The astrophysics concentration is designed for students interested in developing a background in the theoretical modeling and observational techniques of galactic and stellar astronomy, extragalactic astronomy and cosmology. Students will acquire the following abilities: to think critically about scientific problems, to reduce complex problems to their most important attributes, and to design experiments, observations and theoretical models to address those attributes. Students pursuing an astrophysics concentration are expected to have a strong background in physics and mathematics.



  • Students must complete a minimum of 20 credit hours including 12 of upper division hours for this concentration.
  • Students must take at least 12 of the 20 units at ASU.
  • All courses must be completed with a grade of “C” (2.00) or higher.
  • A minimum 6 upper division hours must be taken in courses offered by the College of Liberal Arts and Sciences.
  • All students will be required to meet with an academic advisor in the School of Earth and Space Exploration to declare the concentration and confirm that the requirements are being met.
  • Transfer course work must be evaluated by an advisor in the School of Earth and Space Exploration before it can be applied toward the concentration requirements.
