Direct measurements of carbon and sulfur isotope ratios in the Milky Way
Y. T. Yan, C. Henkel, C. Kobayashi +7
With the IRAM 30 meter telescope, we performed observations of the = 2-1 transitions of CS, CS, CS, CS, CS, CS, and CS a…
Interstellar Nitrogen Isotope Ratios: New NH3 Data from the Galactic Center out to the Perseus Arm
J. L. Chen, J. S. Zhang, C. Henkel +10
Our aim is to measure the interstellar 14N/15N ratio across the Galaxy, to establish a standard data set on interstellar ammonia isotope ratios, and to provide new constraints on t…
Cyanopolyyne line survey towards high-mass star-forming regions with TMRT
Y. X. Wang, J. S. Zhang, Y. T. Yan +8
We carried out a cyanopolyyne line survey towards a large sample of HMSFRs using the Shanghai Tian Ma 65m Radio Telescope (TMRT). Our sample consisted of 123 targets taken from the…
Discovery of ammonia (9,6) masers in two high-mass star-forming regions
Y. T. Yan, C. Henkel, K. M. Menten +8
Molecular maser lines are signposts of high-mass star formation, probing excitation and kinematics of very compact regions in the close environment of young stellar objects and pro…
