Abstract

In this paper we discuss our multifrequency radio continuum and Hi observations of bulge dominated low surface brightness (LSB) galaxies made using the Giant Metrewave Radio Telescope. We present radio maps of five LSB galaxies which have compact radio cores indicative of AGN activity in their nucleus. We discuss the AGN in LSBs, their Hi content and the influence of the environment on the evolution of these galaxies.
