  • Polytropic model fits to the globular cluster NGC 2419 in Modified Newtonian Dynamics 

    Ibata, Rodrigo, Antonio Sollima, Carlo Nipoti, Michele Bellazzini, et al. 2011. "Polytropic model fits to the globular cluster NGC 2419 in Modified Newtonian Dynamics." The Astrophysical Journal 743:43.
    We present an analysis of the globular cluster NGC 2419, using a polytropic model in Modified Newtonian Dynamics (MOND) to reproduce recently published high quality data of the structure and kinematics of the system. We ...
  • The Properties of Sub-mm Galaxies in Hierarchical Models 

    Swinbank, Mark, Cedric Lacey, Ian Smail, Carlton Baugh, et al. 2008. "The Properties of Sub-mm Galaxies in Hierarchical Models." Monthly Notices of the Royal Astronomical Society 391: 420.
    We use the combined GALFORM semi-analytical model of galaxy formation and GRASIL spectrophotometric code to investigate the properties of galaxies selected via their sub-mm emission. Our fiducial model has previously been ...
  • Radio imaging of the Subaru/XMM-Newton Deep Field - III. Evolution of the radio luminosity function beyond z=1 

    Simpson, Chris, Steve Rawlings, Rob Ivision, Masayuki Akiyama, et al. 2012. "Radio imaging of the Subaru/XMM-Newton Deep Field - III. Evolution of the radio luminosity function beyond z=1." Monthly Notices of the Royal Astronomical Society 421:3060.
    We present spectroscopic and eleven-band photometric redshifts for galaxies in the 100-uJy Subaru/XMM-Newton Deep Field radio source sample. We find good agreement between our redshift distribution and that predicted by ...
  • Rest-frame optical and far-infrared observations of extremely bright Lyman-break galaxy candidates at z ~ 2.5 

    Ivison, Rob, Ian Smail, Misty Bentz, Jason Stevens, et al. 2005. "Rest-frame optical and far-infrared observations of extremely bright Lyman-break galaxy candidates at z ~ 2.5." Monthly Notices of the Royal Astronomical Society 362(2): 535-541
    We have investigated the rest-frame optical and far-infrared properties of a sample of extremely bright candidate Lyman-break galaxies (LBG) identified in the Sloan Digital Sky Survey. Their high ultraviolet luminosities ...
  • The Rest-frame Optical Spectra of SCUBA Galaxies 

    Swinbank, Mark, Ian Smail, Scott Chapman, Andrew Blain, et al. 2004. "The Rest-frame Optical Spectra of SCUBA Galaxies." The Astrophysical Journal 616(1): 71-85
    We present near-infrared spectroscopy and narrow-band imaging at the wavelength of redshifted H-alpha for a sample of 30 high-redshift, far-infrared luminous galaxies. This sample is selected from surveys in the sub-millimeter, ...
  • The SCUBA HAlf Degree Extragalactic Survey (SHADES) - IV: Radio-mm-FIR photometric redshifts 

    Aretxaga, Itziar, David H. Hughes, Kristen Coppin, Angela M. J. Mortier, et al. 2007. "The SCUBA HAlf Degree Extragalactic Survey (SHADES) - IV: Radio-mm-FIR photometric redshifts." Monthly Notices of the Royal Astronomical Society 379(4): 1571-1588
    We present the redshift distribution of the SHADES galaxy population based on the rest-frame radio-mm-FIR colours of 120 robustly detected 850um sources in the Lockman Hole East (LH) and Subaru XMM-Newton Deep Field (SXDF). ...
  • The SCUBA HAlf Degree Extragalactic Survey (SHADES) -- VI. 350 micron mapping of submillimetre galaxies 

    Coppin, Kristen, Mark Halpern, Douglas Scott, Colin Borys, et al. 2008. "The SCUBA HAlf Degree Extragalactic Survey (SHADES) -- VI. 350 micron mapping of submillimetre galaxies." Monthly Notices of the Royal Astronomical Society 384(4):1597-1610
    A follow-up survey using the Submillimetre High-Angular Resolution Camera (SHARC-II) at 350 microns has been carried out to map the regions around several 850 micron-selected sources from the Submillimetre HAlf Degree ...
  • A SCUBA Scanmap of the Hubble Deep Field: Measuring the bright end of the sub-mm source counts 

    Borys, Colin, Scott Chapman, Mark Halpern, and Douglas Scott. 2002. "A SCUBA Scanmap of the HDF: Measuring the bright end of the sub-mm source counts." Monthly Notices of the Royal Astronomical Society 330(3): 63-L67
    Using the 850 micron SCUBA camera on the JCMT and a scanning technique different from other sub-mm surveys, we have obtained a 125 square arcminute map centered on the Hubble Deep Field. The one-sigma sensitivity to point ...
  • A submillimetre galaxy at z=4.76 in the LABOCA survey of the Extended Chandra Deep Field South 

    Coppin, Kristen, Ian Smail, David M. Alexander, Axel Weiss, et al. 2009. "A submillimetre galaxy at z=4.76 in the LABOCA survey of the Extended Chandra Deep Field South." 395(4): 1905-1914
    We report on the identification of the highest redshift submm-selected source currently known: LESSJ033229.4-275619. This source was detected in the Large Apex BOlometer CAmera (LABOCA) Extended Chandra Deep Field South ...
