Density Functional Theory Calculations on the Interstellar Formation of Biomolecules
Qingli Liao, Junzhi Wang, Peng Xie +2
The density functional theory (DFT) is the most versatile electronic structure method used in quantum chemical calculations, and is increasingly applied in astrochemical research.…
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…
The HI Gas Disk Thickness of the Ultra-diffuse Galaxy AGC 242019
Xin Li, Yong Shi, Zhi-Yu Zhang +5
Ultra-diffuse galaxies (UDGs) are as faint as dwarf galaxies but whose sizes are similar to those of spiral galaxies. A variety of formation mechanisms have been proposed, some of…
Properties of dense molecular gas along the major axis of M 82
Fei Li, Zhi-Yu Zhang, Junzhi Wang +6
Dense gas is important for galaxy evolution and star formation. Optically-thin dense-gas tracers, such as isotopologues of HCN, HCO+, etc., are very helpful to diagnose excitation…
Dense Gas and Star Formation in Nearby Infrared Bright Galaxies: APEX survey of HCN and HCO+ J=2-1
Jing Zhou, Zhi-Yu Zhang, Yu Gao +6
Both Galactic and extragalactic studies on star formation suggest that stars form directly from dense molecular gas. To trace such high volume density gas, HCN and HCO+ J=1-0 have…
HC3N Observations of Nearby Galaxies
Xue-Jian Jiang, Jun-Zhi Wang, Yu Gao +1
Aims. We aim to systematically study the properties of the different transitions of the dense molecular gas tracer HC3N in galaxies. Methods. We have conducted single-dish observat…
