considerations in optimizing CMB polarization experiments to constrain inflationary physics
- Physics
- 2005
We quantify the limiting factors in optimizing current-technology cosmic microwave background (CMB) polarization experiments to learn about inflationary physics. We consider space-based,…
Weak lensing and CMB: Parameter forecasts including a running spectral index
- Physics
- 2004
We use statistical inference theory to explore the constraints from future galaxy weak lensing (cosmic shear) surveys combined with the current CMB constraints on cosmological parameters, focusing…

New constraints on inflation from the cosmic microwave background
- Physics
- 2000
The recent data from the BOOMERANG and MAXIMA-1 balloon flights have marked the beginning of the precision era of cosmic microwave background (CMB) anisotropy measurements. We investigate the…
Inflationary gravity waves in light of recent cosmic microwave background anisotropies data
- Physics
- 2003
One of the major predictions of inflation is the existence of a stochastic background of cosmological gravitational waves (GW). These gravitational waves can induce significant temperature…
Reconstructing the inflaton potential—an overview
- Environmental Science
- 1997
The authors review the relation between the inflationary potential and the spectra of density waves (scalar perturbations) and gravitational waves (tensor perturbations) produced, with particular…
Cosmological parameter estimation and the inflationary cosmology
- Physics
- 2002
We consider approaches to cosmological parameter estimation in the inflationary cosmology, focusing on the required accuracy of the initial power spectra. Parametrizing the spectra, for example by…
Cosmological parameters from CMB and other data: A Monte Carlo approach
- Physics
- 2002
We present a fast Markov chain Monte Carlo exploration of cosmological parameter space. We perform a joint analysis of results from recent cosmic microwave background ~CMB! experiments and provide…
Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant

We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 " z " 0.62. The luminosity distances of these objects are determined by methods that…
Inflationary universe: A possible solution to the horizon and flatness problems
- Physics
- 1981
The standard model of hot big-bang cosmology requires initial conditions which are problematic in two ways: (1) The early universe is assumed to be highly homogeneous, in spite of the fact that…
