Computational issues in chemo-dynamical modelling of the formation and evolution of galaxies

Pascale Jablonka, Yves Revaz, Vivien François Bonvin, Alexis Arnaudon, Matthew Luke Nichols

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 continues to climb, these simulations are able to provide new constraints on ...

The post-infall evolution of a satellite galaxy

Pascale Jablonka, Yves Revaz, Matthew Luke Nichols

We describe a new method that only focuses on the local region surrounding an infalling dwarf in an effort to understand how the hot baryonic halo alters the chemodynamical evolution of dwarf galaxies. Using this method, we examine how a dwarf, similar to ...

Gravitational tides and dwarf spheroidal galaxies

Pascale Jablonka, Yves Revaz, Matthew Luke Nichols

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 Milky Way on the chemodynamical evolution of dwarf spheroidals that res ...

The Smith Cloud and its dark matter halo: survival of a Galactic disc passage

Matthew Luke Nichols

Under conservative assumptions about the Galaxy, the derived velocity of the Smith Cloud indicates that it will have undergone at least one passage of the Galactic disc. Using hydrodynamic simulations, we examine the present-day structure of the Smith Clou ...

The Epoch Of Assembly Of Two Galaxy Groups: A Comparative Study

Matthew Luke Nichols

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 levels of gas deficiency as the distance to their host decreases. The well es ...
