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.…
Discovery of CO absorption at z=0.05 in G0248+430
F. Combes, N. Gupta, G. I. G. Jozsa +1
Absorption lines in front of distant quasars are quite rare in the millimeter domain. They can however bring a very useful and complementary information to emission lines. We repor…
VLT/UVES observations of extremely strong intervening damped Lyman-alpha systems: Molecular hydrogen and excited carbon, oxygen and silicon at log N(HI)=22.4
P. Noterdaeme, R. Srianand, H. Rahmani +5
We present a detailed analysis of three extremely strong intervening DLAs (log N(HI)>=21.7) observed towards quasars with VLT/UVES. We measure overall metallicities of [Zn/H]~-1.2,…
21-cm absorbers at intermediate redshifts
N. Gupta, R. Srianand, P. Petitjean +2
Damped Lyman-alpha systems (DLAs) seen in the spectra of high-z QSOs allow us to probe the physical conditions in protogalaxies. Our understanding of physical conditions in DLAs at…
