Particle Physics Foundations of Dark Matter, Dark Energy, and Inflation (3/3)
/ Kolb, Edward W (speaker) (University of Chicago)
Ninety-five percent of the present mass-energy density of the Universe is dark. Twenty-five percent is in the form of dark matter holding together galaxies and other large scale structures, and 70% is in the form of dark energy driving an accelerated expansion of the universe. [...]

The Cosmological Standard Model and Its Implications for Beyond the Standard Model of Particle Physics
/ Kolb, Edward W (speaker) (University of Chicago)
While the cosmological standard model has many notable successes, it assumes 95% of the mass-energy density of the universe is dark and of unknown nature, and there was an early stage of inflationary expansion driven by physics far beyond the range of the particle physics standard model. In the colloquium I will discuss potential particle-physics implications of the standard cosmological model..

Latest inflation model constraints from cosmic microwave background measurements
/ Kinney, William H (SUNY, Buffalo) ; Kolb, Edward W (Chicago U., EFI ; KICP, Chicago) ; Melchiorri, Alessandro (INFN, Rome ; Rome U.) ; Riotto, Antonio (CERN ; INFN, Padua)
We present new cosmological constraints on single-field inflation in light of the Wilkinson Microwave Anisotropy Probe satellite mission five-year results (WMAP5). We find that the cosmic microwave background data are quite consistent with a Harrison-Zel'dovich primordial spectrum with no running and zero tensor amplitude..

We present an update of cosmological constraints on single-field inflation in light of the Wilkinson Microwave Ansiotropy Probe satellite mission five-year results (WMAP5). We find that the cosmic microwave background data are quite consistent with a Harrison-Zel'dovich primordial spectrum with no running and zero tensor amplitude. [...]

The dark universe : dark matter and dark energy
/ Kolb, Edward W (speaker) (Chicago Univ., Dep. of Astronomy and Astrophys.)
According to the standard cosmological model, 95% of the present mass density of the universe is dark: roughly 70% of the total in the form of dark energy and 25% in the form of dark matter. In a series of four lectures, I will begin by presenting a brief review of cosmology, and then I will review the observational evidence for dark matter and dark energy. [...]

On cosmological observables in a swiss-cheese universe
/ Marra, Valerio (Padua U. ; INFN, Padua ; Chicago U., Astron. Astrophys. Ctr.) ; Kolb, Edward W. (Chicago U., Astron. Astrophys. Ctr. ; Chicago U., EFI ; Chicago U., KICP) ; Matarrese, Sabino (Padua U. ; INFN, Padua) ; Riotto, Antonio (CERN ; INFN, Padua)
Photon geodesics are calculated in a swiss-cheese model, where the cheese is made of the usual Friedmann-Robertson-Walker solution and the holes are constructed from a Lemaitre-Tolman-Bondi solution of Einstein's equations. The observables on which we focus are the changes in the redshift, in the angular-diameter--distance relation, in the luminosity-distance--redshift relation, and in the corresponding distance modulus.

Inflation model constraints from the Wilkinson Microwave Anisotropy Probe three-year data
/ Kinney, William H. (SUNY, Buffalo) ; Kolb, Edward W. (Fermilab ; Chicago U., Astron. Astrophys. Ctr.) ; Melchiorri, Alessandro (Rome U. ; INFN, Rome) ; Riotto, Antonio (CERN)
We extract parameters relevant for distinguishing among single-field inflation models from the Wilkinson Microwave Anisotropy Probe (WMAP) three-year data set, and also from WMAP in combination with the Sloan Digital Sky Survey (SDSS) galaxy power spectrum. Our analysis leads to the following conclusions: 1) the Harrison--Zel'dovich model is consistent with both data sets at a 95% confidence level; 2) there is no strong evidence for running of the spectral index of scalar perturbations; 3) Potentials of the form V \propto \phi^p are consistent with the data for p = 2, and are marginally consistent with the WMAP data considered alone for p = 4, but ruled out by WMAP combined with SDSS.
