ALMA obs. of 70um dark high-mass clumps (ASHES)
The ALMA Survey of 70{mu}m dark High-mass clumps in Early Stages (ASHES) is designed to systematically characterize the earliest stages and constrain theories of high-mass star... -
~200 high-mass SFR plx & proper motion with VLBI
We compile and analyze approximately 200 trigonometric parallaxes and proper motions of molecular masers associated with very young high-mass stars. Most of the measurements... -
Infrared photometry of YSOs in AFGL 5157
We observationally investigate star formation process occurring in AFGL 5157 (area ~13.5pcx13.5pc) using a multi-wavelength approach. Embedded filaments are seen in the Herschel... -
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.... -
Hub-filament candidates
Star formation takes place in giant molecular clouds, resulting in mass-segregated young stellar clusters composed of Sun-like stars, brown dwarves and massive O-type... -
Complex organic molecules in high-mass SFRs
We have studied four complex organic molecules (COMs), the oxygen-bearing methyl formate (CH_3_OCHO) and dimethyl ether (CH_3_OCH_3_) as well as the nitrogen-bearing formamide...
