ASTR 3830 -- Astrophysics-2

PROFESSOR:  Michael Shull (Office: Duane D-235)

TEACHING ASSISTANT:   None (we may have a grader)

TIME AND PLACE:   Lectures: MWF (10:00-10:50 am) in Duane G-131.  

COURSE HOME PAGE:  http://casa.colorado.edu/~mshull/astrophysics2-2013/  

GOALS OF THIS COURSE:   This class offers an introduction to the astrophysics of galaxies, quasars, and other extragalactic objects. This is the second semester of a two-semester astrophysics sequence, intended primarily for majors in Astrophysics, Physics, or other mathematics/science disciplines. Students are presumed to have the required mathematical and physics background (Third-semester Calculus and Physics). The overall goal is to familiarize you with current astronomical observations and the physical processes that govern galaxies, quasars, clusters, black holes, galaxy formation, and cosmology. I encourage regular class attendance and student engagement. I will hand out regular homework sets (50% of total grade). It will be in your interest to attend class regularly, to keep up with lecture material and reading. I will base 10% of the total grade on the effectiveness of your class participation.

The major topics to be covered in ASTR 3830 include:  

  • Review: Stellar Structure and Evolution
  • Review: Stellar Death and Endpoints (White Dwarfs, Neutron Stars, Black Holes)
  • Star Formation, Gaseous Nebulae, Interstellar Medium
  • The Milky Way Galaxy (structure, content, stellar orbits, dynamics)
  • External Galaxies (types, dynamics, structure, formation, evolution)
  • Clusters of Galaxies and Large-Scale Structure of Universe
  • Quasars and Super-massive Black Holes
  • The Expansion of the Universe and Big Bang Theory
  • Observational Cosmology (confronting theory with evidence)
  • Matter, Radiation, Galaxies in the Early Universe
  • Dark Matter, Dark Energy, and the Future of the Universe
TEXTBOOKS:   In this class, we will continue with the textbook from ASTR 3730. We will cover Chapters 24-30, with an in-depth revisit of Chapter 17 (General Relativity and Black Holes) and review of star formation, stellar evolution and collapsed-objects (WD, NS, BH) in Chapters 10, 12, 15, 16.

  • (1) Required - (Carroll & Ostlie) - "An Introduction to Modern Astrophysics"

OTHER READING:   At various times throughout the term, I will provide required supplementary readings In class, I sometimes introduce "Science News" headlines on astronomical discoveries relevant to the course. You are also encouraged to bring in astronomy news stories if they seem interesting. I am happy to spend a few minutes each class talking about these contemporary events.

For those of you who wish to read about Cosmology in more detail, here is a useful link to a Cosmology Tutorial, a Web-Tutorial, written by Ned Wright of UCLA, complete with Frequently Asked Questions, News of the Universe, even sections on "Cosmology and Religion" and "Cosmology and Art".

PREREQUISITES: First-semester Astrophysics-1 (ASTR 3730), Third-semester Calculus (MATH 2400 or APPM 2350), and Third-semester Physics (PHYS 2130 or PHYS 2170)  

MATHEMATICAL SKILLS REQUIRED:   Calculus through third-semester implies familiarity with multi-variable calculus and vector calculus (divergence, curl). You will need these tools in some of the course material dealing with gravitational potential theory, electromagnetic theory, and radiation processes.

20% - Final Examination (Monday May 6, from 4:30-7:00 pm)   
10% - Effectiveness of your Class Participation

EXAMS: Tests will comprise 40% of the total grade: 20% (final exam) and 20% (your two best scores on the 3 mid-course exams). The three mid-course exams are Feb 20, Mar 18, and Apr 17. No make-ups; I will drop your lowest score of the three mid-course tests.  

HOMEWORK: There will be regular homework over the semester, counting for 50% of your total grade.  These assignments should be turned in during class (no e-mail) or placed in my departmental box on the due-date.  

FINAL EXAM:  The final exam will be on Monday May 6 (4:30 - 7:00 pm)   in Duane G-131. The test will be cumulative (based on the entire course). It will be similar in form to the other exams, but may include a few short essay questions. Check your final exam schedule. If you have three or more finals scheduled for May 6, please talk to me or send email to: michael.shull@colorado.edu  before Monday Feb 18th regarding the other finals you will be taking that day. Don't plan on leaving Boulder before May 6.

TRACKING YOUR GRADES: If you have any questions about your grades, please see me during office hours, or make an appointment.

INCOMPLETES: The College of Arts and Sciences has strict rules about "Incomplete" grades. I can give a grade of "Incomplete" only in case of an emergency beyond your control, and I must have written documentation. Moreover, your current grade must be passing at the time the emergency occurs.  

DISABILITIES: If you qualify for accommodations because of a disability, please submit to me a letter from Disability Services in a timely manner so that your needs may be addressed. Disability Services determines accommodations based on documented disabilities.   Contact: 303-492-8671 or by e-mail at dsinfo@colorado.edu. If you have a temporary medical condition or injury, please looks at "Temporary Injuries" under Quick Links at http://www.Colorado.EDU/disabilityservices and discuss your needs with your professor.

RELIGIOUS OBSERVANCE: Campus policy regarding religious observances requires that faculty make every effort to deal reasonably and fairly with all students who, because of religious obligations, have conflicts with scheduled exams, assignments or required attendance. Please see me early in the term to discuss any such conflicts. See full details at http://www.colorado.edu/policies/fac_relig.html.

CU HONOR CODE:
I expect all CU students to be aware of and follow the CU Honor Code as well as the CU Policy on Classroom and Course-Related behavior. Please come to class on time, and do not disrupt the attention of other students by conversation or leaving the classroom early with excess noise. Students and faculty each have responsibility for maintaining an appropriate learning environment. Those who fail to adhere to such behavioral standards may be subject to discipline. Professional courtesy and sensitivity are especially important with respect to individuals and topics dealing with differences of race, culture, religion, politics, sexual orientation, gender, gender variance, and nationalities. All students of the University of Colorado at Boulder are responsible for knowing and adhering to the academic integrity policy of this institution. Violations of this policy may include: cheating, plagiarism, aid of academic dishonesty, fabrication, lying, bribery, and threatening behavior.   All incidents of academic misconduct will be reported to the Honor Code Council (honor@colorado.edu; 303-725-2273). Students who are found to be in violation of the academic integrity policy will be subject to both academic sanctions from the faculty member and non-academic sanctions (including but not limited to university probation, suspension, or expulsion). Other information on the Honor Code can be found at http://www.colorado.edu/policies/honor.html 

NOTE: It's fine to help each other with homework; I encourage you to do so, and will also offer help during office hours. But simply copying other people's work without trying to understand it is cheating. The reason homework is assigned is for YOU to learn what you need for the course, and what you hand in should show us that YOU personally understand it.  If we find two or more homework assignments with answers that are so exactly alike that we suspect unthinking copying, we will split the credit for the work equally between each submitter (note that this means you also must be careful not to let others copy your work!).  If you worked with another student on homework assignments to the point where you suspect that you may have very similar answers, please write so on the front page of the homework assignment (e.g. "I collaborated with: Albert Einstein, Isaac Newton and Stephen Hawking on this assignment." )  Similarly, we'd like to know if you received help with a given problem from a tutor- this will not change your grade, but will allow us to track which questions are challenging students the most.

If you copy text or other information from any source for any reason, you must also include a citation to that source (for example,  Bennett et al., "The Cosmic Perspective,"  p. 461;   or    From " Astronomy Picture of the Day Website, http://antwrp.gsfc.nasa.gov/apod/astropix.html,   Authors & editors: Robert Nemiroff (MTU) & Jerry Bonnell (USRA).) Doing this will keep you from plagiarizing, and will allow us to appreciate your good scholarship.

If a student is caught cheating on a quiz or exam, the minimum penalty will be a grade of F on that exam and the maximum will be an F in the course.   University policy requires us to report any cheating incident to the Honors Council.  

PERSONAL BEHAVIOR (University Policy):
Students and faculty each have responsibility for maintaining an appropriate learning environment. Students who fail to adhere to such behavioral standards may be subject to discipline. Faculty have the professional responsibility to treat all students with understanding, dignity and respect, to guide classroom discussion and to set reasonable limits on the manner in which they and their students express opinions. Professional courtesy and sensitivity are especially important with respect to individuals and topics dealing with differences of race, culture, religion, politics, sexual orientation, gender variance, and nationalities.  Class rosters are provided to the instructor with the student's legal name. I will gladly honor your request to address you by an alternate name or gender pronoun. Please advise me of this preference early in the semester so that I may make appropriate changes to my records.  See policies at
