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…
Discovery of a radio jet in the Cloverleaf Quasar at z = 2.56
Lei Zhang, Zhi-Yu Zhang, James. W. Nightingale +10
The fast growth of supermassive black holes and their feedback to the host galaxies play an important role in regulating the evolution of galaxies, especially in the early Universe…
Scientific Objectives of the Xue-shan-mu-chang 15-meter Submillimeter Telescope
XSMT Project Collaboration Group, Yiping Ao, Jin Chang +48
Submillimeter astronomy is poised to revolutionize our understanding of the Universe by revealing cosmic phenomena hidden from optical and near-infrared observations, particularly…
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…
