Abstract
This work presents a study of galactic outflows driven by stellar feedback. We extract mainsequence disc galaxies with stellar mass 109 ≤ M*/ M⊙ ≤ 5.7 × 1010 at redshift z = 0 from the highest resolution cosmological simulation of the Evolution and Assembly of GaLaxies and their Environments (EAGLE) set. Synthetic gas rotation velocity and velocity dispersion (σ) maps are created and compared to observations of disc galaxies obtained with the Sydney-AAO (Australian Astronomical Observatory) Multi-object Integral field spectrograph (SAMI), where σ-values greater than 150 km s-1 are most naturally explained by bipolar outflows powered by starburst activity. We find that the extension of the si..

Support for AMM is provided by NASA through Hubble Fellowship grant # HST-HF2-51377 awarded by the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., for NASA, under contract NAS5-26555. The SAMI Galaxy Survey is based on observations made at theAnglo-Australian Telescope. The Sydney-AAOMulti-object Integral field spectrograph (SAMI) was developed jointly by the University of Sydney and the AAO. The SAMI input catalogue is based on data taken from the Sloan Digital Sky Survey, the GAMA Survey and the VST ATLAS Survey. The SAMI Galaxy Survey is funded by the Australian Research Council Centre of Excellence for All-sky Astrophysics (CAASTRO), through project number CE110001020, and other participating institutions.

Part of this research was done using the National Computational Infrastructure (NCI) Raijin-distributed memory cluster and supported by the Flagship Allocation Scheme of the NCI National Facility at the Australian National University (ANU). For the post-processing, we used the Edward and Spartan High Performance Computing (HPC) clusters at the University of Melbourne. This work also used the DiRAC Data Centric system at Durham University, operated by the Institute for Computational Cosmology on behalf of the STFC DiRAC HPC Facility (http://dirac.ac.uk).
