HD/H2 Molecular Clouds in the Early Universe: The Problem of Primordial Deuterium
S. A. Balashev, A. V. Ivanchik, D. A. Varshalovich
We have detected new HD absorption systems at high redshifts, z_abs=2.626 and z_abs=1.777, identified in the spectra of the quasars J0812+3208 and Q1331+170, respectively. Each of…

Large-scale periodicity in the distribution of QSO absorption-line systems
A. I. Ryabinkov, A. D. Kaminker
The spatial-temporal distribution of absorption-line systems (ALSs) observed in QSO spectra within the cosmological redshift interval z = 0.0--4.3 is investigated on the base of ou…
