    Cloud angular momentum and effective viscosity in global SPH simulations with feedback 
    Williamson, David John; Thacker, Robert John, 1970-; Wurster, James Howard; Gibson, Brad K. (Oxford University Press, 2014-08-21)
    We examine simulations of isolated galaxies to analyse the effects of localized feedback on the formation and evolution of molecular clouds. Feedback contributes to turbulence and the destruction of clouds, leading to a ...

    Effective viscosity from cloud–cloud collisions in 3D global smoothed particle hydrodynamics simulations 
    Williamson, David John; Thacker, Robert John, 1970- (Oxford Academic, 2012-04)
    Analytic estimates of the viscous time-scale due to cloud–cloud collisions have been as high as thousands of Gyr. Consequently, cloud collisions are widely ignored as a source of viscosity in galactic discs. However, ...

    Embedded protostellar disks around (sub-)solar stars. II. Disk masses, sizes, densities, temperatures, and the planet formation perspective 
    Vorobyov, Eduard I. (IOP Publishing Limited, 2011-03-10)
    We present basic properties of protostellar disks in the embedded phase of star formation (EPSF), which is difficult to probe observationally using available observational facilities. We use numerical hydrodynamics simulations ...

    High-velocity-dispersion cold gas in ULIRG Outflows – I. Direct simulations 
    Williamson, David John; Thacker, Robert John, 1970-; Scannapieco, E.; Bruggen, M. (Oxford University Press, 2014-06)
    Observations (e.g. Phillips, Heckman et al., Martin) have revealed cold gas with large velocity dispersions (≈300 km s−1) within the hot outflows of ultraluminous infrared galaxies (ULIRGs). This gas ...

    The large globule Lynds 810 as a possible member of the Vulpecula OB1 complex 
    Turner, David Gerald, 1945- (EDP Sciences, 1986-10)
    A distance of 2.5 [plus or minus] 0.2 kpc is derived for the dark globule Lynds 810 using photometric data for foreground stars and star counts. It is argued that this globule is likely to belong to the Vul OB1 complex. ...

    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 role of feedback in shaping the structure of the interstellar medium 
    Walker, A. P.; Gibson, Brad K.; Pilkington, K.; Brook, C. B.; Dutta, P.; Stanimirovic, S.; Stinson, G. S.; Bailin, J. (Oxford University Press, 2014-06)
    We present an analysis of the role of feedback in shaping the neutral hydrogen (H I) content of simulated disc galaxies. For our analysis, we have used two realizations of two separate Milky Way-like (∼L★) discs – ...

    The star-forming core of Monoceros R2 
    Giannakopoulou, Jean; Mitchell, George F.; Hasegawa, Tatsuhiko I.; Matthews, Henry E.; Maillard, Jean-Pierre (American Astronomical Society, 1997-09)
    The central region of the Monoceros R2 molecular cloud has been studied using molecular line maps, maps in continuum emission, and an M-band (4.7 [micrometres]) absorption spectrum toward Mon R2 IRS 3. Maps were made in ...
