NGC7538 is a complex massive star-forming region. The region is composed of several radio continuum sources, one of which is IRS1, a high-mass protostar, from which a 0.3 pc molecular bipolar outflow ...
The Red MSX Source (RMS) survey has identified a sample of ~1200 massive young stellar objects (MYSOs), compact and ultra compact HII regions from a sample of ~2000 MSX and 2MASS colour selected sourc...
The collisional pumping of H_2^{16}O and H_2^{18}O masers in hot dense gas-dust clouds has been simulated numerically. New data on the rate coefficients for collisional transitions from Faure et al. (...
We report the results of a systematic survey for 95 GHz class I methanol masers towards a new sample of 192 massive young stellar object (MYSO) candidates associated with ongoing outflows (known as ex...
Electron holes are suggested to be an important source for generation of electron-cyclotron maser radiation.We demonstrate that electron holes generated in a ring-horseshoe distribution in the aurora...
We present the first detection of a 6.7 GHz Class II methanol (CH3OH) maser in the Andromeda galaxy (M31). The CH3OH maser was found in a Very Large Array (VLA) survey during the fall of 2009. We have...
Studies of 22GHz H2O maser emission from the merging galaxy NGC 6240 with double nuclei are presented. Two epochs of Very Large Array (VLA) obser-vations in the A-configuration in spectral-line mode w...
The nature of maser emission means that the apparent angular size of an individual maser spot is determined by the amplification process as well as by the instrinsic size of the emitting cloud. Highly...
We present Very Large Array observations of the 7_0-6_1 A^+ methanol maser transition at 44 GHz towards NGC 6334F, G8.67-0.36, and M17. These arcsecond resolution observations complete a previous, lar...
High resolution oh maser survey in star forming regions。
Oh maser emission toward the young planetary nebula K3-35。
A Study of the Variability of Water Maser Emission in a Sample of Young Stellar Objects。
A Study of the Variability of Water Maser Emission in a Sample of YSOS。
Evidence for Time Evolution in the Exciting Source of the Expanding Water Maser Bubble in Cepheus A。
Evidence for Time Evolution in the Exciting Source of the Expanding Water Maser Bubble in Cepheus A。
