Time-Dependent Corrections to the Ly-alpha Escape Probability During Cosmological Hydrogen Recombination
J. Chluba, R. A. Sunyaev
We consider the effects connected with the detailed radiative transfer during the epoch of cosmological recombination on the ionization history of our Universe. We focus on the esc…
Evolution of low-frequency features in the CMB spectrum due to stimulated Compton scattering and Doppler-broadening
J. Chluba, R. A. Sunyaev
We discuss a new solution of the Kompaneets-equation for physical situations in which low frequency photons, forming relatively narrow spectral details, are Compton scattered in an…
Lines in the cosmic microwave background spectrum from the epoch of cosmological helium recombination
J. A. Rubino-Martin, J. Chluba, R. A. Sunyaev
The main goal of this work is to calculate the contributions to the cosmological recombination spectrum due to bound-bound transitions of helium. We show that due to the presence o…
The Richness and Beauty of the Physics of Cosmological Recombination
R. A. Sunyaev, J. Chluba
The physical ingredients to describe the epoch of cosmological recombination are amazingly simple and well-understood. This fact allows us to take into account a very large variety…
Is there a need and another way to measure the Cosmic Microwave Background temperature more accurately?
J. Chluba, R. A. Sunyaev
The recombination history of the Universe depends exponentially on the temperature, T_0, of the cosmic microwave background. Therefore tiny changes of T_0 are expected to lead to s…
Two-photon transitions in hydrogen and cosmological recombination
J. Chluba, R. A. Sunyaev
We study the two-photon process for the transitions ns --> 1s and nd --> 1s in hydrogen up to large n. For n<=20 we provide simple analytic fitting formulae to describe the non-res…
