Low frequency observations of high redshift galaxies

Abstract

Although our understanding of the evolution of the stellar population of galaxies has improved dramatically in the recent past, our understanding of the evolution of the neutral atomic gas content in star forming galaxies remains limited. This is largely because of the sensitivity limit of the current generation of radio telescopes. The scenario is changing however, both because of new instrumentation and deeper integrations with the existing telescopes. In this article, I review the current status of, and future prospects for, low radio frequency observations of gas in high redshift galaxies. The indications are that the community is moving from an era of fasting to an epoch of feasting.
