#### ASTR 106. Introduction to Astronomy/Lab.

How can we use light to learn about the universe? How can we measure the properties of planets, stars, and galaxies? How can we explore our cosmic origins and the history of the universe? This course provides an introduction to modern astronomy with an emphasis on how we know what we know. Enrollment limited to 84. (Community-Engaged Learning.) Normally offered every year.

#### ASTR 201. Introduction to Stellar and Planetary Astrophysics.

An introduction to stellar and planetary astrophysics, focusing on the basic physics required to understand and interpret astronomical observations of stars and planets. Building on a foundation of the introductory physics sequence, this course explores the consequences of Newtonian gravity and few-body dynamics, hydrostatic balance, nuclear reactions, and radiative transfer for the structure and evolution of stellar and planetary systems. Prerequisite(s): PHYS 107 and 108. [Q] [S] A. Diamond-Stanic, J. Oishi.Concentrations

#### ASTR 202. Galaxies and Cosmology.

An introduction to the astrophysics of galaxies and cosmology with an emphasis on the physical principles required to understand and interpret astronomical observations. Building on a foundation of the introductory physics sequence, this course explores properties of the Milky Way Galaxy, galaxy formation and evolution, the interstellar and intergalactic medium, dark matter and dark energy, the expansion history of the universe, and modern cosmology.

#### AT/PH 336. General Relativity.

General Relativity is a well-tested physical theory first formulated by Albert Einstein, which intricately links gravity to geometry. Course topics include Special Relativity; tensors; geodesics; curvature; and Einstein's field equations and solutions, including applications to black holes, gravitational waves, and cosmology. Additional topics may include experimental tests of General Relativity, the Einstein-Hilbert Action, quantum gravity, and alternative theories of gravity. Mathematical concepts are introduced as needed, but prior experience with linear algebra and differential equations is assumed. Recommended background: PHYS 422. Prerequisite(s): PHYS 108, 222, and 301. [Q] [S] Staff.Concentrations
