The dense ring in the Coalsack: the merging of two subsonic flows
J. M. Rathborne, C. J. Lada, W. Walsh +2
A recent high angular resolution extinction map toward the most opaque molecular globule, Globule 2, in the Coalsack Nebula revealed that it contains a strong central ring of dust…
An Unbiased Survey of 500 Nearby Stars for Debris Disks: A JCMT Legacy Program
B. C. Matthews, J. S. Greaves, W. S. Holland +28
We present the scientific motivation and observing plan for an upcoming detection survey for debris disks using the James Clerk Maxwell Telescope. The SCUBA-2 Unbiased Nearby Stars…
The James Clerk Maxwell Telescope Legacy Survey of Nearby Star-forming Regions in the Gould Belt
D. Ward-Thompson, J. Di Francesco, J. Hatchell +59
This paper describes a James Clerk Maxwell Telescope (JCMT) legacy survey that has been awarded roughly 500 hrs of observing time to be carried out from 2007 to 2009. In this surve…
The SCUBA-2 "All-Sky" Survey
M. A. Thompson, S. Serjeant, T. Jenness +45
The sub-millimetre wavelength regime is perhaps the most poorly explored over large areas of the sky, despite the considerable effort that has been expended in making deep maps ove…
Observations of chemical differentiation in clumpy molecular clouds
J. V. Buckle, S. D. Rodgers, E. S. Wirström +4
We have extensively mapped a sample of dense molecular clouds (L1512, TMC-1C, L1262, Per 7, L1389, L1251E) in lines of HC3N, CH3OH, SO and C^{18}O. We demonstrate that a high degre…
The JCMT Spectral Legacy Survey
R. Plume, G. A. Fuller, F. Helmich +30
Stars form in the densest, coldest, most quiescent regions of molecular clouds. Molecules provide the only probes which can reveal the dynamics, physics, chemistry and evolution of…
A sensitive submillimetre survey of Broad Absorption Line quasars
R. S. Priddey, S. C. Gallagher, K. G. Isaak +3
Using the SCUBA bolometer array on the JCMT, we have carried out a submillimetre survey of Broad Absorption Line quasars (BALQs). The sample has been chosen to match, in redshift a…
Star Formation in the Northern Cloud Complex of NGC 2264
Abigail S. Hedden, Christopher K. Walker, Christopher E. Groppi +1
We have made continuum and spectral line observations of several outflow sources in the Mon OB1 dark cloud (NGC 2264) using the Heinrich Hertz Telescope (HHT) and ARO 12m millimete…
Chemical Processes in Cometary Comae
S. B. Charnley, S. D. Rodgers, H. M. Butner +1
Recent developments in the chemical modelling of cometary comae are described. We discuss the cyanide chemistry and present new HCN observations of the recent comet C/2002 C1 (Ikey…
Detection of Infall Signatures Towards Serpens SMM4
G. Narayanan, G. Moriarty-Schieven, C. K. Walker +1
We present the detection of kinematic infall signatures towards the Class 0 protostellar system SMM4 in the Serpens cloud core. We have observed the dense molecular gas towards the…
Wide-Field Thermal Imaging of the Orion Nebula at High Spatial Resolution
L. K. Deutsch, M. Kassis, N. Smith +5
We describe multi-wavelength (8--20 micron), diffraction-limited, mid-infrared images of the OMC-1 cloud core in Orion, covering an approximately two arcminute area around the Trap…
L1551NE - Discovery of a Binary Companion
G. H. Moriarty-Schieven, J. A. Powers, H. M. Butner +2
L1551NE is a very young (class 0 or I) low-mass protostar located close to the well-studied L1551 IRS5. We present here evidence, from 1.3mm continuum interferometric observations…
A Sub-millimeterwave ``Flare'' from GG Tau?
Gerald H. Moriarty-Schieven, Harold M. Butner
We have monitored the millimeter and submillimeter emission from the young stellar object GG Tau, a T Tauri binary system surrounded by a massive circumbinary disk. We find that be…
