A gap in phase-space, the loss cone (LC), is opened
up by a supermassive black hole (MBH) as it disrupts
or accretes stars in a galactic centre. If a star
enters the LC then, depending on its properties, its
interaction with the MBH will either generate a
luminous electromagnetic flare or give rise to
gravitational radiation, both of which are expected
to have directly observable consequences.
The thesis begins with a brief review of dynamical
modelling collisionless galaxies. Then the general
scheme is developed to construct high-resolution
N-body models. Next, a suit of optimized model and
code, both having high-resolution at the centre, are
used follow the evolution of flyby encounters for a
broad range of satellite parameters. The penultimate
chapter describes how the findings are used to
predict a MBH fuelling rate driven by orbiting
substructures within the dark matter halo. Finally, I
summarize the findings and provide some future work.
