Publikováno v: Astronomy & Astrophysics. 440:767-773

We present the final data release of the high sensitivity lambda 21-cm neutral hydrogen survey of the sky south of delta < -25 degr. A total of 50980 positions lying on a galactic coordinate grid with points spaced by (Delta l, Delta b) = ((0.5 deg)/

Ca ii K interstellar observations towards early-type disc and halo stars - distances to intermediate- and high-velocity clouds

We compare existing high spectral resolution (R=40,000) CaII K observations towards 88 mainly B-type stars, and new observations at R=10,000 towards 3 stars, with 21-cm HI emission-line profiles, in order to search for optical absorption towards know

Publikováno v: Astronomy and Astrophysics Supplement Series. 142:35-40

This paper reports on a high sensitivity λ 21-cm neutral hydrogen survey of the sky south of δ ≤ -25°. A total of 50980 positions lying on a galactic coordinate grid with points spaced by (Δl, Δb) = (0°.5/cos b, 0°.5), were observed with the

Aims. We want to make a large-scale study of the morphology, kinematics, and origin of the HI, which surrounds the Sco-Cen association. Methods. We combine our high-sensitivity southern HI survey with the Leiden/Dwingeloo Survey, considering l = 240�

Observations towards early-type stars in the ESO-POP survey: II -- searches for intermediate and high velocity clouds

Autor: D. Silva, Peter M. W. Kalberla, Ian Hunter, Francis P. Keenan, Reinhard Hanuschik, Esteban Bajaja, R. Morras, J. V. Smoker, M. Arnal, W. G. L. Poppel, H. M. A. Thompson

We present CaII K and TiII optical spectra of early-type stars taken mainly from the UVES Paranal Observatory Project, plus HI 21-cm spectra from the Vila-Elisa and Leiden-Dwingeloo surveys, which are employed to obtain distances to intermediate and
