ASTR 130     Introduction to Astronomy     3 Credit Hours

A one-term introduction for those interested in learning about the present state of knowledge of the Universe, its origin, evolution, organization, and ultimate fate. Exciting new discoveries concerning extrasolar planets, star birth, supermassive black holes, dark matter/dark energy, and cosmology are discussed. Two years of high school math or its equivalent recommended. Three hours lecture. (F, W, S).

ASTR 131     Introductory Astronomy Lab     1 Credit Hour

An introduction to some of the important observational techniques and analytical methods used by astronomers. Ground-based and satellite data will be used to reveal physical and chemical properties of the moon, planets, stars, and the Milky Way. Outdoor exercises involving telescopic observation of the sun, variable stars, nebulae, and external galaxies are also included. Constellation identification will be taught using off-campus planetarium facilities. Four hours laboratory. (F, S).

Prerequisite(s): ASTR 130* or PHYS 130

ASTR 133     The Search for Life in the Universe     4 Credit Hours

A one-semester course on the scientific search for life throughout the Universe. The range of environments hospitable for life form an organizing principle by which to examine several aspects of modern Astronomy including, but not limited to: habitats in the Solar System; physical constraints on life and unusual chemistry; the Search for Extraterrestrial Intelligence and the Fermi Paradox. Two years of high school math or its equivalent is recommended. Four hours lecture. (F, W).

ASTR 301     Astrophysical Concepts     4 Credit Hours

A one-semester course introducing the Physical concepts used in Modern Astrophysics, with an emphasis on the application of these ideas to Astrophysical objects. The course familiarizes the student with the Astronomical concepts and vocabulary used in other Astronomy courses at the 300-level and beyond. The course begins with an overview of Astronomical objects and terminology, before introducing conservation laws in Physics and their applications in Astronomy. Newtonian mechanics and gravity are then introduced and applied to various self-gravitating systems and scenarios. Electromagnetism, Quantum Mechanics and a small amount of Statistical Physics are covered at sufficient detail to understand the behavior of electromagnetic radiation and thermal emission. Special and General relativity are introduced from the point of view of understanding the behaviors of certain exotic objects in Astronomy. Common statistical distributions used in upper-level Astronomy courses are also introduced with an emphasis on application. Four hours lecture. (OC).

Prerequisite(s): (MATH 114 or MATH 116) and (PHYS 126 or PHYS 151)

Restriction(s):
Can enroll if Level is Graduate or Undergraduate
Can enroll if College is Engineering and Computer Science or Education, Health, and Human Services or Business or Arts, Sciences, and Letters

ASTR 330     The Cosmic Distance Scale     4 Credit Hours

An exploration of the cosmic distance ladder focusing on the systems and techniques that astronomers use in establishing the distances to celestial objects, from the very close (the size of the Earth), to the very far (the edge of the visible universe itself). Techniques covered will include, but are not limited to; naked eye methods for the Earth-Moon-Sun system; radar ranging for objects within the Solar System; trigonometric parallax methods; distance indicators using the interstellar medium; pulsating stars and other "standard candles"; methods based on the astrophysics of galaxies; Type Ia supernovae and related techniques; and methods based on gravitational wave astronomy. At each rung of the ladder, emphasis will be placed on the astrophysical principles and processes underlying the methodology being applied. This course includes an introduction to statistical techniques as applied in astronomical measurement, including a brief introduction to Bayesian techniques in astronomy. Four hours lecture. (OC).

Prerequisite(s): (MATH 113 or MATH 115) and (PHYS 126 or PHYS 151)

ASTR 361     Observational Techniques     4 Credit Hours

This course is designed to provide students with an understanding of some of the basic observational techniques use by astronomers in gathering and analyzing data from celestial objects. Practical experience in acquiring, displaying, and interpreting optical and radio observations using the University's 0.4-m telescope and 2.3-m radio dish will be emphasized. Topics will include astronomical coordinate system and timekeeping, telescope optics, the design and use of CCD detectors, fundamentals of multi-color photometry, an introduction to astronomical spectroscopy, and radio measurements of the Sun and interstellar hydrogen clouds at 21-cm wavelengths. (2 hours lecture, 6 hours laboratory) (S, OC).

Prerequisite(s): (ASTR 130 or PHYS 130) and (PHYS 126 or PHYS 151)

Prerequisite(s): ASTR 130 or PHYS 130

ASTR 421     Stellar Astrophysics     4 Credit Hours

An application of important physical principles to stars and star clusters. Topics will include gravitational collapse and star formation, radiative transfer and stellar atmospheres, nucleosynthesis and the structure of normal stars, degeneracy and the endpoints of stellar evolution, and general relativistic effects in the vicinity of black holes. Four hours lecture. (OC).

ASTR 445     Galaxies and Cosmology     4 Credit Hours

A course devoted to our current understanding of the composition, structure, and evolution of the universe based on general relativistic theory and astronomical observations of remote galaxies using both ground-and space-based technologies. Topics include observational characteristics, classification, kinematics and evolution of galaxies, quasars and active galactic nuclei, the cosmic microwave background radiation, concepts of general relativity, single-and multi-component models of the universe, dark matter and dark energy, and the orgin of the universe (the big bang, inflation and the creation of the first elements).
