Cold diffuse interstellar medium of Magellanic Clouds: II. Physical conditions from excitation of CI and H
D. N. Kosenko, S. A. Balashev, V. V. Klimenko
We present a comprehensive study of the excitation of CI fine-structure levels along 57 sight lines in the Large and Small Magellanic Clouds. The sight lines were selected by the d…
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…
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…
Physical conditions in diffuse interstellar medium of local and high redshift galaxies: measurements based on excitation of H rotational and CI fine-structure levels
V. V. Klimenko, S. A. Balashev
We present results of analysis of physical conditions (number density, intensity of UV field, kinetic temperature) in the cold H-bearing interstellar medium of local and high r…
X-shooter observations of strong H-bearing DLAs at high redshift
S. A. Balashev, V. V. Klimenko, P. Noterdaeme +6
We present results from spectroscopic observations with X-shooter at the Very Large Telescope of seven H2-bearing DLAs at high redshifts (z). These DLAs were…
