    • An ALMA survey of the SCUBA-2 CLS UDS field: physical properties of 707 sub-millimetre galaxies 

      Dudzevičiūtė, U.; Smail, Ian; Swinbank, A. M.; Stach, S. M.; Almaini, O.; Cunha, E. da; An, Fang Xia; Arumugam, V.; Birkin, J.; Blain, A. W.; Chapman, S. C.; Conselice, C. J.; Coppin, K. E. K.; Dunlop, J. S.; Farrah, D.; Geach, J. E.; Gullberg, B.; Hartley, W. G.; Hodge, J. A.; Ivison, R. J.; Maltby, D. T.; Scott, D.; Simpson, C. J.; Walter, F.; Wardlow, J. L.; Weiss, A.; Werf, P. van der (2020-05)
      We analyse the physical properties of a large, homogeneously selected sample of ALMA-located sub-mm galaxies (SMGs) detected in the SCUBA-2 CLS 850-$\mu$m map of the UKIDSS/UDS field. This survey, AS2UDS, identified 707 ...

    • Cosmic evolution of the H2 mass density and the epoch of molecular gas 

      Garratt, T. K.; Coppin, K. E. K.; Geach, J. E.; Almaini, O.; Hartley, W. G.; Maltby, D. T.; Simpson, C. J.; Wilkinson, A.; Conselice, C. J.; Franco, M.; Ivison, R. J.; Koprowski, M. P.; Lovell, C. C.; Pope, A.; Scott, D.; Werf, P. van der (2021-05-05)
      We present new empirical constraints on the evolution of ρ H2, the cosmological mass density of molecular hydrogen, back to z ≈ 2.5. We employ a statistical approach measuring the average observed 850 μm flux density of ...

    • The SCUBA-2 cosmology legacy survey : ALMA resolves the rest-frame far-infrared emission of sub-millimeter galaxies 

      Simpson, J. M.; Smail, Ian; Swinbank, A.M.; Almaini, O.; Blain, A. W.; Bremer, M.N.; Chapman, S.C.; Chen, Chian Chou; Conselice, C.; Coppin, Kristen; Danielson, A. L. R.; Dunlop, J. S.; Edge, A. C.; Farrah, D.; Geach, James; Hartley, W. G.; Ivison, R. J.; Karim, A.; Lani, C.; Ma, C. J.; Meijerink, R.; Michałowski, M. J.; Mortlock, A.; Scott, D.; Simpson, C. J.; Spaans, M.; Thomson, A. P.; van Kampen, E.; Van Der Werf, P. P. (2015-01-16)

    • The SCUBA-2 Cosmology Legacy Survey: Multi-wavelength Properties of ALMA-identified Submillimeter Galaxies in UKIDSS-UDS 

      Simpson, J. M.; Smail, Ian; Swinbank, A. M.; Ivison, R. J.; Dunlop, J. S.; Geach, J. E.; Almaini, O.; Arumugam, V.; Bremer, M. N.; Chen, Chian-Chou; Conselice, C.; Coppin, K. E. K.; Farrah, D.; Ibar, E.; Hartley, W. G.; Ma, C. J.; Michalowski, M. J.; Spaans, M.; Thomson, A. P.; Werf, P. P. van der (2017-04-13)
      We present a multi-wavelength analysis of 52 sub-millimeter galaxies (SMGs), identified using ALMA 870$\mu$m continuum imaging in a pilot program to precisely locate bright SCUBA2-selected sub-mm sources in the UKIDSS Ultra ...

    • Transfer learning for galaxy morphology from one survey to another

C.; Tarle, G.; Walker, A. R.; Zuntz, J. (2018-12-28)
      Deep Learning (DL) algorithms for morphological classification of galaxies have proven very successful, mimicking (or even improving) visual classifications. However, these algorithms rely on large training samples of ...

    • Why z > 1 radio-loud galaxies are commonly located in protoclusters 

      Hatch, N. A.; Wylezalek, D.; Kurk, J. D.; Stern, D.; Breuck, C. De; Jarvis, M.J.; Galametz, A.; Gonzalez, A. H.; Hartley, W. G.; Mortlock, A.; Seymour, N.; Stevens, J. A. (2014-11-21)
      Distant powerful radio-loud active galactic nuclei (RLAGN) tend to reside in dense environments and are commonly found in proto-clusters at z > 1.3. We examine whether this occurs because RLAGN are hosted by massive galaxies, ...
