A New Precise Determination of the Primordial Abundance of Deuterium: Measurement in the metal-poor sub-DLA system at z=3.42 towards quasar J1332+0052
P. A. Kislitsyn, S. A. Balashev, M. T. Murphy +3
The theory of Big Bang nucleosynthesis, coupled with an estimate of the primordial deuterium abundance (D/H)_pr, offers insights into the baryon density of the Universe. Independen…
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, , is a prediction of the standard cosmological 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 is a powerful probe of the early Universe. The most common way to determine is analyses of observations of…
Directional Radiation and Photodissociation Regions in Molecular Hydrogen Clouds
S. A. Balashev, D. A. Varshalovich, A. V. Ivanchik
Some astrophysical observations of molecular hydrogen point to a broadening of the velocity distribution for molecules at excited rotational levels. This effect is observed in both…
