Large scale galactic turbulence: can self-gravity drive the observed HI velocity dispersions?
Oscar Agertz, George Lake, Romain Teyssier +3
Observations of turbulent velocity dispersions in the HI component of galactic disks show a characteristic floor in galaxies with low star formation rates and within individual gal…
Discreteness Effects in Lambda Cold Dark Matter Simulations: A Wavelet-Statistical View
Alessandro B. Romeo, Oscar Agertz, Ben Moore +1
The effects of particle discreteness in N-body simulations of Lambda Cold Dark Matter (LambdaCDM) are still an intensively debated issue. In this paper we explore such effects, tak…
Thin, thick and dark discs in LCDM
J. I. Read, G. Lake, O. Agertz +1
In a LCDM cosmology, the Milky Way accretes satellites into the stellar disc. We use cosmological simulations to assess the frequency of near disc plane and higher inclination accr…
The Source of Ionization along the Magellanic Stream
J. Bland-Hawthorn, R. Sutherland, O. Agertz +1
Since its discovery in 1996, the source of the bright H-alpha emission (up to 750 mR) along the Magellanic Stream has remained a mystery. There is no evidence of ionising stars wit…
