Galaxy counterparts of metal-rich damped Lyman-alpha absorbers - II. A solar-metallicity and dusty DLA at z_abs=2.58
J. P. U. Fynbo, C. Ledoux, P. Noterdaeme +14
[Abridged]. Here, we report on the discovery of the galaxy counterpart of the z_abs=2.58 DLA on the line-of-sight to the z=3.07 quasar SDSS J091826.16+163609.0. The galaxy counterp…
GRB 021004: Tomography of a gamma-ray burst progenitor and its host galaxy
A. J. Castro-Tirado, P. Möller, G. García-Segura +23
We analyse the distribution of matter around the progenitor star of gamma-ray burst GRB 021004 as well as the properties of its host galaxy with high-resolution echelle as well as…
Correction of Field Rotator-Induced Flat-Field Systematics - A Case Study Using Archived VLT-FORS Data
S. Moehler, W. Freudling, P. Moller +3
ESO's two FOcal Reducer and low dispersion Spectrographs (FORS) are the primary optical imaging instruments for the VLT. They are not direct-imaging instruments, as there are sever…
