From inter-filamentary gas to filaments and hubs: gas flows in the Mon R2 hub-filament system
Jihye Hwang, Doris Arzoumanian, Yoshito Shimajiri +5
Hub-filament systems (HFSs) play an important role in the formation of massive stars and star clusters. Although the velocity structures along dense filaments have been studied, th…
Probing the ion-neutral drift velocity towards the L1544 prestellar core: Detection of ambipolar diffusion using ND and para-NHD
Doris Arzoumanian, Silvia Spezzano, Tommaso Grassi +9
The dynamical role of the magnetic field in the star formation process is tightly linked to the coupling between matter and the field. This coupling is due to the interaction betwe…
BISTRO Survey: Gravity-Dominated and Magnetically Regulated Star Formation in M17 SW
Mengke Zhao, Keping Qiu, Ji-hyun Kang +27
We present high-resolution magnetic field maps of the M17 SW molecular cloud using JCMT 850 m dust polarization at a scale of 14. The magnetic field exhibits a distinct arc…
Ion-Neutral Drift Velocity as a Diagnostic of Dust Growth and Magnetic Field in Star-Forming Environments
Haruka Fukihara, Yusuke Tsukamoto, Hiroyuki Hirashita +2
Recent observations have revealed that the ion-neutral drift velocity in star-forming molecular clouds and dense cores is on the order of 100 m s^-1. Theoretical studies have shown…
Fragmenting Filaments and Evolving Cores -- Insights from Dust Polarisation Study of a filament in Northern Orion B
Kshitiz K. Mallick, Doris Arzoumanian, Satoko Takahashi +5
We present an analysis of polarised dust emission at 850 micron for a parsec long filament in the northern part of the Orion B molecular cloud. The region was observed by the JCMT…
FIRESTORM I: Stellar Feedback and Gas Kinematics in the Evolved W40 Hub-Filament System
Ming-Kang Lim, Ram K. Yadav, L. K. Dewangan +12
The FIRESTORM project--Feedback-Induced Regions and Emission from Star-forming Tracers of ObseRvable Molecular Gas--has targeted four star-forming regions to quantify the impact of…
