Dear Kirill,
Your text isn't ideal, but we can continue in the second semester to work on it.
I can propose you 45/50 for work in semester, it's first 50.
As for the second 50 for exam: you have extra 20/50 to improve the text before exam and there are 30/50 for answers to the questions of the ticket .
Please adress my comments in the attached file for such improvement.
y-photons cannot play the role of dark matter, because they are massless particles, while dark matter should correspond to dust with nonrelativistic equation of state p=0.
Regards
M.Yu.Khlopov
