AST1440 -- Radiation (Spring 2018)


Welcome to the Light.

Contact Information:

Instructor: Prof. Yanqin Wu

Lectures: Tuesday 2-3:30pm

                Thursday 2-3:30pm

Room: Bancroft 215

Email: wu@astro
Office: MP1210, x8-5633

Short Presentations:

1) Each student is slated to present for 10 minutes, in the beginning of each lecture. See the calendar for arrangement. This is on a pre-assigned topic that is closely related to the lecture material and should be considered as mini-lectures.

2) During the reading week, we will hold two dedicated sessions of presentations, with each student giving a presentation on a pre-assigned topic. 10 minutes (include questions).

Long Presentations:

"free subject"  either based on real examples of radiative transfer, or detailed discussion of a process not covered in class. 20 minutes each + 5 minutes of question/discussion.

Do not attempt to be overly mathematical, but try to illuminate the physics for your fellow students. Always, give concrete examples. And the best presentations involve order-of-magnitude estimates.

Send me title of your long presentation by Monday Mar. 26th. You may wish to discuss with me before-hand on potential topics. Previous years’ presentation topics include SZ effect, Limb darkening, Bok Globules, Faraday rotation, Cherenkov radiation, Gunn-Peterson effect, Large velocity gradient method, determining mass of molecular clouds, Damped Ly-alpha systems, spinning dust and CMB foreground.... The above ‘Links to useful papers’ may be helpful.
