Abstract: We present GMRT multi-frequency radio observations of the centres of five Giant Low surface Brightness (LSB) galaxies. LSB galaxies have massive HI disks, are poor in star formation and are possibly the most dark matter dominated systems in our nearby universe. AGN have been detected at optical wavelengths but further studies at radio wavelengths have not been done before. We have conducted GMRT observations at 1.4 GHz and 610 MHz of five LSB galaxies that have prominent bulges and extended LSB disks. Our maps show that the emission is usually concentrated in the central region and is often associated with AGN activity and sometimes star formation as well. Compact cores and extended features resembling radio jets or lobes are seen in three galaxies while the remaining two galaxies have diffuse radio emission associated with the old stellar population in the bulge.
