Non-Nucleosynthetic Constraints on the Baryon Density and Other Cosmological Parameters
Because the baryon-to-photon ratio η10 is in some doubt, we drop nucleosynthetic constraints on η10 and fit the three cosmological parameters (h,ΩM, η10) to four observational constraints: Hubble parameter ho = 0.70± 0.15, age of the universe to = 14 +7 −2 Gyr, cluster gas fraction fo ≡ fGh 3/2 = 0.060 ± 0.006, and effective shape parameter Γo = 0.255 ± 0.017. Errors quoted are 1σ, and we assum...
متن کاملConstraints on cosmological parameters
A cosmological model with total density close to critical (and flat geometry), dominated by dark matter and dark energy of unknown nature, and consistent with the basic predictions of the inflationary scenario is a very good fit to a variety of cosmological probes: the anisotropy of the CMB, the large scale distribution of matter, the luminosity distance of high-redshift type Ia supernovae and ...
متن کاملThe Baryon Density Through The ( Cosmological ) Ages
The light element abundances probe the baryon density of the universe within a few minutes of the Big Bang. Of these relics from the earliest universe, deuterium is the baryometer of choice. By comparing its primordial abundance inferred from observations with that predicted by Big Bang Nucleosynthesis (BBN), the early universe baryon density is derived. This is then compared to independent est...
متن کامل0 Global Constraints on Key Cosmological Parameters
Data from Type Ia supernovae, along with X-ray cluster estimates of the universal baryon fraction and Big Bang Nucleosynthesis (BBN) determina-tions of the baryon-to-photon ratio, are used to provide estimates of several global cosmological parameters at epochs near zero redshift. We show that our estimate of the present baryon density is in remarkably good agreement with that inferred from BBN...
متن کاملMicrowave Background Constraints on Cosmological Parameters
We use a high-accuracy computational code to investigate the precision with which cosmological parameters could be reconstructed by future cosmic microwave background experiments. We focus on the two planned satellite missions: MAP and Planck. We identify several parameter combinations that could be determined with a few percent accuracy with the two missions, as well as some degeneracies among...
