330-360GHz spectral lines of G 34.3+0.15. II.
Tables 5 and 6 present calculated column densities (in units of molecules per cm^2^) of various species in the ultracompact core (UCC), the compact core (CC) and the halo,... -
HI properties of spiral and irregular galaxies
We present the analysis of neutral hydrogen properties of 108 galaxies, based on short 21-cm observations with the Westerbork Synthesis Radio Telescope (WSRT). The results of... -
SiO production in interstellar shocks
We study the production of SiO in the gas phase of molecular outflows, through the sputtering of Si-bearing material in grains. The sputtering is driven by neutral particle... -
IR photometry of L1551/IRS5
We describe a new approach to the solution of the frequency-dependent stationary radiative transfer equation for axially-symmetric circumstellar dust disks. The method is... -
Maps of the 36 GHz methanol emission
We have used the Effelsberg 100-meter telescope to map the 36GHz 4_-1_->3_0_E methanol transition in galactic star forming regions where methanol masers were previously... -
Positions & proper motions of radio stars
The optical positions of 63 extragalactic nebulae measured in the frame defined by the annual series of Carlsberg Meridian Catalogues Nos 1-8 are compared with their VLBI radio... -
CO observations of clouds in IC 1396 region
^12^CO and ^13^CO (1-0) parameters are observed for selected clouds and cloud cores (or part of clouds) in the region of IC 1396 Cone search capability for table... -
HII Regions in M51
A deeper detection of the spiral structure of the Sbc galaxy M 51 is the main goal of this paper. New UV data in the 2000A range were obtained with a high altitude balloon of... -
Spectrophotometry of planetary nebulae
Spectrohotometric observations at high signal-to-noise ratio for a sample of 62 planetary nebulae are presented, together with the plasma and abundance analyses. The objects... -
PNe and HII in NGC 300
We report a search for planetary nebulae and H II regions in the central part of the late-type spiral NGC 300, using a CCD and the on-band/off-band filter technique. The total... -
H2O masers in HII regions
The results of a survey of 22.2GHz H2O maser emission towards a large sample of HII regions (427) detected in hydrogen recombination lines (Lockman) are presented. The sample... -
21cm obs. of galaxies in Psc-Per Supercl.
This paper presents the first results of a 21cm survey of newly discovered optically selected galaxies behind the Milky Way. We present 40 radial velocities of the new galaxies... -
Association of HII regions and IRAS PSC sources

OH maser survey of cool IRAS sources
The data are the results of a search for 1612MHz OH circumstellar masers in a colour limited sample of cool ORAS sources. Most of the observations were made at the Nancay radio... -
Radio observations of South. PN Candidates
IRAS sources having IR colours typical of planetary nebulae and located outside the Galactic bulge were observed in the radio continuum at 6cm with the Australian Compact Array... -

Radio continuum in Cygnus X region
The Cygnus X region has been observed at 408 and 1420 MHz with the Dominion Radio Astrophysical Observatory (DRAO), with an angular resolution of 3.5x5.2 and 1.0x1.5 arcmin.... -
Small-scale structures in HI hole of M33
Recent high-resolution HI observations of M33 reveal a large number of regions that are devoid of emission. We interpret these regions as holes formed by interstellar winds; a... -
HI data for 392 spiral galaxies
392 spiral galaxies with type Sb or later have been detected in the 21-cm line of neutral hydrogen with the Nancay radiotelescope, and among them 172 HI fluxes are obtained for...
