The temperature fluctuations of the cosmic microwave background (CMB), as seen by NASA's WMAP satellite.

Summary

Cosmology, the study of the Universe, its birth and evolution, is currently experiencing a tremendous renaissance, mostly due to the plethora of new observations such as the observations of the Cosmic Microwave Background (CMB) by NASA's WMAP satellite. This introduction to modern cosmology discusses the big bang, the expanding Universe and the basic cosmological parameters describing it, the dynamics of our Universe, dominated by some unspecified dark matter and dark energy, arguments for an early inflationary period, the formation of light elements in the early universe, and the wealth of information we extract from measurements of the CMB.

By the time the semester is over, the students will have an up to date knowledge of the evolving state of affairs in cosmology, of the things we are pretty sure we understand, as well as of the open issues that arguably make cosmology the most exiting area of physics and astronomy. We will make use of the most basic notions of general relativity and elementary particle physics, and we will focus our efforts in understanding the concepts of cosmology, their observational foundation, their range of applicability and their limitations. Beyond the required text "Introduction to Cosmology" by Barbara Ryden, articles from journals such as "Scientific American" and "Science", and specialized astrophysics journals, as well as of cosmology web pages from various institutes and universities.

    Academic Integrity
    By enrolling in this course, each student assumes the responsibilities of an active participant in UMBC's scholarly community in which everyone's academic work and behavior are held to the highest standards of honesty. Cheating, fabrication, plagiarism, and helping others to commit these acts are all forms of academic dishonesty, and they are wrong. Academic misconduct could result in disciplinary action that may include, but is not limited to, suspension or dismissal. To read the full Student Academic Conduct Policy, consult the UMBC Student Handbook, the Faculty Handbook, or the UMBC Policies section of the UMBC Directory.
