Modeling primordial Gas in Numerical Cosmology
We have reviewed the chemistry and cooling behaviour of low-density (n < 104 cm−3) primordial gas and devised a cooling model wich involves 19 collisional and 9 radiative processes and is applicable for temperatures in the range (1K< T < 108K). We derived new fits of rate coefficients for the photo-attachment of neutral hydrogen, the formation of molecular hydrogen via H , charge exchange betwe...
متن کاملScale-free primordial cosmology
The large-scale structure of the Universe suggests that the physics underlying its early evolution is scalefree. This was the historic motivation for the Harrison-Zel’dovich-Peebles spectrum and for inflation. Based on a hydrodynamical approach, we identify scale-free forms for the background equation of state for both inflationary and cyclic scenarios and use these forms to derive predictions ...
متن کاملScientific Realism and Primordial Cosmology
We discuss scientific realism from the perspective of modern cosmology, especially primordial cosmology: i.e. the cosmological investigation of the very
متن کاملPrimordial gravitational waves and cosmology.
The observation of primordial gravitational waves could provide a new and unique window on the earliest moments in the history of the universe and on possible new physics at energies many orders of magnitude beyond those accessible at particle accelerators. Such waves might be detectable soon, in current or planned satellite experiments that will probe for characteristic imprints in the polariz...
متن کاملCosmic Walls and Filaments Formation in Modied Chaplygin Gas Cosmology
We want to study the perturbation growth of an initial seed of an ellipsoidal shape in Top-Hat collapse model of the structure formation in the Modied Chaplygin gas cosmology. Considering reasonable values of the constants and the parameters of the model under study, we can show that a very small deviation from spherical symmetry (ellipsoidal geometry) in the initial seed leads to a nal highly ...
