| Questions from "Appleby Galaxy Zoo Lab Project v.July 2010.doc" |
| #1. | | | | | | | | Average color index of spirals: |
| | | | | | | | | Average color index of ellipticals: |
| #2. | A color index of less than 0.45 is considered red. |
| | A color index greater than 0.45 is considered blue. |
| | | | | | | | | Which are redder: spirals or ellipticals?: |
| (#3.) | Choose one of your galaxies above and copy-paste its spectrum to a word document. |
| | Use circles to identify at least 5 absorption lines ("dips"). |
| | Use circles to identify at least 1 emission line ("peak"). |
| | Hint: See "NGC 3310 Example spectra.doc" |
| #4. | | | | | | | | How do elliptical and spiral spectra differ?: |
| #5. | | | | | | | | How do the quantity of emission lines differ between galaxy types?: |
