Radiation-Driven Evolution and Gas Kinematics of the Bright-Rimmed Cloud SFO 25

Puja Porel, Archana Soam, William D. Vacca +1

Bright-rimmed clouds (BRCs) are valuable laboratories for investigating how ionizing radiation from massive stars reshapes molecular clouds and influences star formation. We presen…

Grain alignment and dust evolution physics with polarisation (GRADE-POL). II. On the physical basis of Serkowski and super-Serkowski polarisation spectra

Le Ngoc Tram, Thiem Hoang, B-G Andersson +4

Optical-to-near-infrared interstellar polarisation, induced by aligned dust grains, generally follows a convex wavelength dependence, known as the Serkowski relation. However, obse…

Evolution of starless cores in massive clumps seen by the ALMA ASHES and QUARKS surveys

Dongting Yang, Hong-li Liu, Sheng-li Qin +28

We present a systematic comparative analysis of 324 starless cores in early-phase infrared-dark clouds (IRDCs; ASHES survey) and evolved-phase infrared-bright clouds (IRBCs; QUARKS…

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…

ALMA-QUARKS view of W49N: Multipolar episodic outflow associated with the most energetic Galactic water maser

Yunfan Jiao, Tie Liu, Wenyu Jiao +28

We present a detailed investigation of a multipolar episodic molecular outflow in the mini-starburst region W49N, which hosts the most luminous water maser in the Galaxy. Using hig…

B-fields And dust in interstelLar fiLAments using Dust POLarization (BALLAD-POL): VI. Grain alignment mechanisms in the massive quiescent filament G16.96+0.27 using dust polarization observations from JCMT/POL-2

Saikhom Pravash, Thiem Hoang, Archana Soam +5

Dust polarization induced by aligned non-spherical grains acts as an important tool to trace the magnetic field (B-field) morphologies and strengths in molecular clouds and constra…
