Abstract |
In this work we investigate the possible effect of the magnetic field in star
forming regions on galactic scales, using numerical simulations. We compare
two identical models with only one difference, the one is magnetised and the
other one is not. We find that there are differences in the gas distribution of
the two galaxies that persist with time. The differences are more pronounced
as time goes by. Also, the magnetised model forms slightly more dense gas and
has a slightly higher star formation rate. In order to investigate this difference
we turn to the molecular clouds and their properties. First, we identify the
molecular clouds using three algorithms. We find out that the first two rely
on resolution. Afterwards, we calculate the statistical properties of the clouds
for both models looking for potential differences. We find that the properties
are almost the same for the two models and consistent with observed molecular
cloud scaling relations.
