Full N-body models (with local cuts)

These are full collisionless N-body simulations. The first two were published and analysed in http://adsabs.harvard.edu/abs/2011MNRAS.416.2318G and http://adsabs.harvard.edu/abs/2012MNRAS.425.1445G. The latter two include a perturbing satellite at low and high inclination.

There are four simulations:

Each simulation includes:

  • densityfalloff_dm/stars :: ASCII file data for the dark matter/star density fall-off at different radii and angle for small volumes around the disc.
  • surfacedensity_bar/dm :: As above for the surface density for the baryons and dark matter.
  • velocity dispersion :: As above for the stellar velocity dispersion in the z-direction (perpendicular to the disc).
  • wedges :: Raw unbinned ASCII data for different wedges cut around the disc as in http://adsabs.harvard.edu/abs/2011MNRAS.416.2318G.
  • *.txt.gz :: Raw ASCII data for the entire centred and aligned simulations (excluding the accreted satellite stars and dark matter). Warning: These files are large (>2 GB).
  • *.tip :: Tipsy format binary file containing all simulation data. Warning :: these files have not been centred or aligned. Tools for reading, centring and aligning these data can be found in the PyNbody suite here.
