We investigate the enhancement of star formation efficiency in galaxy interactions and
mergers by numerical simulations of several hundred galaxy collisions. All morphological …

We investigate the formation and evolution of giant molecular clouds (GMCs) in a Milky-Way-
like disk galaxy with a flat rotation curve. We perform a series of three-dimensional adaptive …

We have developed a new scheme to treat a multiphase interstellar medium in smoothed
particle hydrodynamics simulations of galaxy formation. This scheme can represent a co …

ABSTRACT A sample of very high resolution cosmological disk galaxy simulations is used to
investigate the evolution of galaxy disk sizes back to redshift 1 within the ΛCDM cosmology …

Using cosmological galaxy formation simulations from the MaGICC (Making Galaxies in a
Cosmological Context) project, spanning stellar mass from∼ 107 to 3× 1010 M⊙, we trace …

The latest generation of cosmological simulations are on the verge of being able to resolve
the structure of bulges for the first time. Hence, we review the current state of bulge formation …

We present moderate-resolution spectroscopy of extraplanar diffuse ionized gas (EDIG)
emission in the edge-on spiral galaxy NGC 4302. The spectra were obtained with the …

Context. The mass-metallicity (MZ) relation in star-forming galaxies at all redshifts has been
recently established. It is therefore important to understand the physical mechanisms …

Context. The majority of galactic chemical evolution models assumes the instantaneous
mixing approximation (IMA). This assumption is probably not realistic, as indicated by the …

We describe simulations of the response of a gaseous disc to an active spiral potential. The
potential is derived from an N-body calculation and leads to a multi-armed time-evolving …
