Numerical Analysis and Data Visualisation for Dark Matter Halos
The aim of this lab is to get some experience
in visualisation of large data sets, and the
packages that researchers commonly use for these
tasks. We will be doing this in the context of
exploring simulations of cosmological dark matter,
and specifically the analysis of dark matter (DM) halos.
A dark matter halo is a component of a galaxy that
permeates and extends beyond the visible galactic
disc, and, although invisible, it dominates the total
mass of most galaxies. Dark matter halos play a key
role in current models of galaxy formation and evolution,
and one of the main research approaches consists in N-body
simulations of the evolution of halos from initial density
perturbations in the early Universe. This is a fascinating
and rich topic in modern physics that brings together theory,
observation and computational research to address a number
of unanswered questions about our Universe.
In this lab, we will visualise the data from N-body simulations,
and identify and analyse the dark matter halos formed, as well
as investigating the theoretical background to such simulations.
