Estimating the impact of recombination uncertainties on the cosmological parameter constraints from cosmic microwave background experiments
J. A. Rubino-Martin, J. Chluba, W. A. Fendt +1
[Abridged] We use our most recent training set for the RICO code to estimate the impact of recombination uncertainties on the posterior probability distributions which will be obta…
Could the Cosmological Recombination Spectrum Help Us Understand Annihilating Dark Matter?
J. Chluba
In this paper we explore the potential effects of DM annihilations on the cosmological recombination spectrum. With this example we want to demonstrate that the cosmological recomb…
Cosmological recombination: feedback of helium photons and its effect on the recombination spectrum
J. Chluba, R. A. Sunyaev
In this paper we consider the re-processing of high frequency photons emitted by HeII and HeI during the epoch of cosmological recombination by HeI and HI. We demonstrate that, in…
Signals From the Epoch 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…
Cosmological Hydrogen Recombination: influence of resonance and electron scattering
J. Chluba, R. A. Sunyaev
In this paper we consider the effects of resonance and electron scattering on the escape of Lyman alpha photons during cosmological hydrogen recombination. We pay particular attent…
Ly alpha escape during cosmological hydrogen recombination: the 3d-1s and 3s-1s two-photon processes
J. Chluba, R. A. Sunyaev
We give a formulation of the radiative transfer equation for Lyman alpha photons which allows us to include the two-photon corrections for the 3s-1s and 3d-1s decay channels during…
