28SiO in O-rich evolved stars
We present simultaneous observations of several rotational lines of ^28^SiO in the v=1, 2, 3, and 4 vibrationally excited states toward O-rich evolved stars. All the data were... -
OH maser emission from IRAS sources
A high-sensitivity search for water maser emission at 22.2 GHz has been performed on a sample of 91 IRAS point sources at high-latitudes. The aim of the survey is to verify if... -
5cm OH masers survey
We have undertaken a comprehensive search for 5 cm OH masers in regions visible from Effelsberg with the 100-m telescope (i.e., those with declinations above -29^o^). Our sample... -
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... -
OH maser from semiregular variables
We have made a high sensivity (~0.15Jy) search in the OH main-lines for maser emission from a sample of 181 semiregular variables. -
Semiregular variables H2O maser
107 semiregular variables of spectral type M have been observed in the H2O 6(16)-5(23) line at 22.235GHz with the 100m Effelsberg radio telescope and maser emission has been... -
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... -
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... -
NGC6334I-MM1 system watermasers spatiokinematics
Following an eruptive accretion event in NGC6334I-MM1, flares in the various maser species, including water masers, were triggered. We report the observed relative proper motion... -
Methanol masers in HII regions
As the recent publication by Breen et al. (2013MNRAS.435..524B) found, Class II methanol masers are exclusively associated with high mass star forming regions. Based on the... -
H_2_O Southern Galactic Plane Survey, HOPS. II
The H2O Southern Galactic Plane Survey (HOPS) has mapped a 100{deg} strip of the Galactic plane (-70{deg}>l>30{deg}, |b|<0.5{deg}) using the 22m Mopra antenna at 12mm... -
A 95 GHz Survey of Methanol Masers
A 95GHz survey of methanol emission in the 8_0_-7_1_A^+^ transition was conducted with the 20-m radio telescope at Onsala. Twenty-six new sources were detected in the emission... -
Thermal Methanol from 33 Clouds at 48 GHz
A search for thermal emission in the 1_0_-0_0_A^+^ methanol line was made at a frequency of 48.4GHz toward many celestial molecular clouds. The line was found in 33 clouds, and... -
95GHz class I methanol maser survey
We report a survey with the Purple Mountain Observatory 13.7m radio telescope for class I methanol masers from the 95GHz (8_0_-7_1_A^+^) transition. Two hundred and fourteen... -
VLA obs. of the H2O maser source G25.65+1.05
The source G25.65+1.05 (RAFGL7009S, IRAS 18316-0602) is the least studied of the three regions of massive star formation known to show exceptionally powerful H_2_O maser bursts.... -
Methanol (CH_3_OH) and OH masers in NGC 6334I
We report the first sub-arcsecond VLA imaging of 6GHz continuum, methanol maser, and excited-state hydroxyl maser emission toward the massive protostellar cluster NGC 6334I... -
The Megamaser Cosmology Project. X.
We present high-resolution (submas) Very Long Baseline Interferometry maps of nuclear H_2_O megamasers for seven galaxies. In UGC 6093, the well-aligned systemic masers and... -
BGPS. XIV. Molecular cloud clumps GBT obs.
We sort 4683 molecular clouds between 10{deg}<l<65{deg} from the Bolocam Galactic Plane Survey based on observational diagnostics of star formation activity: compact... -
Polarized SiO masers of VX Sgr
We present Submillimeter Array observations of high-frequency SiO masers around the supergiant VX Sgr and the semi-regular variable star W Hya. The J=5-4, v=1^28^SiO and... -
Water maser emission in five AGNs
We report the discovery of water maser emission in five active galactic nuclei (AGNs) with the 100m Green Bank Telescope (GBT). The positions of the newly discovered masers,...
