The Department of Astronomy offers two undergraduate degrees, a Bachelor of Science and a Bachelor of Arts. The BS provides a rigorous sequence of subject-specific courses, while the BA degree provides somewhat more flexibility in the choice of courses. The department also offers a minor in astronomy.

The curriculum emphasizes a broad and substantial education in astronomy, physics, and mathematics. A faculty actively engaged in research provides first-rate instruction and opportunities for undergraduate involvement in research.

A bachelor’s degree in astronomy can prepare students for graduate study in astronomy (about 50% of our graduates take this path), but those who seek employment in other fields can fill the same jobs as physics and computer science majors.

The department offers a graduate program leading to the degree of Doctor of Philosophy in astronomy. Current research provides opportunities in observational and theoretical studies of galaxy formation and evolution, galaxy cluster evolution, astronomical instrumentation, and cosmology.

### Facilities

The Department of Astronomy operates the Kitt Peak Station of the Warner and Swasey Observatory near Tucson, Ariz., home of the Burrell Schmidt telescope. This telescope is used for surveys and ultra-deep imaging with a large format CCD. Observatory operations are managed by Dr. Paul Harding and Charles Knox. Dr. Harding also leads departmental efforts in instrumentation for the Observatory.

On the Case Western Reserve campus, a 9.5-inch refractor permanently mounted on the roof of the A. W. Smith Building is available for use by students. The department also houses a research and instruction computer laboratory and has access to the university's high-performance computing cluster.

## Graduate Program

The PhD degree in astronomy is granted to those students who have shown an extensive knowledge of advanced astronomy and the ability to do original research. The student is required to pass a general qualifying examination in astronomy, usually taken at the end of the second year. The student must then prepare a dissertation based on the results of independent research. A PhD candidate must also satisfy the general requirements of the School of Graduate Studies.

Full-time graduate students who maintain satisfactory academic performance while pursuing the PhD degree in astronomy normally receive a stipend for teaching and/or research, which includes full tuition and a monthly amount sufficient to cover living expenses.

**ASTR 151. Doing Astronomy. 1 Unit.**

This course is intended to introduce students to how astronomy is done. The course will focus on the astronomical research process, the scientific community, and on career paths in astronomy. Course activities will include readings and class discussions focusing on various topics in modern astronomy, including ongoing research activity in the department. This course is largely intended for first- and second-year students considering majoring or minoring in astronomy, or pursuing a career in astronomy.
Prereq: First- or second-year academic standing.

**ASTR 221. Stars and Planets. 3 Units.**

Stellar structure and energy production. Formation and evolution of stars. Supernovae, neutron stars, and black holes. Star clusters. Planetary systems and the detection of extrasolar planets. The application of physical laws to the study of the universe.

The Milky Way Galaxy. Structure, dynamics, and evolution of galaxies. Galaxy clusters and large scale structure of the Universe. Physical cosmology and the Big Bang. Evolution of the Universe.
Prereq: ASTR 221.

**ASTR 306. Astronomical Techniques. 3 Units.**

This course covers the techniques astronomers use to conduct research, including observations using ground-and space-based telescopes, computer simulations and other numerical methods, and statistical data mining of large on-line astronomical datasets.
Offered as ASTR 306 and ASTR 406. Counts as SAGES Departmental Seminar.

**ASTR 311. Stellar Physics. 3 Units.**

Radiative transfer, atomic and molecular opacities, and the observable properties of stars. Stellar interiors, nuclear processes, and energy generation. The evolution of stars of varying mass and production of the elements within supernovae explosions.

Prereq: ASTR 222.

**ASTR 323. The Local Universe. 3 Units.**

The Milky Way Galaxy. Galaxy populations. Quantitative structure and dynamics of galaxies. The interstellar media of galaxies. Dark matter and stellar populations. The Local Group and Virgo cluster.
Offered as ASTR 323 and ASTR 423.
Prereq: ASTR 222.

**ASTR 328. Cosmology and the Structure of the Universe. 3 Units.**

Offered as ASTR 328, PHYS 328, ASTR 428, and PHYS 428.
Prereq: ASTR 222.

**ASTR 333. Dark Matter. 3 Units.**

This course will systematically explore the evidence for dark matter in the universe. Necessary physical theory and astronomical concepts will be developed as appropriate. Topics to be covered include gravitational dynamics, gravitational lensing, and hydrostatic equilibrium as probes of the gravitational potentials of extragalactic systems. Examples include the rotation curves of spiral galaxies, the Oort discrepancy in the local Galactic disk, the dynamics of pressure supported dwarf and giant elliptical galaxies, and the Local Group timing problem. In clusters of galaxies, the mass discrepancy is illustrated separately by measured velocity dispersions, the hydrostatic equilibrium of the hot intracluster medium, and both strong and weak gravitational lensing. On cosmic scales, the course will address evidence from the gravitating and baryonic mass content of the universe, the growth of large scale structure from the initially smooth cosmic microwave background, and the existence of large voids and large scale bulk flows. The course will describe the various dark matter halo models commonly employed and introduce the techniques of mass modeling. We will examine hypotheses for the nature of dark matter, both baryonic and non-baryonic, and discuss strategies for experimental detection of plausible dark matter candidates. Theories that seek to explain the observed mass discrepancies by means of modifying the Law of Gravity rather than invoking dark matter will be explored.
Offered as ASTR 333 and ASTR 433.
Prereq: PHYS 310 or requisites not met permission.
