These are my notes for a course in stellar physics that I am teaching, the full set of lecture notes is here https://www.as.arizona.edu/~mrenzo/courses/lectures.html and includes some more on neutrino cooling in evolved stars, core collapse physics, and a guest lecture (also with notes that I am NOT the author of) on high energy neutrinos, but if you want to learn specifically about neutrino astrophysics this is certainly not the most comprehensive resource.
Re neutrinos, I would also mention KM3NET which looks for Cherenkov flashes in the Mediterranean sea used as a detector, which recently detected some extremely high energy neutrinos, e.g.:
Author here: this are my notes on what I mean to say in class, the website contain my whole course.
This particular lecture is still “in prep“, in fact the section "the problem" is just a bullet point and a figure. All other lectures are a bit more polished.
