Anomalously high deuterium fractionation in a galactic translucent cloud: a challenge to chemical models
Gan Luo, Zhi-Yu Zhang, Thomas G. Bisbas +8
Deuterated (D-) species have long been proposed to diagnose the physical conditions and chemical evolution of cold dense molecular clouds. While deuterium fractionation has been ex…
Tight correlation of star formation with [Ci] and CO lines across cosmic time
Theodoros Topkaras, Thomas G. Bisbas, Zhi-Yu Zhang +1
Context. Cold molecular gas tracers, such as CI and CO lines, have been widely used to infer specific characteristics of the ISM and to derive star-formation relations among galaxi…
Metallicity dependence of the CO-to-H and the [CI]-to-H conversion factors in galaxies
Thomas G. Bisbas, Zhi-Yu Zhang, Maria-Christina Kyrmanidou +6
Understanding the molecular gas content in the interstellar medium (ISM) is crucial for studying star formation and galaxy evolution. The CO-to-H () and the [CI]-to…
Inadequate turbulent support in low-metallicity molecular clouds
Lingrui Lin, Zhi-Yu Zhang, Junzhi Wang +16
The dynamic properties of molecular clouds are set by the interplay of their self-gravity, turbulence, external pressure and magnetic fields. Extended surveys of Galactic molecular…
