VLBA SiO maser maps of the star OH 44.8-2.3
SiO maser emission occurs in the extended atmosphere of evolved stars and can be studied at high angular resolution. As compact, high-brightness components they can be used as... -
70um-1.2mm and N_2_H+ maps of IRDC18454 (W43)
The earliest stages of high-mass star formation are still poorly characterized. Densities, temperatures and kinematics are crucial parameters for simulations of high-mass star... -
Large Quasar Astrometric Catalogue 2 (LQAC-2)
First of all we make a substantial review of the definitions and properties of quasars and AGN (Active Galactic Nuclei), the differenciation of these objects being unclear in... -
Coalsack CO maps
The large Coalsack dark cloud is one of the most prominent southern starless clouds, which is even visible to the naked eye. Furthermore, it is one of the rare molecular clouds... -
HCOOCH3 map of Orion-KL
The Orion Kleinmann-Low nebula (Orion-KL) is a complex region of star formation. Whereas its proximity allows studies on a scale of a few hundred AU, spectral confusion makes it... -
Inner Galaxy HII regions
We report simultaneous H110{alpha} and H_2_CO line observations with the 25m radio telescope of Nanshan station toward 251 HII regions. We used the H110{alpha} line to establish... -
Clumps in W31 from CO and 875um observations
High-mass star formation has been a very active field over the past decade; however, most studies have targeted regions of luminosities between 10^4^ and 10^5^L_{sun}. In... -
Megamaser detection in Seyfert galaxies
We revisit the relation between H_2_O maser detection rate and nuclear obscuration for a sample of 114 Seyfert galaxies, drawn from the CfA, 12um and IRAS F25/F60 catalogs.... -
Catalog of high extinction clouds
The earliest phases of massive star formation are found in cold and dense infrared dark clouds (IRDCs). Since the detection method of IRDCs is very sensitive to the local... -
^12^C^18^O(3-2) map of rho Oph A
The large submillimetre map of rho Oph A in the ^12^C^18^O(3-2) line, obtained with the APEX 12m telescope, covers 10' in RA by 5' in DE, sampled on a rectangular grid, aligned... -
HI observations of 2MASS galaxies in ZoA
A pilot survey has been made to obtain 21cm HI emission line profiles for 197 objects in the zone of avoidance (ZoA) that were classified as galaxies in the 2MASS all-sky... -
Parkes HI observations behind Milky Way II
As part of our programme to map the large-scale distribution of galaxies behind the southern Milky Way, we observed 314 optically-selected, partially-obscured galaxies in the... -
Radio maps of Infrared Dark Cloud 18223-3
We examine an Infrared Dark Cloud (IRDC) at high spatial resolution as a means to study rotation, outflow, and infall at the onset of massive star formation. The IRDC 18223-3... -
IRDC 19175-4 and IRDC 19175-5 turbulence maps
The aims is to characterizing the gas and dust properties prior to and in the neighborhood of active intermediate- to high-mass star formation. Two Infrared Dark Clouds (IRDCs),... -
Rotational spectrum of HCOO^13^CH_3_
Laboratory measurements and analysis of the microwave and millimeter-wave spectra of potential interstellar molecules are a prerequisite for their subsequent identification by... -
IRAS 05345+3157 mm high-angular resolution maps
To better understand the initial conditions of the high-mass star formation process, it is crucial to study at high-angular resolution the morphology, the kinematics, and... -
^12^CO(2-1) map of NGC 2264-C
The role played by protostellar feedback in clustered star formation is still a matter of debate. In particular, protostellar outflows have been proposed as a source of... -
CO maps of three lensed submillimetre galaxies
Submillimetre galaxies (SMGs) are distant, dusty galaxies undergoing star formation at prodigious rates. Recently there has been major progress in understanding the nature of... -
Large Quasar Astrometric Catalogue (LQAC)
The very large and increasing number of quasars reckoned from various sky surveys leads to a large quantity of data which brings various and inhomogeneous information in the... -
M83 volume densities of giant molecular clouds
Using observed GALEX far-ultraviolet (FUV) fluxes and VLA images of the 21-cm HIcolumn densities, along with estimates of the local dust abundances, we measure the volume...
