Water masers associated with IR dark cloud cores
We present a survey of the 6_16_-5_23_ H_2_O maser transition toward a sample of 140 compact cores in infrared dark clouds using the Very Large Array. Strong (>1Jy) H_2_O... -
W49N H2O maser outflow: distance and kinematics
Study of the motions of 105 H2O maser features clustered around a newly formed star in W49N yields the kinematics of the gas flow, the distance to the source, and the spatial... -
SiO maser emission in evolved stars
We aim to study the time evolution of the SiO maser lines in Mira-type and semi-regular variables at short timescales. We observed the SiO maser lines at 7mm and 3mm using the... -
OH 6035MHz line in high-mass SFRs
The excited states of OH masers detected in the environment of high-mass young stellar objects (HMYSOs) are important for improving our understanding of the physical conditions... -
Massive star-forming regions radio lines
We present Australia Telescope Compact Array (ATCA) observations of the H_2_O maser line and radio continuum at 18.0GHz and 22.8GHz toward a sample of 192 massive star-forming... -
OH masers towards high mass protostellar object
Masers are important tracers of the early evolution of young high mass stars, but the relationship between different types of maser and the evolutionary state of the exciting... -
Rest frequencies of methanol maser lines
We report accurate laboratory measurements of selected methanol transition frequencies between 0.834 and 230GHz in order to facilitate astronomical velocity analyses. New data...
