A complete survey of filaments in Cygnus X
Yingxi Li, Keping Qiu
Filamentary structures are widely observed in molecular clouds, yet most filament observations are biased toward case studies and small samples; a uniform census within a single gi…
Unveiling Fiber Networks and Core Formation in the DR21 South Filament
Kai Yang, Keping Qiu, Xing Pan
We present high-resolution (1000 AU) 3 mm observations with the NOrthern Extended Millimeter Array toward the DR21 South Filament, aiming to reveal its internal fragmentation…
Surveys of clumps, cores, and condensations in Cygnus-X: Searching for Keplerian disks on the scale of 500 au
Xing Pan, Keping Qiu, Qizhou Zhang
Over the past decades, observational evidence of circumstellar disks around massive protostars has been steadily accumulating. However, there have also been cases of non-detections…
ALMA observations of massive clouds in the central molecular zone: slim filaments tracing parsec-scale shocks
Kai Yang, Xing Lu, Yichen Zhang +22
The central molecular zone (CMZ) of our Galaxy exhibits widespread emission from SiO and various complex organic molecules (COMs), yet the exact origin of such emission is uncertai…
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…
