In this activity, you will draw Sersic Profiles. On a single plot, draw the surface brightness profiles, I(r)/I0, for each of an elliptical galaxy and the disk of a spiral galaxy. Use the values you found in Problems 1 and 2 on the Module 8 problem set to label specific points on each curve (you can use the values from your final submission). Be sure to label your axes and include a legend identifying each curve. The x-axis should range from r=0 to r=20r0. Note: Use of plotting software (e.g. Excel, Matlab, Mathematica, python) is required. Upon submission you will automatically receive full credit. However, plots and your answers will be reviewed and points will be deducted for inaccurate plots, and/or plots missing any of the key components
