Star-forming regions of the Aquila rift cloud complex. II. Turbulence in molecular cores probed by NH3 emission
S. A. Levshakov, C. Henkel, D. Reimers +1
(Abridged) Aims. We intend to derive statistical properties of stochastic gas motion inside the dense low mass star forming molecular cores traced by NH3(1,1) and (2,2) emission li…
Binaries discovered by the SPY project. III. HE2209-1444: a massive, short period double degenerate
C. A. Karl, R. Napiwotzki, G. Nelemans +4
In the course of our search for double degenerate (DD) binaries as potential progenitors of type Ia supernovae with the UVES spectrograph at the ESO VLT (ESO SN Ia Progenitor surve…
The Hamburg/RASS optical identification project
F. -J. Zickgraf, D. Engels, H. -J. Hagen +1
We use digitized Schmidt direct and prism plates taken for the northern hemisphere Hamburg Quasar Survey (HQS) to obtain optical identifications for all high galactic latitude X-ra…
An Automated Search for Metal-Poor Halo Stars in the Hamburg/ESO Objective-Prism Survey
Norbert Christlieb, Lutz Wisotzki, Dieter Reimers +3
An automated search for metal-poor stars is carried out in the course of the Hamburg/ESO objective-prism survey (HES), which covers the full southern sky at Galactic latitudes |b|…
The QSO evolution derived from the HBQS and other complete QSO surveys
Fabio La Franca, Stefano Cristiani
An ESO Key programme dedicated to an Homogeneous Bright QSO Survey (HBQS) has been completed. 327 QSOs (Mb<-23, 0.3<z<2.2) have been selected over 555 deg^2 with 15<B<18.75. For B<…
