    • A census of molecular hydrogen outflows and their sources along the orion a molecular ridge 

      Davis, C. J.; Froebrich, D.; Stanke, T.; Megeath, S. T.; Kumar, M. S. N.; Adamson, A.; Eislöffel, J.; Gredel, R.; Khanzadyan, T.; Lucas, P.; Smith, M. D.; Varricatt, W. P. (EDP Sciences, 2009-01-14)
      Aims. A census of molecular hydrogen flows across the entire Orion A giant molecular cloud is sought. With this paper we aim to associate each flow with its progenitor and associated molecular core, so that the characteristics ...

    • Champagne flutes and brandy snifters: modelling protostellar outflow-cloud chemical interfaces 

      Rollins, R. P.; Rawlings, J. M. C.; Williams, D. A.; Redman, M. P. (Oxford University Press (OUP), 2014-08-06)
      A rich variety of molecular species has now been observed towards hot cores in star-forming regions and in the interstellar medium. An increasing body of evidence from millimetre interferometers suggests that many of these ...

    • Gm 2-4: a signpost for low- and intermediate-mass star formation★ 

      Khanzadyan, Tigran; Movsessian, Tigran A.; Davis, Chris J.; Magakian, Tigran Yu.; Gredel, Roland; Nikogossian, Elena H. (Oxford University Press (OUP), 2011-11-08)
      We present a multi-wavelength study of the region towards the GM 2-4 nebula and the nearby source IRAS 05373+2340. Our near-infrared H2 10 S(1) line observations reveal various shock-excited features which are part of ...

    • Observations of hcn hyperfine line anomalies towards low- and high-mass star-forming cores 

      Loughnane, R. M.; Redman, M. P.; Thompson, M. A.; Lo, N.; O’Dwyer, B.; Cunningham, M. R. (Oxford University Press (OUP), 2011-12-08)
      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 galaxies. However, a major and often overlooked ...

    • Supersonic turbulence in the cold massive core jcmt 18354���0649s��� 

      Carolan, P. B.; Khanzadyan, T.; Redman, M. P.; Thompson, M. A.; Jones, P. A.; Cunningham, M. R.; Loughnane, R. M.; Bains, I.; Keto, E. (Oxford University Press (OUP), 2009-11-21)
      An example of a cold massive core, JCMT 18354-0649S which is a possible high-mass analogue to a low-mass star-forming core, is studied. Line and continuum observations from James Clerk Maxwell Telescope, Mopra Telescope ...

    • Unified models of molecular emission from class 0 protostellar outflow sources 

      Rawlings, J. M. C.; Redman, M. P.; Carolan, P. B. (Oxford University Press (OUP), 2013-08-20)
      Low-mass star-forming regions are more complex than the simple spherically symmetric approximation that is often assumed. We apply a more realistic infall/outflow physical model to molecular/continuum observations of three ...
