Radio Imaging With SWAN
The Indian SWAN (Sky Watch Array Network) is a radio interferometric array presently located at Gauribidanur, near Bengaluru and operated by the Raman Research Institute. The primary motive behind the SWAN initiative is to provide much-needed exposure to research in radio astronomy to undergraduates interested in this field. At the same time, the SWAN is expected to increase Indian observing capabilities at low radio frequencies significantly. This article introduces imaging in radio astronomy and the corresponding data analysis techniques I learned while being associated with the SWAN project.
