Abundance ratios of OH/CO and HCO+/CO as probes of the cosmic ray ionization rate in diffuse clouds
Gan Luo, Zhiyu Zhang, Thomas G. Bisbas +6
The cosmic-ray ionization rate (CRIR, ) is one of the key parameters controlling the formation and destruction of various molecules in molecular clouds. However, the current m…
Dependence of Chemical Abundance on the Cosmic Ray Ionization Rate in IC 348
Gan Luo, Zhi-Yu Zhang, Thomas G. Bisbas +8
Ions (e.g., H, HO) have been used extensively to quantify the cosmic-ray ionization rate (CRIR) in diffuse sightlines. However, measurements of CRIR in low-to-interme…
The role of neutral hydrogen in setting the abundances of molecular species in the Milky Way's diffuse interstellar medium. II. Comparison between observations and theoretical models
Daniel R. Rybarczyk, Munan Gong, Snezana Stanimirovic +6
We compare observations of HI from the Very Large Array (VLA) and the Arecibo Observatory and observations of HCO from the Atacama Large Millimeter/submillimeter Array (ALMA) a…
Precise Measurements of CH Maser Emission and Its Abundance in Translucent Clouds
Ningyu Tang, Di Li, Gan Luo +5
We present high-sensitivity CH 9 cm ON/OFF observations toward 18 extra-galactic continuum sources that have been detected with OH 18 cm absorption in the Millennium survey with th…
The role of neutral hydrogen in setting the abundances of molecular species in the Milky Way's diffuse interstellar medium. I. Observational constraints from ALMA and NOEMA
Daniel R. Rybarczyk, Snezana Stanimirovic, Munan Gong +7
We have complemented existing observations of HI absorption with new observations of HCO, CH, HCN, and HNC absorption from the Atacama Large Millimeter/submillimeter Array…
Convergent Filaments Contracting Towards an Intermediate-mass Prestellar Core
Zhiyuan Ren, Lei Zhu, Hui Shi +11
Filamentary structures are closely associated with star-forming cores, but their detailed physical connections are still not clear. We studied the dense gas in the region of OMC-3…
