Origin of the Metallicity Distribution in the Thick Disc

Maider S. Miranda, Kate Pilkington, Brad K. Gibson +9

Aims. Using a suite of cosmological chemodynamical disc galaxy simulations, we assess how (a) radial metallicity gradients evolve with scaleheight; (b) the vertical metallicity gra…

A unified framework for the orbital structure of bars and triaxial ellipsoids

Monica Valluri, Juntai Shen, Caleb G. Abbott +1

We examine a large random sample of orbits in self-consistent simulations of N-body bars. Orbits in the bars are classified both visually and with a new automated orbit classificat…

The AIMSS Project III: The Stellar Populations of Compact Stellar Systems

Joachim Janz, Mark A. Norris, Duncan A. Forbes +11

In recent years, a growing zoo of compact stellar systems (CSSs) have been found whose physical properties (mass, size, velocity dispersion) place them between classical globular c…

Spiral arm kinematics for Milky Way stellar populations

S. Pasetto, G. Natale, D. Kawata +3

We present a new theoretical population synthesis model (the Galaxy Model) to examine and deal with large amounts of data from surveys of the Milky Way and to decipher the present…

H-ATLAS/GAMA: The nature and characteristics of optically red galaxies detected at submillimetre wavelengths

A. Dariush, S. Dib, S. Hony +39

We combine Herschel/SPIRE sub-millimeter (submm) observations with existing multi-wavelength data to investigate the characteristics of low redshift, optically red galaxies detecte…

Imprints of radial migration on the Milky Way's metallicity distribution functions

Sarah R. Loebman, Victor P. Debattista, David L. Nidever +5

Recent analysis of the SDSS-III/APOGEE Data Release 12 stellar catalogue has revealed that the Milky Way's metallicity distribution function (MDF) changes shape as a function of ra…
