The panel below shows an overlay of individual spectra of the nitrogen line, all taken simultaneously with the PACS spectrometer, on the dust continuum as observed with the PACS photometer.
The width of these spectral lines can be used to determine the speed of the gas.
These very first data are of unprecedented sensitivity, accurately tracing the physical conditions in cold and warm gas. The next step is to supplement these first results with data from other atomic species to build up a picture of how the gaseous and dusty structures are shaped further out.
