Asymmetric Line Profiles in Dense Molecular Clumps Observed in MALT90: Evidence for Global Collapse
James M. Jackson, J. Scott Whitaker, J. M. Rathborne +6
Using molecular line data from the Millimetre Astronomy Legacy Team 90 GHz Survey (MALT90), we have searched the optically thick \hcop\, line for the "blue asymmetry" spectroscopic…
Dust spectrum and polarisation at 850 um in the massive IRDC G035.39-00.33
Mika Juvela, Vincent Guillet, Tie Liu +18
The dust sub-millimetre polarisation of star-forming clouds carries information on dust and the role of magnetic fields in cloud evolution. With observations of a dense filamentary…
The Radio Ammonia Mid-Plane Survey (RAMPS) Pilot Survey
Taylor Hogge, James Jackson, Ian Stephens +11
The Radio Ammonia Mid-Plane Survey (RAMPS) is a molecular line survey that aims to map a portion of the Galactic midplane in the first quadrant of the Galaxy (l = 10 deg - 40 deg,…
Planck Cold Clumps in the Orionis complex. II. Environmental effects on core formation
Hee-Weon Yi, Jeong-Eun Lee, Tie Liu +27
Based on the 850 m dust continuum data from SCUBA-2 at James Clerk Maxwell Telescope (JCMT), we compare overall properties of Planck Galactic Cold Clumps (PGCCs) in the Orio…
The TOP-SCOPE survey of PGCCs: PMO and SCUBA-2 observations of 64 PGCCs in the 2nd Galactic Quadrant
Chuan-Peng Zhang, Tie Liu, Jinghua Yuan +23
In order to understand the initial conditions and early evolution of star formation in a wide range of Galactic environments, we carried out an investigation of 64 \textit{Planck}…
A holistic perspective on the dynamics of G035.39-00.33: the interplay between gas and magnetic fields
Tie Liu, Pak Shing Li, Mika Juvela +54
Magnetic field is one of the key agents that play a crucial role in shaping molecular clouds and regulating star formation, yet the complete information on the magnetic field is no…
Filamentary Fragmentation and Accretion in High-Mass Star-Forming Molecular Clouds
Xing Lu, Qizhou Zhang, Hauyu Baobab Liu +7
Filamentary structures are ubiquitous in high-mass star-forming molecular clouds. Their relation with high-mass star formation is still to be understood. Here we report interferome…
