Estimation of the CMB temperature from atomic C\,{\sc i} and molecular CO lines in the interstellar medium of early galaxies

V. V. Klimenko, A. V. Ivanchik, P. Petitjean +2

The linear increase of the cosmic microwave background (CMB) temperature with cosmological redshift, $T_{CMB} = T_{0} (1 + z)$ , is a prediction of the standard cosmological $Λ$ CDM…

A new determination of the primordial helium abundance using the analyses of HII region spectra from SDSS

O. A. Kurichin, P. A. Kislitsyn, V. V. Klimenko +2

The precision measurement of the primordial helium abundance $Y_{p}$ is a powerful probe of the early Universe. The most common way to determine $Y_{p}$ is analyses of observations of…

Influence of radiative pumping on the HD rotational level populations in diffuse molecular clouds of the interstellar medium

V. V. Klimenko, A. V. Ivanchik

We present a theoretical calculation of the influence of ultraviolet radiative pumping on the excitation of the rotational levels of the ground vibrational state for HD molecules u…
