Description
Active Galactic Nuclei (AGN) are compact
and highly luminous regions at the centre of galaxies. Relativistic
jets from radio loud AGN have been shown to exhibit variability over
various time-scales and frequencies. A contributing component to the
formation of variability results from the injection and propagation of
blob/shock structures within the jet. We have investigated this
through three-dimensional RMHD simulations jets using PLUTO. A
constant jet was first allowed to develop in time forming multiple
re-collimation shocks, before a quasi-spherical blob was injected and
allowed to propagate along the jet, with blob-jet interactions
occurring along the propagation path. A post-processing code was used
to find the integrated specific intensity of the synchrotron emission
in the radio regime, accounting for Doppler boosting and
light-crossing time correction. Different types of blob injection were
tested, investigating the resulting light curves.
