MIAO-ALMA: Shocks and Protostellar Outflows in 70 m-dark clumps with 1 /
Shuting Lin, Siyi Feng, Junzhi Wang +16
To investigate the initial conditions of high-mass star-forming regions, we use SiO (2-1) emission to trace early shock-related kinematics toward sixteen 70 m-dark and massive c…
Spatially resolved thermal dust emission in the L1157 outflow reveals grain-driven molecular enrichment
Siyi Feng, Hauyu Baobab Liu, Yang Lu +11
Protostellar outflow shocks reshape local dust properties and molecular chemistry. The L1157 outflow is an archetypal chemically rich shocked region, but the thermal dust associate…
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…
The MALATANG survey: star formation, dense gas, and AGN feedback in NGC 1068
Shuting Lin, Siyi Feng, Zhi-Yu Zhang +14
We aim to investigate the interplay between dense molecular gas, star formation, and active galactic nucleus (AGN) feedback in the luminous infrared galaxy (LIRG) NGC 1068 at sub-k…
Dense Molecular Ring-like structure in gaseous CO depletion region G34.74-0.12
Shuting Lin, Siyi Feng, Fengwei Xu +14
We report the discovery of a dense molecular ring-like structure in a dense (10 cm), cold (pc-scale CO depletion at a factor of 5), and young (10 year) star-forming…
Subclustering and Star Formation Efficiency in Three Protoclusters in the Central Molecular Zone
Suinan Zhang, Xing Lu, Adam Ginsburg +21
We present so far the highest resolution (0.04") ALMA 1.3 mm continuum observations of three massive star-forming clumps in the Central Molecular Zone, namely 20 km s…
