The figure below shows the spectra of two galaxies A and B. Please can i get help with this questions below: 1. Which of these galaxies has ongoing star formation? How can you tell? 2. One of these galaxies has Hubble type E3 while the other is SBb. Which is which? What does the 3 in E3 tell you about the galaxy? What does the SB in SBb tell you about the galaxy? 3. What effects would dust have on the two spectra?
