    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 CO and radio imaging of ULIRGs: extended CO structures, and implications for the universal star formation law

    We present high spatial resolution (0.4", ~3.5 kpc) PdBI interferometric data on three ultra-luminous infrared galaxies (ULIRGs) at z~2: two submillimetre galaxies and one submillimetre faint star forming radio galaxy. The ...

  • 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 ...

  • Interferometric CO Observations of submillimeter-faint, radio-selected starburst galaxies at z~2 

    Chapman, S. C., R. Neri, F. Bertoldi, Ian Smail, et al. 2008. "Interferometric CO Observations of submillimeter-faint, radio-selected starburst galaxies at z~2." The Astrophysical Journal 689(2): 889-896
    High-redshift, dust-obscured galaxies -- selected to be luminous in the radio but relatively faint at 850um -- appear to represent a different population from the ultra-luminous submillimeter- (submm-) bright population. ...

  • An interferometric CO survey of luminous submm galaxies 

    Greve, T. R., F. Bertoldi, Ian Smail, R. Neri, et al. 2005. "An interferometric CO survey of luminous submm galaxies." Monthly Notices of the Royal Astronomical Society 359(3): 1165-1183
    In this paper we present results from an IRAM Plateau de Bure millimetre-wave Interferometer (PdBI) survey for CO emission towards radio-detected submillimetre galaxies (SMGs) with known optical and near-infrared spectroscopic ...

  • Interferometric Observations of Powerful CO Emission from the three Submillimeter Galaxies at z=2.30, 2.51 and 3.35 

    Neri, R., R. Genzel, R. J. Ivison, F. Bertoldi, et al. 2003. "Interferometric Observations of Powerful CO Emission from the three Submillimeter Galaxies at z=2.30, 2.51 and 3.35." The Astrophysical Journal 597(2): 113-L116. 10.1086/379968
    We report IRAM Plateau de Bure, millimeter interferometry of three z=~2.4 to 3.4, SCUBA deep field galaxies. Our CO line observations confirm the rest-frame UV/optical redshifts, thus more than doubling the number of ...

  • The LABOCA survey of the Extended Chandra Deep Field South: Two modes of star formation in AGN hosts? 

    Lutz, D., V. Mainieri, D. Rafferty, L. Shao, et al. 2010. "The LABOCA survey of the Extended Chandra Deep Field South: Two modes of star formation in AGN hosts?." The Astrophysical Journal 712(2):1287.
    We study the co-existence of star formation and AGN activity in X-ray selected AGN by analyzing stacked 870um submm emission from a deep and wide map of the Extended Chandra Deep Field South, obtained with LABOCA at the ...

  • Molecular Gas in Submillimetre-Faint, Star-Forming Ultraluminous Galaxies at z>1
