ZAMRI ZAINAL ABIDIN ABSTRACT The use of small radio telescope could not be dismissed in the search of dark matter. Although the capability of this instrument is limited, the information that we obtain from the observation of small radio telescope is vital for finding the total hydrogen mass of a galaxy cluster, MHI. MHI value is then can be interpreted as the total baryonic component that contain in the cluster and lead to the identification of major component of mass that drives the cluster to be in their equilibrium state (the summation of all the galaxies in the cluster and intracluster medium does not sufficient to supply gravitational potential energy that keep all the galaxies bounded together). According to Battye et al., 2004, the synthesized beam size produced by the telescope depends on the collecting area (or size) of the telescope allowed us to attain MHI for the cluster covered by the beam pattern of the telescopes instead of MHI for the individual galaxies in the cluster – which makes use of much bigger telescope to increase the sensitivity. Preliminary data by invoking this method of observation showed that this method is applicable in the searching of dark matter influence in cluster.
