Radio astronomy is a new scientific research field in Southeast Asia. University Malaya is pioneering this field in this region with University Malaya Radio Telescope (UMRT-2), which is located on the department of physics, University of Malaya to detect neutral hydrogen emission line. In this paper, we observe Doppler shift of 1420 MHz for different radio sources to determine their dynamics. We also analyze radio spectra of different radio sources for these purposes including Coma Cluster roughly estimate the dark matter constant in it. We also investigated the observation time effort of Coma Cluster spectra detection we found the dark matter mass to be significantly too high, but we successfully concluded that longer observation time improves spectrum detection of weak radio sources.
