Computational issues in chemo-dynamical modelling of the formation and evolution of galaxies
Yves Revaz, Alexis Arnaudon, Matthew Nichols +2
Chemo-dynamical N-body simulations are an essential tool for understanding the formation and evolution of galaxies. As the number of observationally determined stellar abundances c…
The post-infall evolution of a satellite galaxy
Matthew Nichols, Yves Revaz, Pascale Jablonka
As galaxy simulations increase in resolution more attention is being paid towards the evolution of dwarf galaxies and how the simulations compare to observations. Despite this incr…
The Smith Cloud and its dark matter halo: Survival of a Galactic disc passage
Matthew Nichols, Nestor Mirabal, Oscar Agertz +2
The current velocity of the Smith Cloud indicates that it has undergone at least one passage of the Galactic disc. Using hydrodynamic simulations we examine the present day structu…
The effect of gravitational tides on dwarf spheroidal galaxies
Matthew Nichols, Yves Revaz, Pascale Jablonka
The effect of the local environment on the evolution of dwarf spheroidal galaxies is poorly understood. We have undertaken a suite of simulations to investigate the tidal impact of…
The Epoch of Assembly of Two Galaxy Groups: A comparative study
Matthew Nichols, Joss Bland-Hawthorn
Nearby galaxy groups of comparable mass to the Local Group show global variations that reflect differences in their evolutionary history. Satellite galaxies in groups have higher l…
Gas depletion in Local Group dwarfs on ~250 kpc scales: Ram pressure stripping assisted by internal heating at early times
Matthew Nichols, Joss Bland-Hawthorn
A recent survey of the Galaxy and M31 reveals that more than 90% of dwarf galaxies within 270 kpc of their host galaxy are deficient in HI gas. At such an extreme radius, the coron…
The Smith Cloud: high-velocity accretion and dark-matter confinement
M. Nichols, J. Bland-Hawthorn
The Smith Cloud is a massive system of metal-poor neutral and ionized gas M_gas >= 2x10^6 M_sun) that is presently moving at high velocity (V_GSR ~300 km s^-1) with respect to the…
