Protonated hydrogen cyanide as a tracer of pristine molecular gas
Y. Gong, F. J. Du, C. Henkel +11
Protonated hydrogen cyanide, HCNH, plays a fundamental role in astrochemistry because it is an intermediary in gas-phase ion-neutral reactions within cold molecular clouds. H…
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…
Discovery of non-metastable ammonia masers in Sagittarius B2
Y. T. Yan, C. Henkel, K. M. Menten +10
We report the discovery of widespread maser emission in non-metastable inversion transitions of NH toward various parts of the Sagittarius B2 molecular cloud/star forming regio…
Deuterated molecules in regions of high-mass star formation
Igor I. Zinchenko, Andrey G. Pazukhin, Elena A. Trofimova +3
We present the results of our studies of deuterated molecules (DCN, DNC, DCO, ND and NHD) in regions of high-mass star formation, which include a survey of such reg…
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…
Energizing Star Formation: The Cosmic Ray Ionization Rate in NGC 253 Derived From ALCHEMI Measurements of HO and SO
Jonathan Holdship, Jeffrey G. Mangum, Serena Viti +16
The cosmic ray ionization rate (CRIR) is a key parameter in understanding the physical and chemical processes in the interstellar medium. Cosmic rays are a significant source of en…
