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…
Gas dynamics in an AGN-host galaxy at : regular rotation, non-circular motions, and mass models
Lingrui Lin, Federico Lelli, Carlos De Breuck +9
The gas dynamics of galaxies provide critical insights into the evolution of both baryons and dark matter (DM) across cosmic time. In this context, galaxies at cosmic noon -- the p…
Molecular gas mass measurements of an active, starburst galaxy at using ALMA observations of the [CI], CO and dust emission
Hao-Tse Huang, Allison W. S. Man, Federico Lelli +7
We present new ALMA observations of a starburst galaxy at cosmic noon hosting a radio-loud active galactic nucleus: PKS 0529-549 at . To investigate the conditions of its c…
Ionized Carbon in Galaxies: The [C II] 158 m Line as a Total Molecular Gas Mass Tracer Revisited
Yinghe Zhao, Jiamin Liu, Zhi-Yu Zhang +1
In this paper we present a statistical study of the [C II] 158 m line and the CO(1-0) emission for a sample of 200 local and high- (32 sources with ) galaxies with…
The CO-dark molecular gas in the cold HI arc
Gan Luo, Di Li, Zhi-yu Zhang +6
The CO-dark molecular gas (DMG), which refers to the molecular gas not traced by CO emission, is crucial for the evolution of the interstellar medium (ISM). While the gas propertie…
-enhanced Astrochemistry: the Carbon cycle in extreme galactic conditions
Thomas G. Bisbas, Zhi-Yu Zhang, Eda Gjergo +8
Astrochemistry has been widely developed as a power tool to probe physical properties of the interstellar medium (ISM) in various conditions of the Milky Way (MW) Galaxy, and in ne…
An improved method to measure and abundance ratios: revisiting CN isotopologues in the Galactic outer disk
Yichen Sun, Zhi-Yu Zhang, Junzhi Wang +7
The variations of elemental abundance and their ratios along the Galactocentric radius result from the chemical evolution of the Milky Way disks. The ratio in p…
