We present results from spectroscopic observations with X-shooter at the Very Large
Telescope of seven H2-bearing damped Lyman-α systems (DLAs) at high redshifts (z abs∼ …

We present a systematic study of deuterated molecular hydrogen (HD) at high redshift,
detected in absorption in the spectra of quasars. We present four new identifications of HD …

We present the results of an analysis of the physical conditions (number density, intensity of
UV field, kinetic temperature) in the cold H2-bearing interstellar medium of local and high …

We present both a disc-wind model on the optical/ultraviolet (UV) emission continuum and
cloudy modelling on the spectral lines of the tidal disruption event (TDE) intermediate …

We present a semi-analytical description of the relative hydrogen deuteride (HD)/H2
abundance in the diffuse interstellar medium. We found three asymptotics of the relative …

We report the serendipitous detection of an H 2-bearing damped Lyα absorber at z= 0.576 in
the spectrum of the QSO J0111–0316 in the Cosmic Ultraviolet Baryon Survey …

Studies measuring the chemical abundances of the neutral gas in star-forming galaxies
(SFGs) require ionization correction factors (ICFs) to accurately measure their metal …

We present the results of a spectroscopic analysis of extremely strong damped Lyα
absorbers (ESDLAs; log N (HI)≳ 21.7) observed with the medium resolution spectrograph, X …

We report the first detection of multiphase gas within a quiescent galaxy beyond z≈ 0. The
observations use the brighter image of doubly lensed QSO HE 0047− 1756 to probe the …

The cosmic-ray (CR) ionization rate (ζ, s− 1) plays an important role in the interstellar
medium. It controls ion–molecular chemistry and provides a source of heating. Here we …
