    Angular clustering of z ∼ 2 star-forming and passive galaxies in 2.5 square degrees of deep CFHT imaging 
    Sato, Taro; Sawicki, Marcin, 1969-; Arcila-Osejo, Liz Maria (Oxford University PressRoyal Astronomical Society, 2014)
    We study the angular clustering of z ∼ 2 galaxies using ∼40 000 star-forming (SF) and ∼5000 passively evolving (PE) galaxies selected from ∼2.5 deg[superscript 2] of deep (K[subscript lim] = 23–24 AB) Canada–France–Hawaii ...

    The effect of the cosmic web on cluster weak lensing mass estimates 
    Loken, Chris; Metzler, Christopher A.; White, Martin (American Astronomical SocietyIOP Publishing, 2001-02-01)
    In modern hierarchical theories of structure formation, rich clusters of galaxies form at the vertices of a weblike distribution of matter, with filaments emanating from them to large distances and with smaller objects ...

    The environmental dependence of neutral hydrogen in the GIMIC simulations 
    Cunnama, D.; Andrianomena, S.; Cress, C. M.; Faltenbacher, A.; Gibson, Brad K.; Theuns, T. (Oxford University Press, 2014-01-10)
    We use the Galaxies-Intergalactic Medium Interaction Calculation (GIMIC) cosmological hydrodynamic simulation at z = 0 to study the distribution and environmental dependence of neutral hydrogen (H I) gas in the outskirts ...

    Hybrid cosmological simulations with stream velocities 
    Richardson, Mark L. A.; Scannapieco, Evan; Thacker, Robert John, 1970- (American Astronomical Society, 2013-07-10)
    In the early universe, substantial relative “stream” velocities between the gas and dark matter arise due to radiation pressure and persist after recombination. To assess the impact of these velocities on high-redshift ...

    On the estimation and detection of the Rees–Sciama effect 
    Fullana, M. J.; Arnau, J. V.; Thacker, Robert John, 1970-; Couchman, H. M. P.; Sáez, D. (Oxford University Press, 2017-02)
    Maps of the Rees–Sciama (RS) effect are simulated using the parallel N-body code, hydra, and a run-time ray-tracing procedure. A method designed for the analysis of small, square cosmic microwave background (CMB) maps is ...

    On the lack of correlation between [O iii]/[O ii] and Lyman continuum escape fraction 
    Bassett, R.; Ryan-Weber, E. V.; Cooke, Jeffery; Diaz, C. G.; Nanayakkara, T.; Yuan, T. T.; Spitler, L. R.; Meštrić, U.; Garel, T.; Sawicki, Marcin, 1969-; Gwyn, S.; Golob, Anneya (Oxford University PressRoyal Astronomical Society, 2019-03)
    We present the first results of our pilot study of eight photometrically selected Lyman-continuum (LyC) emitting galaxy candidates from the COSMOS field and focus on their optical emission line ratios. Observations were ...

    The SCUBA-2 Cosmology Legacy Survey: 850 μm maps, catalogues and number counts 
    Geach, J. E.; Dunlop, J. S.; Halpern, M.; Smail, Ian; van der Werf, P.; Alexander, D. M.; Almaini, O.; Aretxaga, I.; Arumugam, V.; Asboth, V.; Banerji, M.; Beanlands, J.; Best, P. N.; Blain, A. W.; Birkinshaw, M.; Chapin, E. L.; Chapman, S. C.; Chen, C-C.; Chrysostomou, A.; Clarke, C.; Clements, D. L.; Conselice, C.; Coppin, K. E. K.; Cowley, W. I.; Danielson, A. L. R.; Eales, S.; Edge, A. C.; Farrah, D.; Gibb, A.; Harrison, C. M. (Oxford University Press, 2017-02)
    We present a catalogue of ∼3000 submillimetre sources detected (≥3.5σ) at 850 μm over ∼5 deg2 surveyed as part of the James Clerk Maxwell Telescope (JCMT) SCUBA-2 Cosmology Legacy Survey ...

    The stellar metallicity distribution of disc galaxies and bulges in cosmological simulations 
    Gibson, Brad K.; Calura, F.; Michel-Dansac, L.; Stinson, G. S.; Dotter, A.; Pilkington, K.; House, E. L.; Brook, C. B.; Few, C. G.; Cignoni, M. (Royal Astronomical Society, 2012-12)
    By means of high-resolution cosmological hydrodynamical simulations of Milky Way (MW) like disc galaxies, we conduct an analysis of the associated stellar metallicity distribution functions (MDFs). After undertaking a ...
