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…

A comprehensive catalogue of OB cluster candidates in M31 and their association with giant molecular clouds

Yuan Liang, Guang-Wei Li, Chao-Wei Tsai +1

We present a new catalogue of 578 OB cluster (OBC) candidates in the Andromeda galaxy (M31), identified using a MeanShift-based algorithm on HST's F275W-band imaging from the PHAT…

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…

The HASHTAG project II. Giant molecular cloud properties across the M31 disc

Yikai Deng, Zongnan Li, Zhiyuan Li +17

We present a study of giant molecular cloud (GMC) properties in the Andromeda galaxy (M31) using CO(3-2) data from the James Clerk Maxwell Telescope (JCMT) in selected regions acro…

Ring or no ring -- Revisiting the Multiphase Nuclear Environment in M31

Zongnan Li, Zhao Su, Sumin Wang +9

Nuclear rings, prevalent in barred galaxies, are essential to understanding gas transport toward galactic nuclei. However, the peculiar nuclear ring in our neighboring galaxy M31 r…

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…
