Rapid HeII->HeI recombination and radiation concerned with this process

E. E. Kholupenko, A. V. Ivanchik, D. A. Varshalovich

Recombination of the primordial helium plasma (HeII->HeI, $z ≃ 1500 - 3000$ ) is considered. This process has an effect on the CMBR anisotropy and CMBR spectrum distortion. In…

The redshift distribution of absorption-line systems in QSO spectra

A. I. Ryabinkov, A. D. Kaminker, D. A. Varshalovich

A statistical analysis of the space-time distribution of absorption-line systems (ALSs) observed in QSO spectra within the cosmological redshift interval $z$ =0.0--3.7 is carried ou…
