Tails of Gravity: Persistence of Star Formation in the CMZ Environment
Linjing Feng, Sihan Jiao, Fengwei Xu +16
We characterize star-forming gas in six molecular clouds (Sgr B1-off, Sgr B2, Sgr C, the 20 km s and 50 km s molecular clouds, and the Brick) in the Galactic central…
Deep Andromeda JCMT-SCUBA2 Observations. The Submillimeter Maps and Giant Molecular Clouds
Sihan Jiao, Jingwen Wu, Hauyu Baobab Liu +23
We have carried out unprecedentedly deep, nearly confusion-limited JCMT-SCUBA2 mapping observations on the nearest spiral galaxy, M31 (Andromeda). The 850 m image with a 5…
An S-shaped filament formed due to Cloud-Cloud Collision in molecular cloud G178.28-00.61
Tianwei Zhang, Tie Liu, Yuefang Wu +18
We present compelling observational evidence supporting G178.28-00.61 as an early-stage candidate for Cloud-Cloud Collision (CCC), with indications of the formation of an S-shaped…
Why is the Star Formation Rate Proportional to Dense Gas Mass?
Sihan Jiao, Fengwei Xu, Hauyu Baobab Liu +14
One of the most profound empirical laws of star formation is the Gao-Solomon relation, a linear correlation between the star formation rate (SFR) and the dense molecular gas mass.…
Gravitationally Bound Gas Determines Star Formation in the Galaxy
Sihan Jiao, Jingwen Wu, Zhi-Yu Zhang +13
Stars form from molecular gas under complex conditions influenced by multiple competing physical mechanisms, such as gravity, turbulence, and magnetic fields. However, accurately i…
CRAFTS for HI cosmology: I. data processing pipeline and validation tests
Wenxiu Yang, Laura Wolz, Yichao Li +20
We present the calibration procedures and validation of source measurement with the data of the Commensal Radio Astronomy FAST Survey (CRAFTS) for \HI intensity mapping by the Five…
