    • Predictions for the CO emission of galaxies from a coupled simulation of galaxy formation and photon-dominated regions 

      Lagos, Claudia del P.; Bayet, Estelle; Baugh, Carlton M.; Lacey, Cedric G.; Bell, Tom A.; Fanidakis, Nikolaos; Geach, James E. (2012-11)
      We combine the galaxy formation model galform with the photon-dominated region code ucl-pdr to study the emission from the rotational transitions of 12CO (CO) in galaxies from z = 0 to z = 6 in the ?cold dark matter ...

    • A relationship between specific star formation rate and metallicity gradient within z ~ 1 galaxies from KMOS-HiZELS 

      Stott, John P.; Sobral, David; Swinbank, A. M.; Smail, Ian; Bower, Richard; Best, Philip N.; Sharples, Ray M.; Geach, James E.; Matthee, Jorryt (2014-09-21)
      We have observed a sample of typical z ~ 1 star-forming galaxies, selected from the HiZELS survey, with the new K-band Multi-Object Spectrograph (KMOS) near-infrared, multi-integral field unit instrument on the Very Large ...

    • Reproducing sub-millimetre galaxy number counts with cosmological hydrodynamic simulations 

      Lovell, Christopher C.; Geach, James E.; Davé, Romeel; Narayanan, Desika; Li, Qi (2021-01-04)
      Matching the number counts of high-$z$ sub-millimetre-selected galaxies (SMGs) has been a long standing problem for galaxy formation models. In this paper, we use 3D dust radiative transfer to model the sub-mm emission ...

    • The SCUBA-2 Cosmology Legacy Survey: blank-field number counts of 450-mu m-selected galaxies and their contribution to the cosmic infrared background 

      Geach, James E.; Chapin, E.L.; Coppin, Kristen; Dunlop, J. S.; Halpern, M.; Smail, Ian; van der Werf, P.; Serjeant, S.; Farrah, D.; Roseboom, I.; Targett, T.; Arumugam, V.; Asboth, V.; Blain, A.; Chrysostomou, A.; Clarke, C.; Ivison, R. J.; Jones, S. L.; Karim, A.; Mackenzie, T.; Meijerink, R.; Michalowski, M. J.; Scott, Douglas; Simpson, J. M.; Swinbank, A.M.; Alexander, D.M.; Almaini, O.; Aretxaga, I.; Best, P.; Chapman, S.; Clements, D. L.; Conselice, C.; Danielson, A. L. R.; Eales, S.; Edge, A.C.; Gibb, A. G.; Hughes, D.; Jenness, T.; Knudsen, K. K.; Lacey, C. G.; Marsden, G.; McMahon, R.; Oliver, S. J.; Page, M. J.; Peacock, J.A.; Rigopoulou, D.; Robson, E.I.; Spaans, M.; Stevens, J.; Webb, T. M. A.; Willott, C.; Wilson, C. D.; Zemcov, M. (2013-06)
      The first deep blank-field 450 mu m map (1 sigma approximate to 1.3 mJy) from the Submillimetre Common-User Bolometer Array-2 SCUBA-2 Cosmology Legacy Survey (S2CLS), conducted with the James Clerk Maxwell Telescope (JCMT) ...

    • The Space Density of Intermediate-redshift, Extremely Compact, Massive Starburst Galaxies 

      Whalen, Kelly E.; Hickox, Ryan C.; Coil, Alison L.; Diamond-Stanic, Aleksandar M.; Geach, James E.; Moustakas, John; Rudnick, Gregory H.; Rupke, David S. N.; Sell, Paul H.; Tremonti, Christy A.; Davis, Julie D.; Perrotta, Serena; Petter, Grayson C. (2022-10-28)
      We present a measurement of the intrinsic space density of intermediate-redshift (z ∼ 0.5), massive (M * ∼ 1011 M ⊙), compact (R e ∼ 100 pc) starburst (ΣSFR ∼ 1000 M ⊙ yr−1 kpc−1) galaxies with tidal features indicative ...
