HD/H ratio in the diffuse interstellar medium

S. A. Balashev, D. N. Kosenko

We present a semi-analytical description of the relative HD/H2 abundance in the diffuse interstellar medium. We found three asymptotics of the relative HD/H abundance for diffe…

Chemical enrichment and host galaxies of extremely-strong intervening DLAs towards quasars

A. Ranjan, P. Noterdaeme, J. -K. Krogager +5

We present the results from VLT/X-shooter spectroscopic observations of 11 extremely strong intervening damped Lyman-alpha absorbers (ESDLAs) initially selected as high N(Hi) (i.e.…

Jeans smoothing of the Ly forest absorption lines

K. N. Telikova, S. A. Balashev, P. S. Shternin

We investigate a contribution of the Jeans smoothing to the minimal width of Ly forest lines and discuss how the accounting for this additional broadening affects the inferred p…

Thermal state of the intergalactic medium at

K. N. Telikova, P. S. Shternin, S. A. Balashev

We present a new method to infer parameters of the temperature-density relation in the intergalactic medium in the post-reionization epoch at . This method is based on t…

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…

Proximate Molecular Quasar Absorbers: Excess of damped H2 systems at zabs~zQSO in SDSS DR14

P. Noterdaeme, S. Balashev, J. -K. Krogager +4

We present results from a search for strong H2 absorption systems proximate to quasars (zabs~zem) in the Sloan Digital Sky Survey (SDSS) Data Release 14. The search is based on the…
