HII Regions in NGC 2903

Forums Spectroscopy NGC 2903 HII Regions in NGC 2903

Hi Alun,

That is an interesting spectrum. The hydrogen emission lines that you have picked up will be from HII regions within NGC 2903. Doing a little digging around I see that this galaxy has a high star formation rate. So it makes sense that it has a lot of bright clouds of hydrogen which will be forming stars.

Best wishes,
