ABSTRACT
- In order to search for Supernova Remnants (SNRs) and understand the
origin of the turbulent gas in Giant H II Regions (GHR), we have taken
radio, optical and X-ray observations of several GHRs. The kinematics of
the GHRs are studies using TAURUS imaging Fabry-Perot interferometer and
echelle spectroscopy in H-alpha lambda(6563), [O III] lambda(5007) and
[S II] lambda(6717), lambda(6731) emission lines. Radio continuum observations
of the GHRs are taken to detect the synchrotron radiation from SNRs. Since
X-ray emission traces the hot gas in the interstellar medium, the diffuse
X-ray emission detected in the GHRs can be the indicator of the existence
in SNRs. Different mechanisms which may cause the turbulence in the GHRs
are studies. The important role of SNR in influencing the kinetics of the
gas is also investigated in this thesis.
