(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 ...

(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, ...

(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 ...

(Halifax, N.S. : Saint Mary's University, 2013 [i.e. 2012]., 2012)This thesis examines the formation and evolution of cold gaseous structures in galaxies and galactic outflows in two distinct scenarios. Previous analytic estimates of the viscous time-scale due to cloud-cloud collisions ...
