Dense Molecular Clumps with Large Blue Asymmetries: Evidence for Collapse
James M. Jackson, J. Scott Whitaker, Edward Chambers +10
An analysis of the Millimetre Astronomy Legacy Team 90 GHz (MALT90) survey has produced a sample of 27 candidate dense molecular clumps with large collapse motions, as revealed by…
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,…
Synthetic Spectral Signatures from Isothermal Collapsing Gas and the Interpretation of Infall Profiles
Robert M. Loughnane, Enrique Vázquez-Semadeni, Raúl Naranjo-Romero
We revisit the interpretation of blue-excess molecular lines from dense collapsing cores, considering recent numerical results that suggest prestellar core collapse occurs from the…
Thermal Feedback in the high-mass star and cluster forming region W51
Adam Ginsburg, Ciriaco Goddi, J. M. Diederik Kruijssen +11
High-mass stars have generally been assumed to accrete most of their mass while already contracted onto the main sequence, but this hypothesis has not been observationally tested.…
Hierarchical gravitational fragmentation. I. Collapsing cores within collapsing clouds
Raúl Naranjo-Romero, Enrique Vázquez-Semadeni, Robert M. Loughnane
We investigate the Hierarchical Gravitational Fragmentation scenario through numerical simulations of the prestellar stages of the collapse of a marginally gravitationally unstable…
Observation of HCN hyperfine line anomalies towards low- and high-mass star-forming cores
R. M. Loughnane, M. P. Redman, M. A. Thompson +3
HCN is becoming a popular choice of molecule for studying star formation in both low- and high-mass regions and for other astrophysical sources from comets to high-redshift galaxie…
Supersonic turbulence in the cold massive core JCMT 18354-0649S
P. B. Carolan, T. Khanzadyan, M. P. Redman +6
An example of a cold massive core, JCMT 18354-0649S, a possible high mass analogue to a low mass star forming core is studied. Line and continuum observations from JCMT, Mopra Tele…
