論文摘要

On the fragmentation in dense cores

[ Poster ]

Ya-Wen Tang (ASIAA)

Our recent analysis of the G34 IRDC (Tang et al. 2019) reports a significantly different relative importance between the gravity, magnetic field and turbulence for three cores that show clearly different fragmentation structures. With the ongoing ALMA large program ALMAGAL, we will observe 1000 cores with both 3" and 0.2" angular resolution. In this talk, I will report the status of ALMAGAL and the science goal which we will lead: "the correlation between the magnetic field at filament scale orientation and the distribution (including fragmentation level) of cores."
