Probing Nuclear and Circumnuclear Properties of NGC 6300 using X-ray
  Observations
  We present the results obtained from a detailed X-ray timing and spectral
analysis of Seyfert 2 galaxy NGC 6300 by using observations with the {\it
Suzaku}, {\it Chandra} and {\it NuSTAR} observatories between 2007 and 2016. We
calculate variance, rms fractional variability of the source in different
energy bands and find variabilities in various energy bands. Spectral
properties of the source are studied by using various phenomenological and
physical models. The properties of the Compton clouds, reflection, Fe K$\alpha$
line emission and soft X-ray excess are studied in detail. Several physical
parameters of the source are extracted and investigated to establish the
presence/absence of any correlation between them. We also investigate the
nature of the circumnuclear `torus' and find that the torus is not uniform,
rather clumpy. The observed changes in the line-of-sight column density can be
explained in terms of transiting clouds. The iron line emitting region is found
to be different in the different epoch of observations. We also observe that
the torus and the nucleus independently evolve over the years.
