In this thesis we will use large-area optical and radio surveys (SDSS and FIRST) are used to systematically measure the enhanced radio emission in merging galaxies in the low redshift Universe ($z < 0.4$). Through the use of statistical techniques on a catalogue of all the optically-selected SDSS quasar pairs for which there is a radio detection (in FIRST) within 3 arc seconds (which is roughly half the angular resolution of the radio maps in FIRST). The statistically analyzed data will be combined with a sample of "post-merger" (clearly disrupted, but individual) galaxies with the aim of investigating the nature of this enhanced emission as a function of galaxy separation.  The We look at the distribution of the  sample data with regards to their pair projected separation so as to give us an idea  of“post-merger” galaxies lists  theoptically-selected SDSS quasar pairs that are not detected in  the FIRST radio maps. In other words, for these pairs, no radio source was detected within 3 arc seconds level  of interaction between  the optical position. As non-radio-detected SDSS quasar quasars in our pairs. the relationship between this  pair images are stacked up (add) separation and  the radio maps of pair velocity offset as well as  the non-detections later on and get a statistical radio detection. We aim redshift are also analyzed so as to be able  to observe make inferences about merger events  and analyze these detections. AGN activity
