Constraints on Cosmological Parameters from the Lyα Forest Power Spectrum and COBE-DMR
We combine COBE-DMR measurements of cosmic microwave background (CMB) anisotropy with a recent measurement of the mass power spectrum at redshift z = 2.5 from Lyα forest data to derive constraints on cosmological parameters and test the inflationary cold dark matter (CDM) scenario of structure formation. By treating the inflationary spectral index n as a free parameter, we are able to find succ...
متن کاملPower Spectrum Independent Constraints on Cosmological Models †
A formalism is presented that allows cosmological experiments to be tested for consistency, and allows a simple frequentist interpretation of the resulting significance levels. As an example of an application, this formalism is used to place constraints on bulk flows of galaxies using the results of the microwave background anisotropy experiments COBE and SP91, and a few simplifying approximati...
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 کاملConstraints on Cosmological Parameters from Maxima-1
We set new constraints on a seven-dimensional space of cosmological parameters within the class of inflationary adiabatic models. We use the angular power spectrum of the cosmic microwave background measured over a wide range of ` in the first flight of the MAXIMA balloon-borne experiment (MAXIMA-1) and the low ` results from COBE/DMR. We find constraints on the total energy density of the univ...
متن کاملConstraints from the Lyman Α Forest Power Spectrum
We use published measurements of the transmission power spectrum of the Lyman α forest to constrain several parameters that describe cosmology and thermal properties of the intergalactic medium (IGM). A 6 parameter grid is constructed using Particle-Mesh dark matter simulations together with scaling relations to make predictions for the gas properties. We fit for all parameters simultaneously a...
