Morphology and Evolution of Radio Galaxies

Author(s): Najmuj Sahadat Sarkar

This paper is mainly on radio galaxies. Some brief information is given here so that we can better search or analyze various issues related to radio galaxies, such as their morphology, evolution and dynamic properties. What is Active Galactic Nucleus or AGN, what are FR-l and FR-ll radio galaxies, for what reason are radio zets ejected from AGN, how far are they able to travel, what is the total life span of zets, what is their luminosity form, various structural aspects of the galaxy, including many other important information which are apparently sight we do not know or due to observational weakness could not understand properly. At the end of the paper there are some mathematical details, related to luminosity, radio power, zets velocity, etc.
