Recombination Induced Softening and Reheating of the Cosmic Plasma
نویسندگان
چکیده
The atomic recombination process leads to a softening of the matter equation of state as reflected by a reduced generalized adiabatic index, with accompanying heat release. We study the effects of this recombination softening and reheating of the cosmic plasma on the ionization history, visibility function, Cold Dark Matter (CDM) transfer function, and the Cosmic Microwave Background (CMB) spectra. The resulting modification of the CMB spectrum is 1/10 of WMAP’s current error and is comparable to PLANCK’s error. Therefore, this effect should be considered when data with higher accuracy are analysed.

متن کاملComment on ‘Recombination induced softening and reheating of the cosmic plasma’
Leung, Chan & Chu (2004) claimed that a previously neglected reheating effect makes a small but noticeable change to the process of cosmological recombination. We revisit this effect by considering a system consisting of both radiation and ionizing gas under adiabatic expansion. In the thermal equilibrium limit, due to the huge radiation background, only a fraction about 10 of the heat released...
متن کاملThe Cosmic Microwave Background Radiation
We summarize the theoretical and observational status of the study of the Cosmic Microwave Background radiation. Its thermodynamic spectrum is a robust prediction of the Hot Big Bang cosmology and has been confirmed observationally. There are now 76 observations of Cosmic Microwave Background anisotropy, which we present in a table with references. We discuss the theoretical origins of these an...
متن کاملCausality and Primordial Tensor Modes
We introduce the real space correlation function of B-mode polarization of the cosmic microwave background (CMB) as a probe of superhorizon tensor perturbations created by inflation. By causality, any non-inflationary mechanism for gravitational wave production after reheating, like global phase transitions or cosmic strings, must have vanishing correlations for angular separations greater than...
متن کاملDielectronic Recombination: an Overview of Theory and Experiment, and Some Astrophysical Implications
The status of dielectronic recombination (DR) rate coefficients used for modeling cosmic plasmas is discussed. A brief overview of theoretical and experimental studies of DR is given. Results are shown which demonstrate the astrophysical importance of accurate DR rates for studies of the intergalactic medium.
