We present a comprehensive study of the stellar population and the interstellar medium in NGC 6822 using high-quality H I data (obtained with the Australia Telescope Compact Array) and optical broadband and narrowband data (obtained with Subaru and the Isaac Newton Telescope).

We find hitherto unknown H II regions in the...[Show more]
