The brainfarts never end. In the list of exam problems, problem set 4 appeared twice. Thanks to Jakob for pointing this out, and my apologies again to everyone. 

Here is the corrected list.

First of all, there was an error in the numbering of the problems in problem set 9. It is problem 3 (and only problem 3) in the problem set in the link below which may appear on the final exam.

Problem set 9

There will be no more organized teaching before the exam. If you have questions about the problems (or anything else), I can be reached by e-mail, or you can find me in my office. You are welcome to see me any time, but I will reserve Monday 10:15-12, Tuesday 12:15-14, and Thursday 14:15-16 for you, so then I am especially available.

To the exam you may bring 2 A4 pages of notes (1 double-sided or 2 single-sided sheets) and an approved (by God and the authorities) calculator.

We will meet at the usual time today, 10:15, to talk about what you want to do with the time we have left before the exam.

Since most of you have to hand in a very complicated project in AST3310 tomorrow, I have decided to extend the deadline on project 2. You should hand it in by 23:59 on Sunday, May 27th.

I made an algebraic mistake when setting up problem 1 in problem set 11, leading me to draw the wrong conclusion about the growth of dark matter density perturbations, so I have corrected question e).

Corrected version of problem set 11

Unfortunately there were some quite serious typos in problem 5 in the first version of project 2. Here is the corrected version. I apologize sincerely for any problems this may have caused you.

We will look at these problems.

Here is the amazingly cool project 2! After you have finished shouting "Hurrah!" with an annoyingly loud voice, please note that the deadline for this project is Friday May 25th at 23:59. Delivery by devilry, as usual.

As we agreed on Thursday, there will be no lecture on Monday 30th. The next lecture is on Thursday May 3rd, and I will then start on chapter 6: Structure formation.

Finally, you get the solutions to last week's problems.

Update: The solution of "the real problem 2" is missing in the link above. Here it is.

There will be a lecture tomorrow, Tuesday April 24th. Also, the exercise session will be replaced by a lecture on Thursday, April 26th.

The lecture is cancelled because of illness.

Publisert 10. apr. 2018 09:38

This week the exercise session is replaced by a lecture. I will continue covering chapter 5 in the lecture notes.

I have noticed that quite a few of you will have a struggle on your hands to hand in the project in time, partly because the numerical solution for the inverse power-law potential is a bit tricky. Since I will not start looking at the projects before Monday, it is perfectly OK if you submit it before 8am on Monday. 

Publisert 4. apr. 2018 09:07

To hand in project 1, go to devilry.ifi.uio.no and log in with your UiO username and password. Remember that you should hand in both your solutions to the problems and a file containing your code in a form that can be compiled and run (so not just a printout of your code). 

The deadline for handing in the project is Friday 6th of April at 23:59. Please do not write your name anywhere in the project. The system has been set up so that Mattia and I only can see candidate numbers, not names, because grading should be anonymous. 

As a final piece of advice: Make use of the opportunity to come and ask Mattia and I about anything related to the project tomorrow, Thursdag, between 14:15 and 16:00 in room 304.

Here are the solutions to this week's problems.

I wish you all a great Easter break, and I look forward to seeing you again on Thursday April 5th.

The week March 19-23 is, as you know all too well, the week for midterm exams. To give those of you who are afflicted by this curse some relief, there will be no activities in AST3220 during that week. We will meet after Easter for the problem session on Thursday April 5th which will be devoted to project 1.
