    • A cluster in the making: ALMA reveals the initial conditions for high-mass cluster formation 

      Rathborne, Jill; Longmore, S. N.; Jackson, J. M.; Alves, J. F.; Bally, J.; Bastian, N.; Contreras, Y.; Foster, J. B.; Garay Brignardello, Guido; Kruijssen, J. M.; Testi, L.; Walsh, A. J. (IOP PUBLISHING LTD, 2015)
      G0.253+0.016 is a molecular clump that appears to be on the verge of forming a high-mass cluster: its extremely low dust temperature, high mass, and high density, combined with its lack of prevalent star formation, make ...

      G0.253+0.016 is a molecular clump that appears to be on the verge of forming a high-mass cluster: its extremely low dust temperature, high mass, and high density, combined with its lack of prevalent star formation, make ...
    • THE EARLY STAGES OF STAR FORMATION IN INFRARED DARK CLOUDS: CHARACTERIZING THE CORE DUST PROPERTIES 

      Rathborne, Jill; Jackson, J. M.; Chambers, E. T.; Stojimirovic, I.; Simon, R.; Shipman, R.; Frieswijk, W. (The American Astronomical Society, 2010-05-20)
      Identified as extinction features against the bright Galactic mid-infrared background, infrared dark clouds (IRDCs) are thought to harbor the very earliest stages of star and cluster formation. In order to better characterize ...
    • Far-Infrared Dust Temperatures and Column Densities of the MALT90 Molecular Clump Sample 

      Guzmán, Andrés E.; Sanhueza, Patricio; Contreras, Yanett; Smith, Howard A.; Jackson, James M.; Hoq, Sadia; Rathborne, Jill (IOP Publishing, 2015)
      We present dust column densities and dust temperatures for similar to 3000 young, high-mass molecular clumps from the Millimeter Astronomy Legacy Team 90 GHz survey, derived from adjusting single-temperature dust emission ...
    • Fragmentation in filamentary molecular clouds 

      Contreras, Yanett; Garay Brignardello, Guido; Rathborne, Jill; Sanhueza, Patricio (OXFORD UNIV PRESS, 2016)
      Recent surveys of dust continuum emission at sub-mm wavelengths have shown that filamentary molecular clouds are ubiquitous along the Galactic plane. These structures are inhomogeneous, with overdensities that are sometimes ...
    • G0.253+0.016: A centrally condensed, high-mass protocluster. 

      Rathborne, Jill; Longmore, S. N.; Jackson, J. M.; Foster, J. B.; Contreras, Y.; Garay Brignardello, Guido; Testi, L.; Alves, J. F.; Bally, J.; Bastian, N.; Kruijssen, J. M. D.; Bressert, E. (The American Astronomical Society., 2014-04-25)
      Despite their importance as stellar nurseries and the building blocks of galaxies, very little is known about the formation of the highest mass clusters. The dense clump G0.253+0.016 represents an example of a clump that ...
    • A hot molecular outflow driven by the ionized jet associated with IRAS 16562-3959 

      Guzmán, Andrés; Garay Brignardello, Guido; Brooks, Kate J.; Rathborne, Jill; Güsten, Rolf (The American Astronomical Society, 2011-08-01)
      We report molecular line observations in the CO J = 3→2, 6→5, and 7→6 transitions, made using the Atacama Pathfinder Experiment Telescope, toward the massive and dense core IRAS 16562−3959. This core harbors a string of ...
    • Infall signatures in a prestellar core embedded in the high-mass 70 mu m Dark IRDC G331.372-00.116 

      Contreras, Yanett; Sanhueza, Patricio; Jackson, James M.; Guzmán, Andrés E.; Longmore, Steven; Garay Brignardello, Guido; Zhang, Qizhou; Quang, Nguyen-Lu'o'Ng; Tatematsu, Ken'ichi; Nakamura, Fumitaka; Sakai, Takeshi; Ohashi, Satoshi; Liu, Tie; Saito, Masao; Gómez, Laura; Rathborne, Jill; Whitaker, Scott (IOP Publishing, 2018-07)
      Using Galactic Plane surveys, we have selected a massive (1200M circle dot), cold (14 K) 3.6-70 mu m dark IRDC, G331.372-00.116. This infrared dark cloud (IRDC) has the potential to form high-mass stars, and given the ...
    • Linking dense gas from the milky way to external galaxies 

      Stephens, Ian W.; Jackson, James M.; Whitaker, J. Scott; Contreras, Yanett; Guzmán, Andres E.; Sanhueza, Patricio; Foster, Jonathan B.; Rathborne, Jill (IOP Publishing, 2016-06-10)
      In a survey of 65 galaxies, Gao & Solomon found a tight linear relation between the infrared luminosity (L-IR, a proxy for the star formation rate) and the HCN(1-0) luminosity (L-HCN). Wu et al. found that this relation ...
    • Molecular Line Emission Towards High-Mass Clumps: The MALT90 Catalogue 

      Rathborne, Jill; Whitaker, John; Jackson, J. M.; Foster, J. B.; Contreras, Y.; Stephens, I. W.; Guzmán Fernández, Andrés; Longmore, S. N.; Sanhueza, P.; Schuller, F.; Wyrowski, Friedrich; Urquhart, J. S. (Cambridge University Press, 2016)
      The Millimetre Astronomy Legacy Team 90 GHz survey aims to characterise the physical and chemical evolution of high-mass clumps. Recently completed, it mapped 90 GHz line emission towards 3 246 high-mass clumps identified ...
    • The Red MSX Source survey: distribution and properties of a sample of massive young stars 

      Urquhart, J. S.; Moore, T. J. T.; Hoare, M. G.; Lumsden, S. L.; Oudmaijer, R. D.; Rathborne, Jill; Mottram, J. C.; Davies, B.; Stead, J. J. (2011)
      The Red MSX Source (RMS) survey has identified a large sample of massive young stellar objects and ultra compact HII regions from a sample of ∼2000 MSX and Two Micron All Sky Survey (2MASS) colour selected sources. Using ...
