Attendance (via Zoom) is strongly encouraged but not required. Part of your grade is participation-based, which requires you to be virtually present during lectures. However, given the possibility of unforeseen technical challenges, occasional absences are acceptable. All lectures will be recorded and posted to Canvas for later review.
Knowledge and navigation of Canvas and Zoom is critical to access all features and resources of this course. Lectures will be conducted via Zoom during class times, and participation is expected. Exams will also be conducted remotely through Zoom, and exams will be submitted electronically at the end of the time allotted through Canvas (in the same manner as HWs). Be aware that a sufficiently high bandwidth and stable internet connection will be necessary during lectures and exams.
In the event a student cannot attend a lecture, either in person or online, videos of the lecture will be uploaded to Canvas for later viewing. Other material will also be made available on Canvas, including reminders and announcements. Please set up Canvas to notify you when material is added; it is assumed that students will see any Announcements made by the instructor within 24 hours of them being posted.
For technical assistance, review the Canvas Getting Started Guide for Students and/or contact TLT, Knowledge Commons, etc.
Students must self-report if they test positive for COVID-19 via coronavirus.utah.edu.
Remember to maintain social distancing at all times. Based on CDC guidelines, the university requires everyone to wear face coverings in shared public spaces on campus.
As an upper-level undergraduate introduction to cosmology, this course will discuss the standard big bang theory of the universe and introduce the current scenario for the origin and growth of large-scale structures. After taking the course, students are expected to have a basic knowledge of modern cosmology and be prepared for further study.
As stated in the textbook, the course is intended to be taken primarily by juniors and seniors in physics and astronomy. It requires the students to have a good background in physics, with a basic understanding of electrodynamics, statistical mechanics, classical dynamics, and quantum physics. For mathematics, a good background in integral and differential calculus is necessary. No prior knowledge of general relativity is assumed, and we will introduce the minimal amount of materials as needed.
The course explores the theory and observational evidence of modern cosmology. The course will talk about basic equations describing the universe, the expansion and age of the universe, dark matter and dark energy, the thermal history of the universe, the origin of the light elements, and the blackbody spectra of the cosmic microwave background. The course will also briefly cover topics about the origin of structures in the universe, including growth of density perturbations and cosmological inflation.
The following sections detail the structure, requirements, and expectations of the course. The instructor reserves the right to modify any of the policies currently described here, but will endeavor to hew closely to the syllabus as outlined on the first day of class, and any subsequent changes will be communicated clearly to the class.
Chapters from the textbook should be read prior to the week the topic is discussed. For example, Chapter 3 should be read before Jan. 26th and Chapter 2 read before Jan. 21st. Part of the final grade will include in-class participation via answering questions and involvement in discussions. Therefore, regular class attendance is expected, but 100% attendance is not necessary to receive full participation credit.
Problem sets covering material from the textbook and in class will be due every Thursday at the start of class except for midterm exam days. Each assignment will be posted online by 10:45am the previous Thursday if not before. There will be 11 total homework assignments; only 10 will count toward the final grade (with the lowest score dropped). Solutions will be posted, along with graded homeworks, on the following Tuesday (on a best-effort basis). Two late assignments will be accepted if submitted by the start of the following Tuesday class, before solution sets are provided. One additional late assignment will be accepted a week later than the regular late acceptance date (2nd Tuesday after an assignment is due). Please notify the instructor on the due date via email that the HW will be late and how late it will be. NOTE: The last HW assignment, HW11, is not eligible for late submission.
All exams will be open book/open note and cover all material up to that point in the course, although Midterm 2 will emphasize new material covered after Midterm 1. Both midterms will take place at the regular class time from 10:45am-12:05pm. The Final Exam will be comprehensive, but somewhat emphasize new material. For dates, see the Course Schedule above.
Each student will choose a topic on observational constraints on cosmology, read relevant research papers, and give a presentation. The presentation topic for each students will be decided around early March. Details to be announced. A list of possible topics will be posted online.
Grades are determined from homework, class participation, exams, and student presentations according to the following weights:
Ultimately, grades may be assigned on a curve, but only in a favorable direction from a baseline distribution. You may calculate your final grade based on past and extrapolated grades to estimate your minimum actual final grade. The magnitude/formula of the curve is determined at the discretion of the instructor. The baseline grade distribution will assume:
Cheating (including copying homework from any sources) will not be tolerated, and zero credit will be given on the assignment or exam for all parties involved.
Title IX makes it clear that violence and harassment based on sex and gender (which Includes sexual orientation and gender identity/expression) is a civil rights offense subject to the same kinds of accountability and the same kinds of support applied to offenses against other protected categories such as race, national origin, color, religion, age, status as a person with a disability, veteran’s status, or genetic information. If you or someone you know has been harassed or assaulted, you are encouraged to report it to the Title IX Coordinator in the Office of Equal Opportunity and Affirmative Action, 135 Park Building, 801-581-8365, or the Office of the Dean of Students, 270 Union Building, 801-581-7066.
