  • A Herschel view of the far-infrared properties of submillimetre galaxies 

    Magnelli, B., D. Lutz, P. Santini, A. Saintonge, et al. 2012. "A Herschel view of the far-infrared properties of submillimetre galaxies." Astronomy and astrophysics 539:155.
    We study a sample of 61 submillimetre galaxies (SMGs) selected from ground-based surveys, with known spectroscopic redshifts and observed with Herschel as part of the PACS Evolutionary Probe (PEP) and the Herschel Multi-tiered ...

  • High-resolution Millimeter Imaging of Submillimeter Galaxies 

    Tacconi, L. J., R. Neri, S. C. Chapman, R. Genzel, et al. 2006. "High-resolution Millimeter Imaging of Submillimeter Galaxies." The Astrophysical Journal 640(1): 228-240
    We present sub-arcsecond resolution IRAM PdBI interferometry of eight submillimeter galaxies at redshifts from 2 to 3.4, where we detect continuum at 1mm and/or CO lines at 3 and 1 mm. The CO 3-2/4-3 line profiles in five ...

  • Most Submillimetre Galaxies are Major Mergers 

    Engel, H., L. J. Tacconi, R. I. Davies, R. Neri, et al. 2010. "Most Submillimetre Galaxies are Major Mergers." The Astrophysical Journal 724(1):233.
    We analyse subarcsecond resolution interferometric CO line data for twelve sub-millimetre-luminous (S850um > 5mJy) galaxies with redshifts between 1 and 3, presenting new data for four of them. Morphologically and kinematically ...

  • A Search for Neutral Carbon towards two z=4.05 Submillimetre Galaxies, GN20 and GN20.2 

    Casey, C. M., S. C. Chapman, E. Daddi, H. Dannerbauer, et al. 2009. "A Search for Neutral Carbon towards two z=4.05 Submillimetre Galaxies, GN20 and GN20.2." Monthly Notices of the Royal Astronomical Society 400:670.
    Using the IRAM Plateau-de-Bure Interferometer (PdBI) we have searched for the upper fine structure line of neutral carbon (CI(2->1), nu_rest = 809 GHz) and 12CO(J=7->6) (nu_rest=806GHz) towards the submillimetre galaxies ...

  • Submillimeter Galaxies at z 2: Evidence for Major Mergers & Constraints on Lifetimes, IMF and CO-H2 Conversion Factor 

    Tacconi, L. J., R. Genzel, I. Smail, R. Neri, et al. 2008. "Submillimeter Galaxies at z 2: Evidence for Major Mergers & Constraints on Lifetimes, IMF and CO-H2 Conversion Factor." The Astrophysical Journal 680(1): 246-262
    We report sub-arcsecond resolution IRAM PdBI millimeter CO interferometry of four z~2 submillimeter galaxies (SMGs), and sensitive CO (3-2) flux limits toward three z 2 UV-/optically selected star forming galaxies. The new ...

  • A survey of molecular gas in luminous sub-millimetre galaxies 

    Bothwell, M. S., Ian Smail, S. C. Chapman, R. Genzel, et al. 2012. "A survey of molecular gas in luminous sub-millimetre galaxies." Monthly Notices of the Royal Astronomical Society 429(4): 3047.
    We present the results from a survey for 12CO emission in 40 luminous sub-millimetre galaxies (SMGs), with 850um fluxes of S850 = 4 - 20 mJy, conducted with the Plateau de Bure Interferometer. We detect 12CO emission in ...
