    Abstract: Analytical and statistical methods,with some plausible assumptions, have been used in this work to show presence of dense medium around compact steep-spectrum sources in our sample. This is done by carrying out regression analyses using our estimated jet’s internal densities (n_j ) and some other source parameters for possible deductions. Results i... Show More

    Abstract: The nature of the universe is such the speed of light in a homogeneous medium is a constant that is determined by the permittivity and permeability of the medium including a vacuum; a path of light appears to depend on the observer’s frame of reference. This led to believe that the time depends on the observer’s frame of reference, which is an inhe... Show More
