ATCA obs. of ground-state OH masers
We report on high spatial resolution observations, using the Australia Telescope Compact Array (ATCA), of ground-state OH masers. These observations were carried out toward 196... -
CH_3_OH & OH line emission from Galactic center
Class I methanol masers are collisionally pumped and are generally correlated with outflows in star-forming sites in the Galaxy. Using the Very Large Array in its A-array... -
SiO and H2O maser survey toward AGB & post-AGB stars
Simultaneous observations of SiO(v=1,2,J=1-0) ^29^SiO(v=0,J=1-0) (43.122080GHz, 42.820587GHz and 42.879916GHz) and H_2_O(6_16_-5_23_) (22.235080GHz) maser lines were performed... -
H_2_O + CH_3_OH maser survey of Orion protostars
The results of a maser survey toward 99 protostars in the Orion molecular cloud complex are presented. The target sources are low-mass protostars identified from infrared... -
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... -
Full-polarization observations of OH masers
We present full-polarization VLBA maps of the ground-state, main-line, ^2^{Pi}3/2, J=3/2 OH masers in 18 Galactic massive star-forming regions. This is the first large... -
OH maser IRAS and MSX observations
We present OH maser observations at 1612, 1665, 1667, and 1720MHz for 86 likely post-asymptotic giant branch (post-AGB) stars selected from a survey of 1612MHz maser sources in... -
H2O masers in W49 North and Sagittarius B2
Using the Very Large Array (VLA) of the National Radio Astronomy Observatory in the A and B configurations, we have obtained simultaneous high-resolution observations of both... -
CH_3_OH 7_0_-6_1_ A^+^ maser sources
We present a Very Large Array survey of 44 massive star-forming regions in the 44GHz 7_0_-6_1_ A^+^ methanol transition; 37 fields showed maser emission. Thirty-one sources were... -
OH observations of Arecibo OH/IR stars
The Arecibo 1612MHz survey of a complete sample of color-selected IRAS sources with 25{mu}m fluxes S(25)>2 Jy detected 393 OH/IR stars. A complementary 1667 and 1665MHz OH... -
SiO maser sources
The observations in the 28SiO J=1-0 v=1, J=1-0 v=2 lines and the 29SiO J=1-0, v=0 lines were simultaneously made toward 181 color-selected IRAS sources in the outer disk of the... -
44GHz VLA obs. of methanol masers in DR21(OH)
High-mass stars play an important role in the interstellar medium, but much remains to be known about their formation. Class I methanol masers may be unique tracers of an early... -
4.7GHz OH masers in northern star formation regions
We have used the Shanghai Tianma Radio Telescope to search for three OH transitions at 4.7GHz toward 155 northern star formation regions. We detect 4.7GHz OH masers in 18 star... -
VLA 1.3 & 5cm observations of 9 EGOs in the MW
We have observed a sample of nine Extended Green Objects (EGOs) at 1.3 and 5cm with the Very Large Array (VLA) with subarcsecond resolution and ~7-14{mu}Jy/beam-sensitivities in... -
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... -
X-ray & MIR luminosities of the GBT galaxies
We present an investigation of the dependence of H_2_O maser detection rates and properties on the mid-IR active galactic nucleus (AGN) luminosity, L_AGN_, and the obscuring... -
Megamaser Cosmology Project. XI. Z74-64 VLBI obs.
As part of the survey component of the Megamaser Cosmology Project, we have discovered a disk megamaser system in the galaxy CGCG 074-064. Using the Green Bank Telescope and the... -
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.... -
Search for extraterrestrial intelligence with ATA
We report a novel radio autocorrelation search for extraterrestrial intelligence. For selected frequencies across the terrestrial microwave window (1-10GHz), observations were... -
