Kirk, Helen, Johnstone, Doug, Basu, Shantanu
We analyze a suite of thin sheet magnetohydrodynamical simulations based on the formulation of Basu, Ciolek, Dapp & Wurster. These simulations allow us to examine the observational consequences to a...

Abstract. The Perseus molecular cloud and its surroundings contain several regions of active or recent star formation lying within about 300 pc of the Sun (see Figure 1). Roughly a dozen OB and over...
Jorgensen, Jes, Johnstone, Doug, Kirk, Helen, Myers, Philip, Allen, Lori, Shirley, Yancy
We present a census of the population of deeply embedded young stellar objects (YSOs) in the Ophiuchus molecular cloud complex based on a combination of Spitzer Space Telescope mid-infrared data from...
The SCUBA Legacy Catalogue: Continuum Objects Detected by SCUBA (2008)
Di Francesco, James, Johnstone, Doug, Kirk, Helen, MacKenzie, Todd, Ledwosinska, Elizabeth
We present the SCUBA Legacy Catalogues, two comprehensive sets of continuum maps (and catalogues) using data at 850 microns and 450 microns of the various astronomical objects obtained with the...
Dynamics of Dense Cores in the Perseus Molecular Cloud (2007)
Kirk, Helen, Johnstone, Doug, Tafalla, Mario
We survey the kinematics of over one hundred and fifty candidate (and potentially star-forming) dense cores in the Perseus molecular cloud with pointed N2H+(1-0) and simultaneous C18O(2-1)...
Jorgensen, Jes K., Johnstone, Doug, Kirk, Helen, Myers, Philip C.
We present a census of the population of deeply embedded young stellar objects (YSOs) in the Perseus molecular cloud complex based on a combination of Spitzer Space Telescope mid-IR data from the c2d...
The complete survey of star-forming regions: Phase I data (2006)
Ridge, Naomi A., Di Francesco, James, Kirk, Helen, Li, Di, Goodman, Alyssa A., Alves, João F., ...
We present an overview of data available for the Ophiuchus and Perseus molecular clouds from Phase I of the COMPLETE Survey of Star-Forming Regions. This survey provides a range of data complementary...
The COMPLETE Survey of Star-Forming Regions: Phase I Data (2006)
Ridge, Naomi A., Di Francesco, James, Kirk, Helen, Li, Di, Goodman, Alyssa A., Alves, João F., ...
We present an overview of data available for the Ophiuchus and Perseus molecular clouds from ``Phase I'' of the COMPLETE Survey of Star-Forming Regions. This survey provides a range of data...
The Large and Small Scale Structures of Dust in the Star-Forming Perseus Molecular Cloud (2006)
Kirk, Helen, Johnstone, Doug, Di Francesco, James
We present an analysis of ~3.5 square degrees of submillimetre continuum and extinction data of the Perseus molecular cloud. We identify 58 clumps in the submillimetre map and we identify 39...
An Extinction Threshold for Protostellar Cores in Ophiuchus (2004)
Johnstone, Doug, Di Francesco, James, Kirk, Helen
We have observed continuum emission at lambda = 850 microns over ~4 square degrees of the Ophiuchus star-forming cloud using SCUBA on the JCMT, producing a submillimetre continuum map twenty times...
