To appreciate that some galaxies emit far more energy at some wavelengths that can be explained simply in terms of ‘starlight’.. To recall the types of active galaxies.. To show an understanding of the mechanism for producing large quantities of radiation from active galaxies.. David Cohen. Swarthmore College. If we understand the physical connection between magnetic fields in massive stars and X-rays, we could use X-ray observations to identify magnetic massive stars.. e.g. Which of the stars in this Chandra X-ray image of the Orion Nebula Cluster are massive magnetic stars? .

I will add 5 points on your final exam if you complete the evaluation.. Today’s model for the formation of the Milky Way and other galaxies. Most of the power of galaxies come from the stars.
