\subsection{Black holes and Active Galactic Nuclei}  It is widely accepted that there is a supermassive black hole (SMBH ) (with a mass ranging from $10^5$ – $10^{10}$ solar masses) at the centre center  of most galaxies , though the there is some uncertainty about how these black holes are formed. Black holes are regions of space-time exhibiting strong gravitational pull. According to (A Loeb) a black hole is the end product from the complete gravitational collapse of a material object, such as a massive star. The black hole is responsible for the mass concentration at the centre center  of each galaxy. Black holes found at the centre center  of galaxies are referred to as Super Massive Black Holes (SMBH). SMBH grow by merging with other black holes or by accretion of matter which is the process of attracting mater via a gravitational force leading to a growth of the attracting agent. Radio galaxies are galaxies dominated by radio emissions from jets stemming from SMBHs. AGN are the small, dense and luminous components of the centres of galaxies as represented in figure 3 and figure 4. The majority of their energy is derived from gravitational potential energy as opposed to nuclear sources within stars.  Only Radio galaxies are galaxies dominated by radio emissions from jets stemming from SMBHs. AGN are the small, dense and luminous components of the centers of galaxies as represented in Figure 3 and Figure 4. The majority of their energy is thought to be derived from gravitational potential energy and SMBH spin as opposed to nuclear sources within stars.  It was  in the late 1940s when  the connection between cosmic radio waves and synchrotron emission could be established.Synchrotron emissions of was established. Synchrotron emission in  AGN is due to the presence of magnetic fields. This emission is observable as polarized emission. Cosmic Astrophysical  objects emit intense radio waves through the synchrotron emission. It is widely held that radio sources in the cosmic universe Universe  emit by the synchrotron process, especially atthe  lower radio frequencies in the metre meter  and cm centimeter  wavelength range. (http://www.ugr.es/~battaner/escritos/granada_paper.pdf). The core of an AGN emits synchrotron radiation emitted through particle acceleration and collimation into a double lobed structure. These are typical traits of radio galaxies. AGN also have a pair of jets of material ejected from their core. The structure of a radio source is also determined by the interaction of its energetic jets with ionized gas which surround the host galaxy. (Krawczynski et al, 2013) also observes that the black holes in AGN accrete matter and convert the gravitational energy of the accreted matter (and possibly also the rotational energy of the black hole) into mechanical and electromagnetic energy. We also have that inside the accretion disk, a portion of the gravitational energy of the accreted material is converted to heat and electromagnetic radiation which is then radiated away by the accretion disk. The jets are formed from a portion of the material processed through the accretion disk which escapes the accretion system as collimated and uncollimated outflows. Jet plasma velocity can be denoted by v where v = β_jet c ≈ c ,and c represents the speed of light. Γ_j The bulk Lorentz factor of the plasma is given by Γ_(jet ) = (1-〖β_jet〗^2 )^(-1/2) . Emissions from the jets can be red or blue-shifted as a result of the relativistic Doppler factor δ_jet= 1/(Γ_j (1- β_jet⁡(cos⁡θ )))
