Student Handbook

Work with world-class faculty, including theorists, observers and instrumentalists, on NASA- and NSF-funded projects to discover new planets, trace the evolution of stars and galaxies, explore the origin and development of the universe, build spaceflight hardware and design instruments for telescopes and satellites.

Program Description

Degree Awarded: PHD Astrophysics

The PhD program in astrophysics develops creative scholarship in students and prepares them for professional careers in astrophysics, astronomy or related fields.

Students in this program take graduate-level courses in stars and interstellar media, galaxies and cosmology; obtain quantitative skills through analysis and modelling; may have observing opportunities through regional and international telescope observatories; and conduct independent, fundamental astrophysical research. Graduate students work closely with a research advisor on a wide range of topics including theoretical physics, cosmology, galaxy dynamics, stellar evolution, exoplanets, and the development and building of instrumentation.

Graduate students in astrophysics become leaders in observational and theoretical research. They participate in NASA- and NSF-funded space missions and study topics such as how stars are born and die, how galaxies interact and evolve, and how the universe changed as it developed from its earliest beginnings.

The program's world-class faculty have research expertise across the full breadth of astrophysics including the solar system, stars and galaxies from the Milky Way and the most distant galaxies in the universe. Current ASU research applies both computational and observational approaches to the exploration of a range of topics such as fundamental cosmology and whether there is life on exoplanets.

Career Opportunities

Professionals with expertise in astrophysics are in high demand across all sectors and industries, including remote sensing, data science, instrument building, computational science, defense industries and scientific research. Coding and numerical modeling skills translate across many domains, even beyond astrophysics. Skills in the measurement and analysis of data related to the physics, chemistry and structure of the universe and exoplanetary systems are valuable to businesses and institutions relying on data-driven strategies to explore beyond the Earth and solar system.

A doctoral degree in astrophysics is required for some careers in post-secondary education and research.

Career examples include:

  • astrophysics professor
  • data scientist
  • instrument builder
  • project manager
  • research astronomer
  • telescope operator

Concurrent degree programs are specially designed academic programs which provide high-achieving undergraduate students the opportunity to complete two distinct but complementary bachelor degrees at the same time. Students must meet minimum admissions standards for both programs and be accepted individually by both colleges offering the concurrent program.
Students pursuing concurrent degrees earn two distinct degrees and receive two diplomas. ASU offers students two ways to earn concurrent degrees: by choosing a predetermined combination or creating their own combination. Predetermined combinations have a single admissions application and one easy to follow major map. To add a concurrent degree to your existing degree, work with your academic advisor. Either way, concurrent degrees allow students to pursue their own personal or professional interests.
Accelerated bachelor's and master's degree programs are designed for high-achieving undergraduate students who want the opportunity to combine undergraduate coursework with graduate coursework to accelerate completion of their master's degree. These programs feature the same high-quality curriculum taught by ASU's world-renowned faculty.
ASU students may accelerate their studies by earning a bachelor's and a master's degree in as little as five years (for some programs) or by earning a bachelor's degree in 2.5 or 3 years.

These programs, featuring the same high-quality curriculum taught by ASU's world-renowned faculty, allow students to obtain both a bachelor's and a master's degree in as little as five years.

Accelerated bachelor's degree programs allow students to choose either a 2.5- or a 3-year path while participating in the same high-quality educational experience of a 4-year option. Students can opt to fast-track their studies after acceptance into a participating program by connecting with their academic advisor.
This is only the first required math course. This program may contain additional math courses; See Major Map for details.

A rolling deadline means that applications will continue to be reviewed on a regular basis until the semester begins. International students should be mindful of visa deadlines to ensure there is time to produce necessary visa documents. Applicants are encouraged to complete and submit application materials as soon as possible for consideration.
A final deadline means that all applications and application materials must be received by Graduate Admissions by the deadline date. Applications that are incomplete may not be considered after the final deadline. Applications that are submitted past the final deadline may not be considered.
A priority deadline means that applications submitted and completed before the priority deadline will receive priority consideration. Applications submitted after the priority deadlines will be reviewed in the order in which they were completed and on a space available basis. An application is complete after all materials are received by Graduate Admissions.
