The Antares emission nebula and mass loss of alpha Sco A
D. Reimers, H. -J. Hagen, R. Baade +1
The Antares nebula is a peculiar emission nebula seen in numerous Fe II lines and in radio free-free emission, probably associated with the H II region caused by alpha Sco B in the…
HE 0515-4414 - an unusual sub-damped Ly alpha system revisited
R. Quast, D. Reimers, R. Baade
Using STIS and VLT UVES observations we have examined the ionization, abundances, and differential dust depletion of metals, the kinematic structure, and the physical conditions in…
The UV spectrum of HS1700+6416 II. FUSE observations of the HeII Lyman alpha forest
C. Fechner, D. Reimers, G. A. Kriss +11
We present the far-UV spectrum of the quasar HS1700+6416 taken with FUSE. This QSO provides the second line of sight with the HeII absorption resolved into a Ly alpha forest struct…
FUSE observations of the HeII Lyman alpha forest towards HS1700+6416
D. Reimers, C. Fechner, G. Kriss +5
We present FUSE observations of the HeII Lyman alpha forest in the redshift range 2.3 < z < 2.7 towards HS1700+6416. Between October 2002 and February 2003, the brightness of the Q…
Evolution strategies applied to the problem of line profile decomposition in QSO spectra
R. Quast, R. Baade, D. Reimers
We describe the decomposition of QSO absorption line ensembles applying an evolutionary forward modelling technique. The modelling is optimized using an evolution strategy (ES) bas…
The associated system of HE2347-4342
Cora Fechner, Robert Baade, Dieter Reimers
We present an analysis of the complex associated system of the high-redshift QSO HE2347-4342. Absorption features of HI, CIII, CIV, NV, and OVI with up to 16 components occur in th…
