Primordial clouds under the influence of background radiation field
نویسنده
چکیده
Our goal is to study the effects of the UV radiation from the first stars, quasars and hypothetical Super Heavy Dark Matter (SHDM) particle decays on the formation of primordial bound objects in the Universe. We trace the evolution of a spherically symmetric density perturbation in the Lambda Cold Dark Matter and MOND model, solving the frequencydependent radiative transfer equation, non-equilibrium chemistry, and onedimensional gas hydrodynamics. We concentrate on the destruction and formation processes of the H2 molecule, which is the main coolant in the primordial objects.

Primordial Star Formation under Far-Ultraviolet Radiation
Thermal and chemical evolution of primordial gas clouds irradiated with farultraviolet (FUV; hν < 13.6 eV) radiation is investigated. In clouds irradiated by intense FUV radiation, sufficient hydrogen molecules to be important for cooling are never formed. However, even without molecular hydrogen, if the clouds are massive enough, they start collapsing via atomic hydrogen line cooling. Such clo...
متن کاملThe primordial baryonic clouds and their contribution to the CMB anisotropy and polarization formation
We discuss possible distortions of the ionization history of the Universe in the model with small scale baryonic clouds. The corresponding scales of the clouds are much smaller than the typical galactic mass scales. These clouds are considered in a framework of the cosmological model with the isocurvature and adiabatic perturbations. In this model the baryonic clouds do not influence on the cos...
متن کاملCollapse of Primordial Clouds II. The Role of Dark Matter
In this article we extend the study performed in our previous article on the collapse of primordial objects. We here analyze the behavior of the physical parameters for clouds ranging from 107M⊙ to 10 15 M⊙. We studied the dynamical evolution of these clouds in two ways: purely baryonic clouds and clouds with non-baryonic dark matter included. We start the calculations at the beginning of the r...
متن کاملFormation of Primordial Galaxies under UV background Radiation
The pancake collapse of pregalactic clouds under UV background radiation is explored with a one-dimensional sheet model. Here, attention is concentrated on elucidating the basic physics on the thermal evolution of pregalactic clouds exposed to diffuse UV radiation. So, we treat accurately the radiation transfer for the ionizing photons, with solving chemical reactions regarding hydrogen molecul...
متن کاملCollapse of Low Mass Clouds in the Presence of UV Radiation Field
The collapse of marginally Jeans unstable primordial gas clouds in the presence of UV radiation field is discussed. Assuming that the dynamical collapse proceeds approximately in an isothermal self-similar fashion, we investigate the thermal evolution of collapsing central core until H2 cooling dominates photoheating and the temperature drops to below 10K. Consequently, the mass of the cooled c...
