Textbooks

There is one required textbook for this course:

• Horvath (2022), High-Energy Astrophysics: A Primer (ISBN-13 9780521674423 for paperback)

Overview

Here's the official description from the course catalog:

Prerequisite(s): 01:750:342 or (361 and 385-386)

Radiation and scattering processes in plasma. Detection and X- and gamma-rays. Supernovae and remnants, pulsars. Gamma-ray bursts. Accretion disks and binary star outbursts. Quasars and active galactic nuclei. Cosmic rays.

I plan to broaden this list of topics to include important recent discoveries (e.g., studies of black holes using gravitational waves and very long baseline interferometry), and in general, subjects that are important to areas of current research in Galactic and extragalactic astrophysics and cosmology.

Schedule

Both the sequence of lectures and the assignment due dates are preliminary at this point; I will update them as needed during the course of the semester.

I will include in the schedule the dates of any local talks that are relevant to the subject matter of this course. Attendance is encouraged but not required!

Grading

Your course grade will be based on a weighted combination of four elements:

• homework assignments (50%)
• midterm exam (25%)
• final project (25%)

Homework assignments will generally be made available on Thursday and submitted (by emailed or uploaded PDF before 11:59pm) the following Thursday. They will include straightforward examples or extensions of material discussed in lecture, and more involved applications to areas of current research, which may encompass some computational work (especially later in the semester).

The midterm exam will be in class on TBD.

The final project will include an oral presentation and a written paper on a scientific or technical topic relevant to high-energy astrophysics. The paper should be written in LaTeX. More information will be provided about this assignment as the semester progresses.

Other items

• Absences
  I will have to miss two of our regularly scheduled classes, which will be taughe by guest lecturers in my absence. If you need to miss a class for some reason, please file a report at this website. There will be no direct penalty to your grade for missing class; however, since I will only be posting slides and equation sheets to the course website, you will not have the full context of the lecture, and you may need to rely on your classmates' notes to fill any gaps.
• Late assignments
  Unless you request advance permission and I grant it to you, I will start docking points at a rate of 10% off the top per day for each assignment.
• Collaboration policy
  On homework assignments, you should first try every exercise yourself before discussing it with others. If you get stuck (or finish and would like to compare answers), you may discuss exercises with other students in the course and/or me, but you should always write up your own solutions and indicate on your solutions whom you collaborated with. You may consult books and published papers, but not old solution sets from previous offerings of this course or similar courses elsewhere.
• Students with disabilities
  If you have a disability, let me know early in the semester so that we can make the necessary arrangements for you to have a successful learning experience. Please consult this web page for more details.
