Recognizing+different+types+of+spectra

Back to What tools do you need to study AGN?

Now that you know what spectra is we can start to apply that knowledge.

The first thing is to find how to differentiate different spectra. As we found out in the spectra page, different chemicals produce different emission lines. On the picture above there are some emission lines for different chemicals as well as our sun. From the emission lines we know we can find out what the chemical is and/or what something is made of. On this we can see the emission lines in on a graph. The peaks are the emission lines that are the most prominent and from that we can differentiate different chemicals, stars, and galaxies.

Now that we know how to differentiate emission spectra we can go onto differentiating spectra of entire galaxies in Recognizing different types of AGN galaxies
