A detailed study of magnetized astrophysical ows has been carried out in the magnetohydrodynamic and special relativistic magneto- hydrodynamic regime. We have considered the thermodynamics of the ow to be described ...

Active Galactic Nuclei (AGN) are small regions in centers of some galaxies which emit powerful electromagnetic radiation, often outshining stars, gas, and dust which make up the host galaxy. These are the brightest ...

The variability in the physical/optical and chemical properties of aerosols showedthe different kinds of dynamical aspects on the regional and globalscales. Thestudies of dynamical aspects of aerosols over a high altitude ...

Star formation is a process by which dilute gas converted to stellar systems forming stars, which are the potential cradles of life. Almost all the radiant mass in the Galaxy is in the form of the star that formed ...

In view of the vital role of trace gases in atmospheric chemistry, air quality and climate change, this thesis has been aimed to understand the variations in troposheric ozone and its precursor gases such as CO, NOy and ...
