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... -
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),... -
A search for pre-biotic molecules
Low-noise, 0.8MHz resolution spectra around 90GHz towards four hot core sources: Orion KL, W51 e1/e2, S140, and W3(OH), are presented. The observations were performed using the... -
12CO outflows towards submm cores in Perseus
We present a search for outflows towards 51 submillimetre cores in Perseus. With consistently derived outflow properties from a large homogeneous dataset within one molecular... -
Dissipative structures of diffuse molecular gas
These maps are part of a large project aimed at analyzing the small scale morphology and velocity structure of the parsec-scale environment of a low mass dense core. The Polaris... -
Organic molecules in the Galactic center
We carried out a systematic study of the complex organic molecules CH_3_OH, C_2_H_5_OH, (CH_3_)2_O, HCOOCH_3, HCOOH, CH_3_COOH, H_2_CO, and CS toward 40 GC molecular clouds.... -
C^18^O/C^17^O near rho Oph
Observations of up to ten carbon monoxide (CO and isotopomers) transitions are presented to study the interstellar C^18^O/C^17^O ratio towards 21 positions in the nearby... -
Galactic emission at decimeter wavelengths
The diffuse galactic emission maps at decimeter wavelengths (408 MHz, Haslam et al., 1982A&AS...47....1H), (1420 MHz, Reich, 1982A&AS...48..219R, Reich & Reich... -
Galactic HII regions
The Master Catalog collects the information from 24 previously published lists and catalogs for 1442 Galactic HII regions. For each object, the Master Catalog quotes the... -
18-cm OH lines in comets
Since the apparition of comet Kohoutek 1973 XII, the 18-cm lines of the OH radical have been systematically observed in a number of comets with the Nancay radio telescope.... -
Optical positions of 55 radio stars at Yunnan Obs.
The observations by the photoelectric astrolabe at Yunnan Observatory relative to the Hipparcos Catalogue (Cat. ) and the optical positions of 55 radio stars were obtained from... -
Arcetri Catalog of H2O maser sources. Update.
We present a second update of the Arcetri Catalog of water masers (Comoretto et al., 1990A&AS...84..179C; Brand et al., 1994, Cat. ). The present study reports the results... -
HNCO in massive galactic dense cores
We surveyed 81 dense molecular cores associated with regions of massive star formation and Sgr A in the J_(K_-1_K_1_)=5_(05)-4_(04) and 10(010)-9_(09) lines of HNCO. Line... -
The {lambda}-Orionis ring in CO
The table shows clump parameters for 130 peaks in CO(J=1->0) emission detected in the Lambda-Orionis ring in the survey of Lang et al. (1998PASA...15...70L). The clumps were... -
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... -
