Hunting for Metals Using XQ-100 Legacy Survey Composite Spectra
S. Perrotta, V. D'Odorico, F. Hamann +10
We investigate the NV absorption signal along the line of sight of background quasars, in order to test the robustness of the use of this ion as criterion to select intrinsic (i.e.…
Infrared molecular hydrogen lines in GRB host galaxies
K. Wiersema, A. Togi, D. Watson +12
Molecular species, most frequently H_2, are present in a small, but growing, number of gamma-ray burst (GRB) afterglow spectra at redshifts z~2-3, detected through their rest-frame…
Stellar masses, metallicity gradients and suppressed star formation revealed in a new sample of absorption selected galaxies
N. H. P. Rhodin, L. Christensen, P. Møller +2
Context. Absorbing galaxies are selected via the detection of characteristic absorption lines which their gas-rich media imprint in the spectra of distant light-beacons. The proxim…
ALMA observations of a metal-rich damped Lyα absorber at z = 2.5832: evidence for strong galactic winds in a galaxy group
J. P. U. Fynbo, K. E. Heintz, M. Neeleman +7
We report on the results of a search for CO(3-2) emission from the galaxy counterpart of a high-metallicity Damped Ly-alpha Absorber (DLA) at z=2.5832 towards the quasar Q0918+1636…
Unidentified quasars among stationary objects from Gaia DR2
K. E. Heintz, J. P. U. Fynbo, E. Høg +5
We here apply a novel technique selecting quasar candidates purely as sources with zero proper motions in the Gaia data release 2 (DR2). We demonstrate that this approach is highly…
A quasar hiding behind two dusty absorbers. Quantifying the selection bias of metal-rich, damped Lyman-alpha absorption systems
K. E. Heintz, J. P. U. Fynbo, C. Ledoux +6
The cosmic chemical enrichment as measured from damped Ly absorbers (DLAs) will be underestimated if dusty and metal-rich absorbers have evaded identification. Here we report th…
