MODELING SOME INTERGALACTIC RADIO COMPONENTS’ AND COSMIC EXPANSIONS

Abstract

Analytical and statistical methods are used to find a mathematical model that plausibly may connect cosmic 
expansion, and expansions of some intergalactic radio components (such as the extragalactic radio jets and 
lobes of some radio galaxies). These are done by carrying out some regression analyses on some measurable 
parameters of the more extended radio galaxies, as well as, on their more compact counterparts. Results of 
the size/redshift data for the more extended doubles indicate that these sources expand in size as cosmic 
expansion advances with time.
