The ALMA Survey of Star Formation and Evolution in Massive Protoclusters with Blue Profiles (ASSEMBLE) aims to investigate the process of mass assembly and its connection to high-m…
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…

Feng-Wei Xu, Ke Wang, Tie Liu +37
We present ALMA Band-3/7 observations towards "the Heart" of a massive hub-filament system (HFS) SDC335, to investigate its fragmentation and accretion. At a resolution of $\sim0.0…
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…
LAMOST meets Gaia: The Galactic Open Clusters
Xiaoting Fu, Angela Bragaglia, Chao Liu +14
Open Clusters are born and evolve along the Milky Way plane, on them is imprinted the history of the Galactic disc, including the chemical and dynamical evolution. Chemical and dyn…
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…
A Low-mass Cold and Quiescent Core Population in a Massive Star Protocluster
Shanghuo Li, Xing Lu, Qizhou Zhang +24
Pre-stellar cores represent the initial conditions of star formation. Although these initial conditions in nearby low-mass star-forming regions have been investigated in detail, su…
