The primordial deuterium abundance: subDLA system at towards the QSO J1444+2919
S. A. Balashev, E. O. Zavarygin, A. V. Ivanchik +2
We report a new detection of neutral deuterium in the sub Damped Lyman Alpha system with low metallicity [O/H]\,=\, at towards QSO~J\,14442…
Effect of a partial coverage of quasar broad-line regions by intervening H-bearing clouds
Dmitrii Ofengeim, Sergei Balashev, Aleksandr Ivanchik +2
We consider the effect of a partial coverage of quasar broad-line regions (QSO BLRs) by intervening H-bearing clouds when a part of quasar (QSO) radiation passes by a cloud not…
Spectral distortions of the CMB dipole
S. A. Balashev, E. E. Kholupenko, J. Chluba +2
We consider the distortions of the cosmic microwave background (CMB) dipole anisotropy related to the primordial recombination radiation (PRR) and primordial - and -distortio…
Partial covering of emission regions of Q 0528-250 by intervening H clouds
V. V. Klimenko, S. A. Balashev, A. V. Ivanchik +5
We present an analysis of the molecular hydrogen absorption system at z = 2.811 in the spectrum of the blazar Q0528-250. We demonstrate that the molecular cloud does no…
Neutral chlorine and molecular hydrogen at high redshift
S. A. Balashev, P. Noterdaeme, V. V. Klimenko +5
Chlorine and molecular hydrogen are known to be tightly linked together in the cold phase of the local interstellar medium through rapid chemical reactions. We present here the fir…
