  • Galaxy and Mass Assembly (GAMA) : the life and times of L-star galaxies 

    Robotham, A. S. G.; Liske, J.; Driver, S. P.; Sansom, A. E.; Baldry, I. K.; Bauer, A. E.; Bland-Hawthorn, J.; Brough, S.; Brown, M. J. I.; Colless, M.; Christodoulou, L.; Drinkwater, M. J.; Grootes, M. W.; Hopkins, A. M.; Kelvin, L. S.; Norberg, P.; Loveday, J.; Phillipps, S.; Sharp, R.; Taylor, E. N.; Tuffs, R. J. (2013-05-01) - Journal article
    In this work, we investigate in detail the effects the local environment (groups and pairs) has on galaxies with stellar mass similar to the Milky Way (L* galaxies). A volume limited sample of 6150 galaxies are visually ...
  • Galaxy And Mass Assembly (GAMA) : ugrizYJHK Sersic luminosity functions and the cosmic spectral energy distribution by Hubble type 

    Kelvin, Lee S.; Driver, Simon P.; Robotham, Aaron S. G.; Graham, Alister W.; Phillipps, Steven; Agius, Nicola K.; Alpaslan, Mehmet; Baldry, Ivan; Bamford, Steven P.; Bland-Hawthorn, Joss; Brough, Sarah; Brown, Michael J. I.; Colless, Matthew; Conselice, Christopher J.; Hopkins, Andrew M.; Liske, Jochen; Loveday, Jon; Norberg, Peder; Pimbblet, Kevin A.; Popescu, Cristina C.; Prescott, Matthew; Taylor, Edward N.; Tuffs, Richard J. (2014-04-01) - Journal article
    We report the morphological classification of 3727 galaxies from the Galaxy and Mass Assembly survey with Mr < −17.4 mag and in the redshift range 0.025 < z < 0.06 (2.1 × 105 Mpc3) into E, S0-Sa, SB0-SBa, Sab-Scd, SBab-SBcd, ...
  • Modified Newtonian dynamics at all astrophysical scales 

    Angus, Garry W. (University of St Andrews, 2008-11-27) - Thesis
    In this thesis I test the modified Newtonian dynamics as an alternative to the cold dark matter hypothesis. In the Milky Way, I show that the dynamics of the dwarf galaxies are well described by the paradigm and I confirm ...
  • Photoionization and heating of a supernova-driven turbulent interstellar medium 

    Barnes, J. E.; Wood, Kenneth; Hill, Alex S.; Haffner, L. M. (2014-06-01) - Journal article
    The diffuse ionized gas (DIG) in galaxies traces photoionization feedback from massive stars. Through three-dimensional photoionization simulations, we study the propagation of ionizing photons, photoionization heating and ...
